About the BMP format
BMP — Bitmap Image File
BMP is an uncompressed raster image format native to Windows. It stores color data for each pixel individually without any compression, resulting in very large file sizes but perfect image fidelity.
Common uses
- Windows system graphics
- Intermediate file format for editing
- Print-ready artwork
- Legacy applications
About the RGBA format
RGBA — Raw RGB with Alpha
RGBA is a raw pixel format that stores red, green, blue, and alpha (transparency) channel values sequentially without any file header or compression. It is used as an interchange format in image processing pipelines where simplicity and directness are more important than portability.
Common uses
- Raw image data interchange in processing pipelines
- OpenGL texture loading from raw pixel buffers
- Intermediate format in image conversion tools
- Scripting and programmatic image generation
