- Correct usage of disposal methods (and possibility to generate records
with "restore previous frame" disposal method)
- Create color maps for each frame when necessary
- Remove options to dither RGB images (to simplify encoder)
When we converted an Indexed image to RGB, the original sprite
transparent color was being kept but the mask color of all its images
was reset to 0. With this change we kept the same mask color on all images
to avoid an assert() in the render code.
Anyway the whole RGB <-> Indexed conversion should be reviewed in these
cases. I think there are some situation where a transparent color = 0 is
expected in RGB sprites (as we shouldn't be able to change the transparent
color of an RGB sprite).
This include several changes:
- Color::getIndex() can return palette values with alpha != 255
- Fix Transparent and Blurs ink for indexed images to make better use
of palette entries with alpha values
- Fix bilinear resize algorithm for indexed images with alpha
- New RgbMap with four parameters: R, G, B, A
- Add one extra color scale function used in the alpha channel of the
new RgbMap
- Fix color curve, convolution matrix, invert color, and median filters
to take care of this new alpha channel on indexed images
- Fix ordered dithering and quantization
Related to #286
- Added doc::BlendMode enum and doc::BlendFunc type
- Renamed LayerImage::getBlendMode() -> blendMode()
- BLEND_MODE_COPY is BlendMode::SRC now
- BLEND_MODE_NORMAL is BlendMode::NORMAL now
- Added app::cmd::SetLayerBlendMode
This problem was introduced in d732f5b05f33ed1fce4c8b900a54f617bfb4c5ae
Now image_iterator.h and image_bits.h use forward declarations. And if
someone want to use the Image implementation, ImageBits, LockImageBits,
ImageIterators, or some function inside primitive_fast.h, they just have
to include image_impl.h file.
Changes:
* Create render library (move util/render.cpp to render/render.cpp)
* Move app::Zoom class to render::Zoom
* Remove doc::Image::merge() member function
* Add gfx::Clip helper class (to clip dst/src rectangles before a blit)
* Move doc::composite_image() to render::composite_image()
* Remove doc::Sprite::render()
* Replace Sprite::getPixel() with render::get_sprite_pixel()
* Remove doc::layer_render() function
* Convert DitheringMethod to a enum class
* Add AppRender to configure a render::Render with the app configuration
* Move checked background preferences as document-specific configuration
* Add doc::Sprite::layer() and palette() member functions
* Add doc::Layer::cel() member function
* Add doc::Palette::entry() member function()
* Add doc::frame_t type
* Move create_palette_from_rgb/convert_pixel_format to render library
* ExportSpriteSheet doesn't need a temporary image now that we can specify
the source rectangle in the render routine
