img2bmp32 converts images to 32-bit BMP with pre-multiplied transparency (for Windows binaries). Converts many image formats (GIF, JPEG, PNG, TIFF, WMF, EMF, BMP, and ICO) to 32-bit BMP with am alpha channel. The alpha channel is pre-multiplied which is required for Windows BITMAP resources. Programs like GIMP don't do the pre-multiply step and cause the images to display very oddly when used. All command line arguments are treated as images to convert to BMP. The files are renamed to have the "bmp" extension.

Requirements:
* .NET Framework
* Visual C++ 2008 runtimes
