Initial release of BitmapPlusPlus Ruby bindings
Complete Ruby bindings for the BitmapPlusPlus C++ library using Rice
Support for creating and manipulating 24-bit BMP images
Drawing primitives:
- draw_line - Draw lines using Bresenham's algorithm
- draw_rect / fill_rect - Draw rectangle outlines and filled rectangles
- draw_triangle / fill_triangle - Draw triangle outlines and filled triangles
- draw_circle / fill_circle - Draw circle outlines and filled circles using midpoint algorithm
Pixel manipulation:
- get(x, y) / set(x, y, color) - Get/set pixels by coordinates
- [] / []= - Array-style access by linear index
- Bmp::Pixel class with RGB component access
Image transformations (immutable, return new bitmaps):
- flip_v - Vertical flip
- flip_h - Horizontal flip
- rotate_90_left - 90-degree counter-clockwise rotation
- rotate_90_right - 90-degree clockwise rotation
File I/O:
- save(filename) - Save to BMP file
- load(filename) - Load from BMP file
- Constructor accepts filename to load on creation
Iterator support:
- each - Iterate over all pixels
- each_reverse - Reverse iteration
32 predefined color constants (Aqua, Beige, Black, Blue, etc.)
Bmp::BitmapHeader struct for accessing BMP file header information
Bmp::Exception for error handling
RBS type signatures for static type checking
Minitest test suite
Example scripts (fractals, random colors, drawing primitives)
