As a real painting, GMX-PhotoPainter pictures are composed of many overlapped brushstrokes, GMX-PhotoPainter provides three different painting tools which vary on how strokes are placed along the image:

AutoSketch

This tool automatically determine the brushstrokes directions. This means that the user does not need to move the mouse in a specific direction to guide the brushstrokes, the orientation of the brushstrokes will be obtained in an automatic way based on the characteristics of the image. In those areas where there are not significant variations of color, for example uniform backgrounds, completely black areas, etc., the automatic determination of directions will always create horizontal lines, for this reason it is convenient to make this areas with another tool as the free hand tool or the pattern tool.
How to use it:
Choose the it from the toolbar:
GMX-PhotoPainter - auto sketch tool
Move the mouse with the left button pressed throughout the area where you want the strokes appear. The resulting strokes will appear in the right panel.
The number of strokes drawn per mouse movement are determined by the “Density” parameter. The size of the area where this tool will be applied is determined by the “Size” parameter . Both parameters can be found in the “Size and Density” Tab in the Style Dialog Box.

Freehand painting

Note that the width of the strip will be determined by the size indicated in the “Size” parameter. The other strokes aspects will be determined by the Style Dialog Box.

Pattern

Description:

a pattern is composed of “variants”. More than one variant of the same pattern make the pattern less mechanical or repetitive. When the pattern tool is applied each variant is randomly choosed of all available variants. You can provide up to five variants, however two or three variants could be enough.

pattern pointer tool Pointer Tool: Use it to move the nodes.
pattern draw stroke tool Stroke Tool: Use it to draw the strokes.
