Here are questions and answers as seen on the official Dogwaffle forum at the NEW Yahoogroups - Please  join to participate in discussions and learn more about Dogwaffle.We will answer your questions, for the benefit of others too. We are now also on Steam



Hot topics:

- Unexpected Error; Quitting?   --- How can I run two or more installed versions of Dogwaffle?


If you already had some version of Dogwaffle installed (e.g. PD Howler, PD Artist, PD Particles, old PD Pro, free versions, Trial demos,...), and then installed a new version, and later tried to run the old prior version again, you may notice that the prior version won't start anymore.

This can be easily fixed.

If you want to keep using multiple versions, you may need to run it as Administrator once again. Here's how to automate that so you don't have to right-click everytime.

- Problem with the Temp folder? Can't Launch Dogwaffle? Run-time error '424'?

Did you see a problem error message about the Temp folder not found? Or Runtime error 424? Is Dogwaffle failing to launch?

- Visual Studio 2010 SP1 runtimes

Some versions of Project Dogwaffle use Timosoft controls that require Visual Studio 2010 SP1 runtimes. 
We do not currently install them.  Most systems have them by default.  If it becomes possible, we will include them, but they do not make v2010 available for download anymore. 
The solution is to download the runtimes manually from here:

 - with PD Pro 8.2:  How to disable the GPU
Concurrency: parallel_for_each is not supported on the selected accelerator "CPU accelerator" 


- for PD Pro 7:  You need support of SSE2

Older computers supported MMX for multimedia acceleration. Newer computers  have added support of  SSE and eventually of SSE2 for an even richer multimedia experience. PD Pro 7 (Artist edition as well as Howler edition) requires a computer chip (Intel, AMD,...) that  supports SSE2. This is important to remember especially if you plan on using PD Pro 7 in a Virtual machine, such as Parallels or VMware Fusion, Dropbox or with CrossOver, Wine or PlayOnLinux:  It's not enough to have hardware that supports SSE2..... You also want to make sure that your VM supports it too.

A previous instance of Dogwaffle or Howler has crashed or failed to completely shut down.  Use Task Manager to shutdown any instance of Dogwaffle.exe processes. You can launch the Task Manager in a few ways, such as using CTRL+ALT+DEL keys or RIGHT-CLICKING the task bar (usually at the bottom of the screen) and selecting Task Manager.

  - PD Pro 5.1b - how to install or upgrade step-by-step

A step-by-step guide for updating from 5.0 or 5.1(TGE) to 5.1b can be found here
 
 - VB 5 - Visual Basic 5 Runtimes

If for some reason the installation of Dogwaffle fails to install and register the VB5 runtime files (dll's), you might want to install these separately. Microsoft offers the VB5 runtime installer here:  http://support.microsoft.com/kb/180071
 
 - PD Pro 5: "unknown error - quitting" occasionally seen after 3.7, 4.1 or 5 updates

You may need to
(1) disable UAC; 
(2) right-click to 'Run as Administrator' (just once); 
(3) disable  the antivirus (just temporarily);
(4) manually create a 'Temp' subfolder in the PD Pro folder; or
(5) all-of-the-above

If you are unable to launch PD Pro 4.1 (or other versions) after applying the update patch on top of 4.0 (which worked fine before), then you probably just need to run it once as Administrator, so that it can create a Temp subfolder inside the folder where you installed PD Pro. If you are using Windows Vista or Windows 7, with UAC enabled, it is likely to prevent creation of such a subfolder in the Program Files folders. You can either create the Temp sub-folder manually yourself, or run Dogwaffle as Administrator, so that it can override UAC and create the Temp folder when it finds that it doesn't exist yet. This is only needed once, just to create the Temp folder for Dogwaffle. Within the Settings options (File->Settings...) you may be able to change the location of the Temp folder thereafter, but at first, it will try to create one within the installation folder of PD Pro, and UAC is designed to prevent such a thing. We have also seen some rare antivirus programs with 'tottal protection' behave in ways similar to UAC, and thus even when disabling UAC you still weren't able to create the Temp folder where needed. In such cases you may need to temporarily disable the antivirus program too. We recommend that you disconnect the system from the internet during that time.

