Can anyone think of an efficient way to convert a string full of RGBA image data to BGRA, using only what's available in the standard library? I'm trying to add a function to PyGUI for creating an Image object from arbitrary data. The problem I'm having is that GDI+ on Windows expects BGRA, whereas most other platforms deal with RGBA. I don't want to require the user to supply the data in different formats on different platforms, so PyGUI needs to be able to convert where necessary. I know the conversion can be done easily using something like PIL or numpy, but I'm after a solution that doesn't depend on any third-party libraries. -- Greg |
