In Corel Painter, you work mainly with bitmaps, also known as raster images. Shapes, however, are vector objects. You can work with them in Corel Painter in much the same way you work with vector objects in drawing programs like CorelDRAW and Adobe Illustrator. For more information, see Exporting Adobe Illustrator shapes. Vector graphics are made up of lines, curves, objects, and fills that are all calculated mathematically.
When you create a shape in Corel Painter, the shape appears on a special shape layer. To maintain all of the editing properties of a shape, the shape must remain on the shape layer. However, you convert the shape to a pixel-based default image layer, so you can apply effects, transformations, or use painting tools. For more information, see Converting shapes to image layers.
You can also convert shapes to selections and vice versa. The tools for adjusting shapes allow precise control over the outline path, so you may want to use shapes to create some of your selection paths. For more information, see Converting selections to shapes.
