CavePaint is a vector graphics program to create drawings. A library of objects allow the creation of rectangles, circles, arcs, ellipses, Bezier curves, lines, annotation text, geometric text, etc. Objects can further be modified changing colors, line thickness, backgrounds, shades, etc. All basic standard editing features are supported (background color, gradients, arrows, dashes, line thickness, textures, fonts, etc.).
CavePaint allows importing GIF, JPG and PNG pictures. Once imported, pictures can be processed by a suite of filters to change contrast, colors, transparency, lightning, distort, etc.
Any object you create can be transformed into a picture. Any picture or object can be exported to jpg, gif, png, and postscript formats. Large images can be printed into multiple pages.
CavePaint support Bezier curves editing. Any object (text, rectangles, etc.) can be transformed into a Bezier curve.
The program supports two types of text: annotation and geometric. Annotation text does not distort due to rotations or changes of the page where it is located. Geometric text can distort.
You can create diagrams connected by rubber band connectors. Move a block and the connecting line moves with it.
