# rays ChangeLog


## [v0.2.1] - 2024-07-05

- Add OpenGL_init() and OpenGL_fin()
- Add activate_offscreen_context()
- Do not redefine fin!() methods, they are no longer needed
- Update workflows for test
- Update to actions/checkout@v4


## [v0.2] - 2024-03-14

- Change the super class for exception class from RuntimeError to StandardError
- Fix compile errors on iOS


## [v0.1.49] - 2024-02-07

- Add point(), line_height(), and line_height!() to Painter
- Add translate!(), scale!(), rotate!(), transpose(), and transpose!() to Rays::Matrix class
- Add ortho(), perspective(), and look_at() to Rays::Matrix
- Add Color#to_hsv
- Add get_hsv()
- hsb as an alias for hsv

- Font::get_width() handles multiple lines if there is a newline character
- Painter::curve() and Painter::bezier() use nsegment state
- Polygon.curve() and Polygon.bezier() can take 'nsegment' parameter
- When updating a texture with a bitmap, the texture is reused, not created anew
- If the texture is bound to the frame buffer, replacing it with a new texture will cause the drawing target to shift
- Set the modified flag on the texture in the framebuffer at the beginning of painting
- Set modified flag for bitmap if needed
- Throw error on conflict between bitmap and texture

- Fix a bug that dust was drawn on the right edge when drawing text
- Fix that Painter#point ignores stroke_cap
- Fix Matrix::to_a order


## [v0.1.48] - 2024-01-08

- Add Bitmap#pixels=
- Add Font#dup, Font#size=, Font.families, and Font.load
- Add Polyline#with
- Add Painter#texture, Painter#texcoord_mode,  and Painter#texcoord_wrap

- Delete Polygon::Line because it was merged into Polyline

- Polygon and Polyline can take colors and texcoords for each vertex
- Polyline.new can take 'hole' parameter
- 'polygonA + polygonB' means Polygon.new(*polygonA.to_a, *polygonB.to_a)
- Polygon with only holes raises an ArgumentError
- Image delegates 'pixels' accessors to Bitmap
- Use GL_CLAMP_TO_EDGE for texturing
- Refine Point#inspect(), Color#inspect(), and Font#inspect()
- default_font() -> get_default_font()
- rays/include/noise.h -> rays/include/util.h

- Fix Polygon.bezier() returns broken object
- Fix get_pixels() does not work with float colors


## [v0.1.47] - 2023-12-09

- Add Polygon's singleton methods: points(), lines(), triangles(), triangle_strip(), triangle_fan(), quads(), quad_strip()
- Add create_polygon(DrawMode, ...)
- Add Painter#stroke_outset
- Add Bitmap#pixels
- Use earcut.hpp for polygon triangulation and delete poly2tri
- Painter#polygon() can take x, y, width, and height
- Polygon#bounds() caches bounds
- Polygon.line() -> Polygon.line_strip()
- Rays::Polygon.new() can take DrawMode
- Matrix(nullptr) avoids initialization
- Trigger github actions on all pull_request


## [v0.1.46] - 2023-11-09

- Use Gemfile to install gems for development instead of add_development_dependency in gemspec
- empty -> is_empty


## [v0.1.45] - 2023-10-29

- Fixed Image class to clear the update flag only when one of the bitmap and texture is being updated

## [v0.1.41] - 2023-06-08

- Point#normal() does not check 'length == 0'


## [v0.1.40] - 2023-06-07
