- Implement pixel manipulation: set, get, and clear individual pixels with color data.
- Implement basic shapes:
- Draw lines.
- Draw rectangles.
- Draw circles.
- Draw ellipses.
- Draw polygons.
- Support filled versions of shapes.
- Support outlined versions of shapes.
- Implement bitmap rendering:
- Render 2D images (tga) to the framebuffer.
- Support transparency via alpha channels.
- Support transparency via a key color.
- Implement text rendering using psf fonts.
- Support RGB color format.
- Support grayscale color format.
- Support indexed color format.
- Add utility to convert between color formats.
- Support alpha blending for semi-transparent rendering.
- Add windowing support:
- Define sub-framebuffers (windows) within the main framebuffer.
- Maintain independent clipping for each window.
- Implement clipping to respect rendering boundaries.
- Implement 2D transformations:
- Scaling.
- Rotation.
- Translation.
- Transform relative to origin or center.
- Add optional anti-aliasing for smoother shapes and lines.
- Implement image manipulation:
- Scale tga.
- Crop tga.
- Rotate tga.
- Implement gradients and patterns:
- Fill shapes with gradients.
- Fill shapes with pattern-based textures.
- Optimize batch rendering to minimize CPU cycles.
- Add hooks for hardware acceleration (optional).
- Provide initialization routines for creating and managing a framebuffer.
- Ensure platform independence:
- Abstract hardware details for Linux framebuffer.
- Abstract hardware details for SDL2.
- Add support for reading framebuffer content to standard image formats (e.g., BMP, PNG).
- Add support for writing framebuffer content to standard image formats (e.g., BMP, PNG).
- Develop diagnostics tools to inspect pixel data.
- Add debugging overlays (e.g., FPS, gridlines).
- Implement graceful error handling for out-of-bounds operations with informative messages.
