Encoding options

Most of image viewers have no GUI for custom plugins, so you need an encoding option file. You can specify different options for 8-bit & 24-bit images. The line started with 24: indicates the options for 24-bit images, and 8: for 8-bit images.

Supported options (see: bpgenc):

• -q (0~51) set quantizer parameter (smaller gives better quality, default=29)
• -f (420|422|444) set the preferred chroma format (default=420)
• -loseless enable lossless mode (default=off)
• -m (1~9) select the compression level (1=fast, 9=slow, default=8)

Example:

8:-q 30
24:-q 25
