Leaving aside the viability of creating profiles from 16 bit reference data with i1Profiler, several folks have sent me emails or PMs about how to create targets with ImageMagick. I split the target into however many rows are needed. Each row is a separate image file.
First, create an image with the color data from the first patch in the row:
convert -size 100x100 xc:"rgb(100.0%,10.5%,0.0%)" -depth 16 Row-1.tif
This makes a single patch of 100x100 pixels (obviously you can adjust as needed). Color values are expressed as percentages. RGB of 0 = 0%, 255=100%, everything else lies in between.
We then add the next patch to the right side of the image:
convert Row-1.tif -background "rgb(0.0%,100.0%,98.9%)" -gravity east -splice 100x0 -depth 16 Row-1.tif
Continue on until the row is filled out. Repeat for the remaining rows. Scripting is your friend - bash, powershell, VBA - use whatever you are familiar with.
The individual rows can be combined with:
convert Row-1.tif Row-2.tif Row-N.tif -append FinalTarget.tif
The "-append" option combines all images into a single stacked column with N rows. If you are combining columns, use +append. The
montage command gives precise control over pasting together images; e.g. you want to tile them together in a pattern.