If this doesn't fix it, you can also manually create the Temp subfolder in the area where you installed Dogwaffle.


Compatibility modes
                under 64-bit Windows- PD Pro 5: Compatibility Modes under 64-bit OSes (Win7/64)

If you're running under 64 bit Windows you may have to set the compatibility settings up like in this screenshot. Select the Compatibility Mode (example shown is for Windows XP with SP3). Right-click the dogwaffle.exe shortcut on your desktop or from the Start menu, and select Properties, then select the Compatibility tab.

- Run in Windows XP SP3 compatible mode
- Disable Desktop Composition to improve speed of visual feedback/interaction

Your experience may vary, some of it is affected by graphics drivers, perhaps. Try this.


- Icons and buttons are flashing and/or are sluggish.

Solution: Possibly a driver or bandwidth issue.  Changing from a 32 to 16 bit screen may resolve the issue.  This may vary depending on your graphics card's driver. Another solution may be: Go into properties for the program (right-click->Properties), then go to the Compatibility tab and click 'disable desktop composition'


 - .NET (dot Net) Framework 4 required (PD Pro 5)


If you see an error message similar to this when using certain new plugins for Dogwaffle:
    AppName: dogwaffle.exe AppVer: 4.0.0.0 ModName: unknown
then you may need to bring your system's .NET framework up to a more recent version, at least version 4.

See more details here: dotnetframework

Learn more about PD Pro 5 here too.


  - "Overflow Error code 6" under 64-bit Windows  
Under Windows XP there was no problem, but since you switched to WIndows 7, you can't seem to create an animation. Everytime you select the menu:  Animation -> Create...
the program exits with an error message. See here for a work-around... CreateAnim2 plugin


  - Installation Problems? Where is the Temp folder?
The Installer for Project Dogwaffle goes through two phases. In the first phase, it extracts a bunch of files into a Temp folder. One of these files is named SETUP.EXE. In the second phase, it runs that Setup file, which will guide you through the rest of the installation. Depending on the state of your system, you may have sometimes observed a problem during the second phase. It may be that a different Setup.exe file is found somewhere else, coming from a different installation, a different, unrelated program, and that one is executed instead of ours. In cases like these, one workaround is to find the Temp folder here all these files were extracted, and run the SETUP.EXE file manually. So therefore, this begs the question: where is the Temp folder?

In Windows XP, it's usually  C:\Documents and Settings\'username'\Local Settings\Temp
For example, if your username is 'Peter', you will likely have a folder like this:

      C:\Documents and Settings\Peter\Local Settings\Temp

Under Windows Vista it is likely something like this:   C:\users\'username'\AppData\Local\Temp
For example, if your username is 'Peter', you will likely have a folder like this:

       C:\users\Peter\AppData\Local\Temp

Go to that folder, and run the setup file from there.

Note that if you can't find the 'Local Settings' or Temp folder under XP, you may a configuration of Folder Options that hides the hidden files and folders. To change that:
  1. go to the Control Panel
  2. open Folder Options
  3. click the 'View' tab
  4. check 'Show hiden files and folders'
  5. while you're at it, we als recommend this: uncheck 'hide extension of known file types'
  6. click OK




- Too much Lag on your TabletPC ?

If you're trying to use Project Dogwaffle on a TabletPC (you know, one of those oh-so cool laptops where you can draw directly on the screen with a stylus) and you're experiencing significant pointer cursor lag while drawing with Project Dogwaffle (and likely other applications too) even after downloading the latest driver from Wacom, then you may be interested in taming tabtip.exe for the benefit of the Wacom driver's responsiveness. Check details here:

http://www.cartoonmonkey.com/TabTip_TamerV3.htm

TabTip-Tamer is an ESSENTIAL application that eliminates cursor lag when using many graphics apps that utilize Wacom's pressure sensitive Penabled pen driver on the Tablet Pc.






- Can't see Videos? need new Codecs?

If you can't see a video such as from a tutorial in WM3 codec format, consider
Another great resource for all things related to video codecs is www.codecs.com (same as www.free-codecs.com) - recommended tools and utilities: VirtualDub, Gspot, Media Player Classic, ...

