- General
- =======
- This is a library for manipulating (non-geospatial) images in GRASS GIS.
- The images2*.py files are a part of visvis library [1], specifically
- visvis.vvmovie. The files are from the visvis-1.8 version.
- [1] https://code.google.com/p/visvis/
- Changes to visvis
- =================
- In images2avi, the image format for temporary files is changed
- from JPG to PNG, to improve the resulting AVI. This makes the size larger,
- however the JPG format is unsuitable for maps in general.

- Questions
- =========
- Should we make the visvis files PEP8 compliant? This would make
- merging of possible changes from visvis more difficult.
