Solomon Peachy 21bba6ea48 Minor doc updates 2024-06-04 21:32:40 -04:00
Solomon Peachy e44fbc2d0c lib70x: More fixes with respect to rewinding on the D80 
* Only the EK305 uses a 10-entry REV table; the rest only use 4
 * Implement logic for 4-entry REV table lookups
 * On the D80, if we have to switch to the ECPC table, we also
   need slow from SF to UF print speeds.
 2024-06-03 21:57:59 -04:00
Solomon Peachy 2fd196259b lib70x: Corrections with CP-D80 and rewind / superfine operation 
* Use of ecpc has nothing to do with rewindability
  * Libary lacks awareness of print speed so stay out of rewind decision

This is an API change, so bump the version.

Solomon Peachy 30557772c1 mitsud90: add csv data files for D90 family. 2023-12-21 20:45:27 -05:00
Solomon Peachy c0a9f7499c mitsud90: Add in a LUT for the D90, may be needed in panorama mode 
(The LUT needs to be done _before_ the panel split, so it can't be done
 in-printer)

Solomon Peachy afc7b18229 lib70x: Two bugfixs with respect to the CP9800 family 
1) WMAM structure wasn't being initialized properly
   * Incorrect coefficents on two data arrays
   * Incorrect source in a memcpy for a weight factor table
 2) Buffer overflow in the output work buffer because it was
    incremented by one ROW for each pixe.

Who knows, the printer family might even print properly now?

Solomon Peachy aaa63cac89 mitsu70x: Support Mitsubishi CP-K60DW-S "HG" media 
Apparently there's a "media subtype' field, and HG media needs a
different calibration data file.

Solomon Peachy e450d6f496 mitsud90: Initial support for the Fujifilm ASK-500 
Looks to be a near-identical clone of the CP-M1 series, albeit with
different color curves and no LUT.

Currently untested, as I don't know the USB VID/PID.  Gutenprint
support not yet committed.

size shrink on x86_64, for example)

Solomon Peachy 11d301e46b lib70x: Correct a subtle color correction bug 
Initialized the wrong data structure, causing faint ghosting in very light
areas closer to the start of the print/.

This was first reported on the K60 and EK305, but presumably affected
all members of the family.