==> Look also for ffmpeg at www.ffmpeg.org - it has a built-in mpeg4 encode/decoder and copnverts to many other formats. Great for batch/script-based converting.

==> Look also for the XPcodecPack (at http://www.xpcodecpack.com)


If the video requires a codec such as Xvid or similar, check here for options.



- Runtime Errors? 

Did you get Runtime Error 75 during installation? Perhaps the installation suceeded for the 4.0 version of D Pro, but failed for the 4.1 update, with error 75? “Runtime Error 75; Path/File access error’’

As the error indicates, something failed to install because it couldn't access a path to a folder or a file. The question then is: which file, or why did it fail to access it? The answer may lie in your antivirus program, preventing access to files belonging to the VB runtime or anything, existing or not, in the WINDOWS or system32 folders. One solution might be to temporarily disable your antivirus program and try installing again. Be sure to re-enable the a/v program thereafter.

 > error 401 or others, perhaps your registry entries got corrupted. You may want to reset (clear) the entries used by Dogwaffle, either for just the panels, or the whole program (but only for Dogwaffle).  Learn more about the free utility:  DogClearReg

However, read also further below about Runtime error 5

Another possibility seen in a few rare cases was that the system ran out of Virtual memory, i.e. reached the limit int the PC's configuration settings. Perhaps a video game had been running and used lots of memory still allocated by Windows or a game support utility, or tons of websurfing with pages using Java or other memory intensive programs were just too much for the PC? A good thing to try is reboot if in doubt. You may also need more RAM, or check and increase the virtual memory. Contact us if you have questions about this.

- Viewing Controls for working with 4-5 megapixels camera's Digital pictures and beyond?

PD is intrinsically a bitmap program.  I won't argue the benifits of  Bitmaps vr's vector painting.  Just pointing out what it is.  Much like digital photographs, to get better quality, you'll have to work  with larger images. There are a few keyboard shortcuts you should be familiar with for
working on larger images.

CTRL+SHIFT.... Pan around in the image with the Left Mouse Button
                or
zoom with the Right Mouse Button.
CTRL+ALT...... Same as CTRL+SHIFT
F3............ Zoom to 100%
F4............ Zoom to fit window
Home.......... Center the image
n............. Center the area under the cursor. Use this
                   to center on your point of interest.

CTRL + ....... Magnify by 25%
CTRL - ....... Minify by 25%

There are other very useful shortcuts, be sure to read the shortcuts page in the Help area.






- Tablet pressure data problems:

Question: I have a tablet, and it works with other programs, but Dogwaffle doesn't recognize the pressure. I can't make it change the size or the opacity with pressure even though I enabled them in the checkboxes in the Brush Settings panel. What's wrong with my tablet?

Answer:  Nothing's wrong with your tablet, and there's probably an easy fix with the VBtablet library file. For details about VBtablet, read the Dogwaffle VB Tablet Support Page





Question:  I have a Tablet PC and Dogwaffle runs well but it doesn't seem to recognize the pressure from the stylus. Is there a fix?

Answer:  Try the newest enhanced drivers from Wacom, it has worked for others to fix this issue:

Question:
     Is there a way to Half-tone or Dither before printing?


Answer:
Yes there are several tools for this. In the Filter menu you'll find color controls for dithering.

There's also a Threshold tool to force to black&white.
Here are a couple of tips for converting images to black and white.
If you want to use threshold to make a b/w image, add a little value noise first.  This will give you a nice dither pattern when you threshold your image, and you'll have better control over it than simply using the 1 bit random dither.

Use the 'expand dynamic range' option to take full advantage of your color range before dithering down to 2 colors. Adjust your contrast before converting to 2 colors.  you won't be able to do it after.  Proper contrast will make a huge difference in 2 color images.

addendum:
You are not limited to any specific halftone pattern.  With a little imagination, you can create any pattern and use it as a halftone screen.

For example(and just an example)
- load an image that you want to dither down to 2 colors. 
- Press j to jump to the swap buffer.
- render plasma noise with one iteration and go back to the main buffer.
- Now combine the two buffers with the binary mode (filters/combine menu)
This will use the plasma noise that you rendered as your halftone pattern.
Now try it with other patterns.






