TI1, TI2, CSV and printtarg target files for SpyderPrint Targets

[knowing]

Just to let everyone know,
If you or anyone are interested in the color data for SpyderPrint targets, then I a script "read_image_patch_colors" that extracts color values from a rectangular grid of color patches in an image, computes colorimetric values (RGB percentages, XYZ, Lab), applies row/column labeling rules, and writes three output files:

• ArgyllCMS .ti1 file
• ArgyllCMS .ti2 file
• CSV file (space-separated)

You can find the script here:
https://soul-traveller.github.io/read_image_patch_colors/

There is a folder "Example Targets Read" which contain most of the SpyderPrint targets, as well as the generated files. I have used it on the following targets:

• Expert Target (3-pages, 729-patches)
• Expert Target (large) (1-page, 729-patches)
• Expert Target Plus Grays (4-pages, 967-patches)
• EZ 729 Colors Plus Grays (9-pages, 996-patches)
• High Quality Target (1-page, 225-patches)
• High Quality Target Plus Grays (2-pages, 463-patches)
• LaserSoft Advanced Target (864 patches)

I have also updated the release in the link with many printtarg targets based on .ti1 files made for SpyderPrint and LaserSoft Advanced Targets.

Hope this is useful for you or anyone in the forum.

I made this as one step in a plan to try using SpyderPrint measurements, and then use the output for ArgyllCMS to create profiles. I am not there yet an not sure I will ever finish that work.

Let me know if any bugs or problems are found.

Cheers,
K
