twobit-atlas is a Windows command line tool to generate image atlas sheets. It can generate atlases from a directory of images, specified true type font, or a combination of both.
Windows binary installer: https://github.com/foobit/twobit-atlas/downloads
To get the full list of options type the following at the command prompt:
twobit-atlas.exe --help
Texture Packing: Combine multiple images to a single compact image. Optionally use the --make-sprite option to create a sprite animation info file assocated with the atlas.
Auto Offset Registration: Images offsets can be automatically matched from the source dimensions. The alignment offset is stored with the atlas. Drawing from the atlas information will have glyphs line up correctly.
Glyph Layout: layout on the atlas can be placed in a grid or best fit.
twobit-atlas.exe --font Tahoma --font-size 24 --glyph-align BestFit -o tahoma24-fit.atlas
twobit-atlas.exe --font Tahoma --font-size 24 --glyph-align Grid -o tahoma24-fit.atlas
Interactive Console Mode: Generate atlases via a console menu twobit-atlas.exe -C
The tool can be expanded via C# assembly plugins during startup.
In addition the executable can be used as an assembly in your existing .Net managed projects. Just add a reference to the executable itself.
Rebuilding from source requires Visual Studio 2010 or later (VS Express Editions work too)
