Modernizing Legacy Windows Bitmap Assets

Windows Bitmap (BMP) files store uncompressed raster data but lack multi-resolution encapsulation. Imgora takes single-resolution 24-bit or 32-bit BMP files, generates the missing scaling tiers (from 16×16 up to 256×256), and constructs a valid multi-image icon container.

Uncompressed Color Reproduction

Because BMP source files are uncompressed, they provide clean, noise-free pixel inputs that downsample with maximum fidelity across smaller icon dimensions.
