## Filling shapes

Any shape may be filled with a colored pattern (including the uniform pattern) by first selecting the shape and then choosing the appropriate pattern in the "Fill" tabpane of the Attributes Editor.

The following patterns are available when exporting to PSTricks:

- no filling
- Uniform filling with a color that can be chosen, either amongst the available colors in the `predefined` pane (these are actually predefined PSTricks colors) or the `Swatches` pane, or by altering color components separately in the RGB (red-green-blue) or HSB (hue-saturation-brightness) panes.
- Filling with vertical lines; default angle is 45 degrees CCW. Color is to be selected from the color-chooser of the `Hatches` tabpane.
- Filling with vertical lines and a colored background; the background color is to be selected from the `Fill` tabpane.
- Filling with horizontal lines; default angle is 45 degrees CCW. Color is to be selected from the color-chooser of the `Hatches` tabpane.
- Filling with horizontal lines and a colored background; the background color is to be selected from the `Fill` tabpane.
- Filling with crosshatches ; default angle is 45 degrees CCW. Color is to be selected from the color-chooser of the `Hatches` tabpane.
- Filling with crosshatches and a colored background; the background color is to be selected from the `Fill` tabpane.

Other tips that may prove useful:

1. You can also fill an OPEN polygon like
   which results in
2. A triangle made up of three independant lines is not a closed polygon, so that it cannot be filled as is; the workaround consists in selecting the three lines, right-clicking to open the context popup menu, and selecting `Join selected curves`. Now the three lines form a single path that can be filled like any other path.
3. A ring section can be filled the same way: simply draw the corresponding arcs, select them, and then select `Join selected curves` (arcs are then converted to Bezier curves on-the-fly).
4. A ring can be filled by drawing to circles, making sure that the innermost circle sits on top (by invoking `forward` in the popup-menu), and then filling the outermost circle in whatever color you may wish, and finally the innermost one in white.
