Artistic Filters

 

Apply current paper



Apply paper applies the currently selected paper texture to the image. You can select a paper texture from the paper panel while this filter is in use.


 

Wet paint



The wet paint filter extrudes pixels to give the appearance that un-dried paint is running down the image. Using a positive value makes the lighter colors run, and a negative value makes the dark colors run.


 

Brush strokes

The brush strokes filter applies stroke effects to an image along it’s contours.

Density controls how many stroke lines are applied to the image.

Max length is the length of the line

Angle is the overall angle the line should follow.

Max angle clamps the angle to a certain amount.

You can clear the image before drawing the brush strokes, or you can keep the original image intact, and the strokes will be applied over it.

The line type controls the appearance of the stroked lines. Anti-aliased lines look the best, but take longer to render.

Grad lines can give the appearance of hair or fur.

You can also apply the current brush as a brush stroke over the entire image, but beware this mode can take a long time, depending on the brush you have selected.


 

Tarnish

This filter creates the appearance of dirt and grime, or weathering over your image.




 

Weave

This filter renders a woven pattern over your image.




Graphic pen

The graphic pen filter can transform you picture into a pencil drawing, watercolor painting, or other style, using various styles.

The Scribble and Crayon styles seem to produce the most interesting results. They work by examining the contours in your image, and emitting particles that act like tiny paint brushes to follow them.

Pen size controls the size of the particle or paint brush

Stroke density controls how many particles are created. More take longer, and using the maximum value is not recommended. You should stop just short of it.

Stroke length controls the particle lifespan, or how long it continues to draw before it stops.

Turning on the Color check-box gives will paint the image in color, otherwise, it will look like a pencil drawing.





Oilify

The oilify filter applies an edge preserving filter than somewhat resembles an oil painting in appearance. There are two modes that give a somewhat different look.





Cross contour

In art school, you may have been taught a process know as cross-contour, in which the artist draws a line through a drawing, altering is appearance as he draws, to simulate what he is seeing. An accumulation of these lines then adds up to a picture that should resemble what the artist was viewing.

The filter does the same thing. It starts at the left side and scans across, increasing or decreasing the density of the line as it goes.




Wood cut

In wood cut printing, a piece of wood is carved with an image, and then ink is applied, and it is pressed against the paper to form a positive print. The image can be printed again and again using this technique.

The Wood cut filter can simulate the look of a wood cut design. It uses what is known as a threshold with guaranteed contrast.

You can apply up to 3 levels of threshold. Each level will receive its own grayscale level, ranging from black to light gray.
