Reference Codebot.Render.Graphics.pas

The Codebot.Render.Graphics unit provides 2D vector graphics through the ICanvas interface, which is drawn using Codebot.Render.NanoVG. A canvas draws paths, images, sprites, and text using pens, brushes, and fonts.

The unit defines the following interfaces:

• IMatrix is a 2D transform.
• IBitmap is an image, and IRenderBitmap is an image that can be drawn to.
• IFont describes how text is drawn.
• IPen strokes paths, and the solid, linear, radial, box gradient, and bitmap brushes fill them.
• ISprite draws a single cell of a sprite sheet.
• ITextWriter writes formatted text over several lines.

A canvas must be created and used while an OpenGL context is current.
