Is there a minimal package for Windows Bitmap (*.bmp) files?

Is there a package with minimal dependencies that supports loading and saving Windows Bitmap (*.bmp) files?
At present, ImageMagick.jl and OpenCV.jl are registered in the registry of FileIO.jl.

github.com

JuliaIO/FileIO.jl/blob/8a3398133445e47f036c304ba2e16b4932257513/src/registry.jl#L192-L198


      
          add_format(
              format"BMP",
              UInt8[0x42,0x4d],
              ".bmp",
              [idImageMagick],
              [idOpenCV]
          )

They are prone to compatibility troubles due to binary package dependencies.

You should check out this package:

That package is not registered, so it is no good at all.

It also does not support RLE compression.

Fortunately, the only BMP image provided by TestImages.jl is not in RLE, so TestImages.jl might be able to drop its dependency on ImageMagick.

Hopefully it gets registered soon.
