Module dagon.resource.sdlimage
Image decoder that uses SDL2_Image.
Description
The dagon.resource.sdlimage module defines functionality for loading
images via SDL2_Image, and converting SDL surfaces to GPU-ready texture buffers.
The loader supports a wide range of formats (BMP, GIF, JPEG, PNG, QOI, TGA,
TIFF, WEBP, AVIF, JXL, SVG, and more), and can handle pixel format conversion.
It also creates a TextureImage object for compatibility with dlib.image`.