Question:
How can I apply a series of images in a spray pattern?

Answer:
There is an icon in the Tools palette for Custom Brush selection.
Right-click it and you'll have the tool for Chroma-keying, i.e.
turkey-basting on the desired background pixel of the image preview and
that will be flagged as transparent. Make adjustments with the sliders.

That's how the leaves in the free animated brush were make. Did you see
them in the freebies collection?

Once that's done and you have just the object you want opaque and the
rest around it is transparent, there are special FX features in the brush
panel.
Left-click the upper-left-most icon in the Tools palette, that's the
brush panel, showing the details of the brush. The third tab in that window
is for special FX. Check the enabled box and select the drop shadow mode. The
sliders there affect opacity and distance (offset) and more.

Once you have created an animated brush, then create any drop shadows as a post
effect. www.thebest3d.com/dogwaffle/freebies has some examples.





Problem:
I purchased DogwaffleDE today and have had a number of problems trying to
install the software.

When trying to run the installer brought up another "extract" dialog
and when I tried to accept the default directory, it wouldn't allow it.
I then requested to extract to the Dogwaffle parent directory and this worked.

Working through the installer, I accepted the default location for installation but was notified that I was overwriting shared files.

Attempting to authorize this caused the installer to fail. Trying a second
time, (after reboot), I denied the overwrite and the install completed
giving me a success dialog. Upon trying to launch the program from the
start menu, however, resulted in the demo version being run, instead,
(this is after I uninstalled it and rebooted). So, now I am hopelessly
lost, and gee, I was hoping to spend the whole weekend learning this
most excellent program. Can you make any suggestions?

Solution:
It is recommended not to install over an older copy of the program. First try
uninstalling both, rebooting windows then installing only the version you wish
to use.

However this has also worked for some people:
Uninstall the older version of Dogwaffle, reboot Windows, run the "Setup"
program instead of the "install Dogwaffle" program.





Question:
Is there a shortcut for creating buildings with rectangular stones in
perspective with Dogwaffle?

Answer:
The closest thing I can think of is the rubber sheet plugin that lets
you warp an image by four control points.





Question:
Is there a series of effects that can be applied to produce
photorealistic looking rock and stone, where shadow and highlight
are painted in real time? A kind of 3D painting effect?

Answer:
You can experiment with loading different paper textures and using the
drybrush features.
You can try building textures by starting with fractal noise or the
cellular plugin, adding displacement, combining with other textures, applying
emboss, etc.

There's also the isometric 3d plugin that can be usefull for generating
fairly realistic stone imagery when starting with a noise image. The
wireframe designer also has a basic rendering capability in one of the
latter versions.

computer.







"runtime error '5' - Invalid procedure call or argument"

Question:
I've been having problems with Project Dogwaffle for a few days
now. I'd open the program and when it would come to the Buffer Size
window, I'd select the dimensions I wanted and would click Ok..but then
a window pops up saying:

"Run-time error '5':Invalid Procedure call or argument"

Can anyone tell me what I am doing wrong or what's happening?

Answer:
This is possibly a result of the registry settings for window
positions becoming corrupted.

You can run RegEdit to remove the offending entry
the settings can be found in the registry here:

  • For most versions of Project Dogwaffle (incl. PD Pro):
HKEY_CURRENT_USER\Software\VB and VBA Program Settings\dogwaffle\WindowData

  • For PD Particles:
HKEY_CURRENT_USER\Software\VB and VBA Program Settings\Optipuss\WindowData


Removing the entire WindowData entry is an option.

NEW! There is now a free utility available to clear the registry entries for Dogwaffle and PD Pro > DogClearReg






Question:
Hello all,
I'm rather new to graphics programs and I'm trying to do something
that hopefully isn't too hard. Basically I want to overlay a grid on
top of a map. I have the map and grid in two separate jpg files, so
is there a way to combine them together so the grid is on top? I
tried looking at the tutorial for the alpha channel, but it left me
confused. Perhaps I am out of my league.

Any help is appreciated.
Thanks.

