v0.5

ass2bdnxml v0.5

Changes

• Add libimagequant to output palettized PNG images, required by some authoring suites. This is enabled by specifying --quantize (-q) followed by the maximum number of colours accepted (typically 255 for PGS).
• Add flag --rleopt (-r) to prevent the usage of palette entry zero. May fix the "Line could not be encoded" error seen on Scenarist.
• Change --split (-s) flag to parameter. 4 modes availables: {0: Disabled, 1: Vertical, 2: Vertical + opt. Horiz, 3: Both ("aggressive")}
• Add argument --offset (-o) to specify a TC offset to apply to all BDN timecodes.
• Add flag --negative (-z) to mark the TC offset specified with --offset as negative. Value warp-around is not implemented, use with care.
• Fix --par (-p) to be the real PAR and not 1/PAR.
• Add --splitmargin (-m) to specify a minimum margin between two crops to effectively split them. Argument format is VxH, where V is the minimum y axis difference, and H the minimum x axis difference. 'x' is a separator and is only required if H is provided. V can be provided alone. This argument greatly affects the behaviour of the split. It is very handy with the aggressive split mode --split 3.
