  -p, --png              encode images to PNG instead of JPEG
  -b, --bmp              encode images to 4-Bit BMP instead of JPEG
  -w, --width=0          image width
  -h, --height=0         image height
  -q, --quality=75       JPEG image quality
  -n, --norgb            do not convert images with RGB colorspace
  -i, --interpolation=1  0=NearestNeighbor, 1=Bilinear, 2=Bicubic, 3=MitchellNetravali, 4=Lanczos2, 5=Lanczos3

  -o, --outdir="."       output directory
  -m, --size=0           process only files larger then size (in MB)
  -r, --recursive        process subdirectories recursively
  -v, --quiet            hide console output

Args:
  <args>  filename or directory

Examples

cbconvert --recursive --width 1200 --size 60 /media/comics/Thorgal/

Rescale images to 1200px for all supported files found in directory with size larger then 60MB.

cbconvert --bmp --outdir ~/comics /media/comics/Garfield/Garfield_01.cbz

Convert all images in archive to 4bit BMP image and save result in ~/comics directory. BMP format is uncompressed, for black&white pages very good choice. Archive size can be smaller 2-3x and file will be readable by comic readers.

cbconvert --interpolation=5 --outdir ~/.thumbnails/normal --thumbnail /media/comics/GrooTheWanderer/

Generate thumbnails by freedesktop specification in ~/.thumbnails/normal directory, Lanczos3 algorithm is used for resizing.