Answers:
Yes you can do that. Load one image into the Main buffer, then swap to
the other and load the other image, then merge them in multiply mode.
Assuming the grid is black lines on White background, the merge will keep the
colors as is except where the black lines are, which will turn the color
black.

There's probably a way also with the "Rub-through" brush.

-Philip

An easy way might be to load the map, then load the grid as a brush,
from the brush menu/load command.  Then you can key out part of the
grid with the brush keyer - (right click on the brush selector tool
on the tool panel to get the brush keyer)  then you can just place it
where you want and stamp it down.  If the grid is a different size
than the map, you can scale the brush from the brush menu.
Another option would be to swap screens "j" and stamp it down by
itself and use one of the many 'Combine with swap' options from the
filters menu.

Question:
fieldpackpm question:
What is it and what does it do?

Answer:
Field pack is an interlacer, deinterlacer and video retimer.

Each frame of a television signal is is composed two independent images called feilds.  While each frame is played at 30 frames per
second, what is really happening is two feilds are playing for each frame, at 60 fields per seconds.  These fields are interlaced, so
that 1 line is shown from the first field, then one from the second, and so on.  If you pause a television image, you may see this in
areas of fast motion.  The image appears to flicker because the two fields are being refreshed independantly.

When working with video, such as painting on or applying filters to
a vidoe sequence, it is often important to on each field
seperately.  Thus, with field pack, you can split a video frame
sequence up into independant images.  This way, you can work on them
seperately, then re-interlace them later.

Field pack goes a little farther than just splitting the images
though.  It uses several techniques to try to maintian as much of
the original detail as possible, instead of just interpolating extra
lines.

Also in field pack is the ability to retime a video sequence.  This
is more involved than just creating in between frames by blending
between neiboring frames.  A sort of morphing is applied to in-
betweens to create a more realistic looking motion.  Fieldpack first
deinterlaces the image, creating 2 seperate images, then
extrapolates another 2, leaving you with video that runs 4 times
slower.  It's possible of coarse to re-interlace the images to make
them look like normal video again, still leaving you with a 2x slow
motion effect.





Question:
I've been playing with the fx brush, and I'm having trouble
getting the anim brushes it makes to actually paint with their animation.
I know the frames are being built properly, because when I open
the brush manager, the brush's thumbnail animates. But when I paint
with the brush, it uses only the first frame.

Answer:
This is one of those anoying ones.  The problem is a limitation in
the plugin interface of 1.6.  When an animbrush is alocated for the
first time, a small structure is created with it containing, among
other things, the direction that the animbrush plays (a value that's
added to the frame count; 1, 2, -1, etc.)  When an animbrush is
initiated through the plugin interface, this structure is not filled
out, leaving it at 0.  The solution for now, is too be sure you've
had an animbrush initiated either by creating or loading one.  This
will be addressed in future versions.







Question:
In the optipustic's configuration menu, if I put the value of 1 into the drag
field, i can't get anything to show up on the screen no matter how I move the
mouse across it.  Any other value doesn't seem to cause problems. even 1.1
allows lines to show up but 1 gives me nothing.
any reason why?

Answer:
Drag is a bit odd.  It's a value between -1 and 1  0 is no drag and
1 is 100% drag and -1 is 100% negative drag.  It's really just a
value that lets you control the global speed of particles, including
the ability to make them do the opposite of what they're physically
supposed to do.






Question:
I can't seem to get the optipustics settings right. I'm tring to get the
particles to follow my mouse in long flowing curves, so that i can use it to
paint hair on figures, but either I get tight curves, or the particles follow
the mouse but in straight lines.

Any suggestions for settings?

Answer:
Turn the 'terminal velocity' way up.  It limmits the speed of
particles, otherwise they'd just keep accelerating - just like in
real life.  Turn 'use mouse velocity' off.  Play with the 'particles
follow mouse'

Question:
In the optipustics configuration menu, I assumed that max particles meant that
was the maximum ammount that could be created. but I was able to put 100 into
max particles then put 200 into particles per emmision. Which kinda looks like
even though I said no more than 100, I can get it to generate 200 every time it
emits particles.

So i'm curious what the max particles actualy refers to?

