# BMP-FI Windows or OS/2 Bitmap

Extensions: `.bmp`

A BMP format based on the Freeimage library.

This format supports grayscale, RGB and RGBA images.

The freeimage plugin requires a freeimage binary. If this binary not available on the system, it can be downloaded manually from <https://github.com/imageio/imageio-binaries> by either

- the command line script `imageio_download_bin freeimage`
- the Python method `imageio.plugins.freeimage.download()`

## Parameters for saving

compression : bool
  Whether to compress the bitmap using RLE when saving. Default False. It seems this does not always work, but who cares, you should use PNG anyway.
