# WARNING: PIL is required for all image mangling! # WARNING: PIL is required for all image mangling!
# 1.30 - Fixed an issue in OPF generation for device resolution # 1.30 - Fixed an issue in OPF generation for device resolution
# Reworked options system (call with -h option to get the inline help) # Reworked options system (call with -h option to get the inline help)
# 1.40 - Added some options for controlling image optimization
# Further optimization (ImageOps, page numbering cut, autocontrast)
# 1.41 - Fixed a serious bug on resizing when img ratio was bigger than device one
