Just leaving this link just in case it would be useful to anyone else who also wants to have a go at implementing SCoA: https://github.com/caxapyk/capt_lbp810-1120 It's a fork of the...

> No, as say @agalakhov its don't realizing SCoA compression Oh, I didn't know that Nicolas' driver wasn't complete :disappointed: For those coming from Google or the future: see also...

:point_right: EDIT: the [SCoA specs now have a page in my wiki](https://github.com/mounaiban/captdriver/wiki/SPECS:-SCoA-Specifications), please check it out for more info. @agalakhov I have been trying to understand SCoA for the past...

@ra1nst0rm3d In the Copy command, `length` means the _number of bytes in the input, after the opcode, to copy to the output_. Sorry for the unclear wording; I'm trying to...

I'll just document this here before writing up a wiki page: ### Generating SCoA/CAPT print data using ``captfilter`` To generate a ready-to-send SCoA-compressed raster from a Portable Grey Map (PGM)...

@agalakhov Just a quick question: do you flip bytes in the SCoA bitstream? Or is it just the command and the packet size that's flipped to little endian? For example,...

We may have discovered a few more things about the SCoA format, particularly a few new opcodes and the usage of the line buffer. #### Long Repeat only Command `101aaaaa...

@agalakhov Thanks, I understand it now that there's nothing to flip in the bitstream/payload.

@ra1nst0rm3d Well done, you have just drawn a complete blank line across an A4 sheet! :100: Also: `bf b8 ff bf b8 ff aa b0 ff` `41 41 41 41...

I have confirmed the existence of the buffer pointer seek/skip opcode. There are three forms: #### Short seek: skip right up to 7 bytes, place a single byte A `0x0b00001aaa`...