Answer:
Max particles referes to the very maximum number of particles that
can exist.  Particles per emmision referes to how many particles are
spurted out at any one time (that is, each time the program recieves
a mouse move event).  There will be no more than max particles.
When a particle reaches the end of its lifespan, it becomes
available for recycling.  For example, if you set max particles and
particles per emmision both to 100, 100 particles will be created on
the first mouse down, and no new particles will be created until
particles reach the end of their lifespan.  If you set max particles
to 100, then set particles per emmision to 10 and lifespan to 10,
you will have a constant stream of particles with no breaks in
emmision.
Of course, if you have splits set to a value above 0, then those are
taken from the available particles in circulation and the math gets
harder.






Question:
How can I erase while I'm drawing?

Answer:
The method for erasing generaly involves using the right mouse
button with the secondary paint color which is the color that a
buffer is cleared to when you hit clear.  It's a little trickier
with a pen.  If you need to toggle off the paper texture, you can
hit the middle icon on the upper part of the tool panel.  Saves the
step of opening the paper panel.  

   




Question:
How do I re-seize a custom brush?

Answer:
The best way is with the brush manager plugin that's part of Doggybag 1.
Another option is the resample item on the brush menu.





Question:
How do I effectively use the colour mixer. What is really the use of it?

Answer:
Some people like to mix their colors like they would with natural
media, and some are perfectly happy working with RGB values. The mixure
allows you this choice.






Question:
How do I paint on Alpha?

Answer:
First, lets define the alpha channel.  In a typical computer graphics
system, an image is contained in 32 bits per pixel, where each
channel is 8 bits.  There are 3 channels for color (red, green, and
blue) and one for transparency.  This 4th channel is the alpha
channel.  It is typically represented as a greyscale image with black
being completely transparent and white being completely opaque (or
the other way around)
In the case of painting programs, the alpha channel is used as a
mask, to define where paint can be applied.
Since this is a greyscale image, we don't simple superimpose it over
our painting because then we wouldn't be able to see what we're
working on.  Therefore, what is usually refered to as a 'selection',
or 'Marching ants' is actually a very crude representation of the
alpha channel.  A routine that separates the mid-point of the alpha,
(value 128) is applied to give a basic outline of the rouph shapes in
the alpa channel.  This can cause problems because the alpha may not
contain only completely opaque and completely transparent values.  In
fact, a function is supplied that will compensate for this case,
called 'Dynamic range' by expanding the values in the alpha channel
so the highest value is always 255 and the lowest is always 0

Lets go over a few alpha tools.
First, as a standard feature with all the alpha tools, there are the
following keyboard shortcuts that modify the behavior of the alpha
tools.
Holding the Control key is used to drag the alpha 'selection' around.
You can also use Shift and the Arrow keys to nudge the selection by
one pixel at a time.
Holding alt while using an alpha tool lets you add to or subtract
from the current selection depending on which mouse button you use.
Control + 'c' copies the current 'selection' as a custom brush.

The 'paint on Alpha' plugin lets you paint directly into the alpha
channel like a regular buffer.  Basically it copies the alpha
channel  to each channel of the main buffer, and when you're done
painting on it, you click the 'Paint normally' button and it gets
converted back to a single channel and copied back to your alpha
channel, and you get your original buffer back.

I might also mention at this point, we have two tutorals on working
with alpha tools.  http://www.thebest3d.com/dogwaffle/tuts/zipped/

When you use the paint on alpha plugin, your buffer is swapped out
with one that represents the alpha until you hit the 'paint normally'
button.  Then you get your old buffer back and the one you were
painting on gets converted to greyscale and copied to the alpha
channel.  For best results, you should paint with black or white.

Question:
Can I save colour settings?

Answer:
You can save a set of colors by right clicking on the mixer button at
the bottom of the tool panel.  This brings up a menu with options
like 'save wells'
There's also an option for building a new color well from colors in
your buffer, etc.














Question:
How do I change the color in the masked (Alpha) area?

Answer:
You have to go back to using the paint normal mode and select a brush
that paints normally, in case you did select one of the predefined brushes
which paint on alpha.

Try this:

- right-click on the built-in (predefined) brushes icon (second row
from top in Tools panel). There's a submenu for painting on alpha, try the
soft or blobby.

