img2bmp32: Fast Command-Line Converter from IMG to 32-Bit BMP

What img2bmp32 is

• Purpose: A Windows command-line utility that converts many image formats (GIF, JPEG, PNG, TIFF, WMF, EMF, BMP, ICO) into 32-bit BMP files with a pre-multiplied alpha channel suitable for Windows bitmap resources.
• Why it exists: Windows BITMAP resources expect pre-multiplied alpha; common editors (e.g., GIMP) may not pre-multiply alpha, causing incorrect display when used as resources. img2bmp32 fixes that by producing pre-multiplied 32-bit BMPs.
• Author / Source: Created by “Coder For Life”; listed on the developer’s site and on download portals.
• Platform & requirements: Windows; built with Visual C++ CLR. Older builds require .NET 2.0 and Visual C++ 2008 runtimes (x86/x64 executables available).
• Usage: Command-line tool — pass image paths as arguments and it writes .bmp files (optionally overwriting). Typically used in workflows that embed BMPs into Windows binaries or resource editors.
• Notable details: Produces pre-multiplied alpha (important for correct rendering in resources); small standalone utility with source code available on the author’s site.
