Scanning Images with Twain



Twain allows you to import images from a variety of sources that support the twain specification. These may be scanners or desktop web cameras or a number of other imaging devices.

If you only have one imaging device on you machine, you can press the "Scan" button. This activates the software that was installed with your device. This software will vary from one device to another.

If you have more than one, you can select the imaging device you wish to use with the "Select Scanner" button.

If you do not have a twain compatible scanner or imaging device, or your device is not installed or functioning correctly, you will not see it here.

Once finished, your current document will be replaced with the newly scanned image. You may or may not have to close the scanning software, but PD will not be locked from use. It will however ask you if you want to replace your current image.

Supported Color Formats

Most scanning software supports more than one color format for scanning images. Black and White, grayscale, 8 bit, and true color formats are common. Others may include 16 bit, and 48 bit. Not every format is supported by PD Pro, and all supported formats will be converted to the native 32 bits format. If you are not able to scan in a particular format, then scan in true color and perform the desired operation inside the program, such as converting to grayscale or black and white.




Scanning Frames for Animation




For animators, it is possible to scan multiple frames in a row. This process is necessarily slow and painful, but the results can be quite amazing.

Running the Scan animation item from the animation menu will open this panel. It will also invisibly initialize an animation for you.

You should create an image of the size you want your frames to be BEFORE you start to work this this feature. Scanned images will be scaled to the current image's size.

This feature will not lock out the user from the going back to the program and playing with other tools, but it is recommended that you do not. When scanning stacks and stacks of paper for ours on end, it is best to concentrate on what you are doing, and not risk messing anything up.

When you scan a frame, it will be added to the next available frame in PD. If you were to slide the animation scrub bar, be sure to leave it at the end of the animation when your done or you might put your frames out of order. It is however possible to use this to go back and re-scan a frame, should you need to.

The Frame control shows you the current frame as you scan.

The Rotation control lets you change the orientation of your paper. You will most likely want to do this to preserve the 3:4 aspect often used in animation.
