Canvas - Menus - Edit (continued)
Selection to Bristle...: Converts the currently selected area to a bristle. A dialog will appear allowing you to save the image to a suitable location. If the save operation completes successfully, a new bristle will be created with the same size and shape as the one previously selected. The new bristle's Image option will be enabled, and the file associated with newly-saved image will be loaded.
Crop Image: Crops the image to the current selection.
Paint Wrap: Allows the creation of seamless textures by taking any paint that lands beyond an image's border, and continuing it on the opposite side.
Draw Bristle Outline: Draws an outline of the bounding rectangle that encloses the currently enabled bristles. This makes it easy to determine exactly what area will be affected when painting.