Now paint of the 'desired' area, i.e. the pixels which you'll want in
your selection. If you already had some selection in place, e.g. from the
lasso or magic wand selection/alpha tools, this m,anual painting will 'add'
to the selection or 'subtract' from the selection depending on whether you use
the left or right button to paint.

Once your selection is ready, select a normal brush again, and paint
over the selection. The mask will prevent undesired changes. You can
right-click on the Alpha (selection) tools (3rd row in tools panel) to see all
alpha tools such as grow or shrink ior invert alpha or smooth etc.






Question:
How do I get something to merge the two buffers?

Answer:
To merge the two buffers, do this:
Right click on the upper-right-most icon in control panel.

If one image is in the main buffer and the other is in the swap buffer.

You can have additional images in stored buffers and make them current
(main) later to mix that in as well.

Also try the flood fill tool (right-most paint can fill on 2nd row of
tools panel). If you start from a blank white it will fill at current color.

Right-click on the same flood fill icon to see the flood tolerance and
the fill gradient. In the gradient panel you have a row at top with several
modes. The will let you fill the gradient left to right, inverse,
top-down etc... and even fill an image which is in the brush into the window
(stretched) or even warp it to match the current selection. So there's
another way to blend or mix an image with another. If one is in the
Main buffer you can load the other into the brush, (e.g. through Brush>Load
or Brush Clipboard options) and then use the opacity slider to set the
level for the brush and fill or click to stomp it over the main buffer etc.





Question:
How can I put a flare over part of my image?

Answer:
But to put a flare over your image, I'd recommend instead to apply the flare
which is in the brush, directly to the timage. Use additive mode or multiply
mode depending on effect (instead of Default mode, which replaces). Use opacity
slider to affect the level of the stamp effect. Use 'a' (again) for repeeating again and
again until the desired level is there.

There's a shortcut for erasing to a color, but if the gradient/fill mode is to erase to the brush's image it uses that, use 'q' as shortcut.

So with all in place after you rendered the flare you can simply select
the mode in the gradient panel which warps the brush image into the
selection (or the whole window by default) or just simply applies it without
warping, then use the slider for opacity, then 'q' to flood fill, then 'a'  to
do it again and again as needed.





Question:
Is it possible to use the animbrush to create an animated arrow icon?

Answer:
Yes but typically, you would create a traditional animation in dogwaffle,
perhaps 5 - 10 frames, and wiggle or move or turn that arrow which you have in
the custom brush,  using the brush manager too, and advance from one frame to the
next until  each frame is done. Then you could collect them all into an animated
brush, so you could use that again in various settings and conditions.






Question:
Can you do Flash in Dogwaffle? Or at least something approaching it?

Answer:

No, but you can pack AVI files into Flash MX and there are some really
cheap tools like www.gif2swf.com which converts AVI and packs (embeds) it
into .swf files. There are other tools out there doing this. Check
www.tucows.com and look for Flash tools in Multimedia, I guess.
Or do a Google search for Avi to Flash conversion or similar






Question:
Dogwaffle only allows me to save it as a .dwa, and I can't view it unless it's
in Dogwaffle. What can I do to save it in a format my friend can see?

Answer:

Save it out as image sequnce or if you add the doggybag #2 (free
download from www.thebest3d.com/dogwaffle/whatsnew)  you can save to AVI also.

If you save as Targa image sequence you will find that many animation
programs can load that in and pack it into your target format like Avi
or Quicktime. For example Quicktime pro can do that.





Question:

How do I change the printing height of a dogwaffle sketch/painting?

Answer:
Personally I like to use Irfanview for image viewing and
printing. www.irfanview.com -  It's awesome also to set dpi info and
resample with Lanzcos and other  great filters for avoiding pixelation.
You don't even have to save to file, you can Control-C from the main
buffer to the brush, then menu: Brush>Clipboard and copy to the clipboard,
then Alt-Tab to a running session of Irfanview, Shift-P to print (after
perhaps 'L' or 'R' to rotate left or right ) and then you can find great ways
to print according to internal file info dpi or new size settings on the
fly.
