What happens to your file
BLP is the Blizzard texture format. It is palette-based but does keep an alpha channel, and Pillow will not quantize for it automatically — so the image is explicitly reduced to 256 colours using a fast-octree palette with Floyd–Steinberg dithering.
Settings this conversion runs with
| Engine | Pillow (Python Imaging Library) |
|---|---|
| Colour mode | 256-colour palette with alpha (fast octree, Floyd–Steinberg) |
What changes
- Transparency survives, but colour fidelity does not: 256 palette entries is a hard limit for textures with gradients.
