Hi, Graeme. I'm glad to see that ArgyllCMS is condiniously developing. Thank 
You for Your patience and our requests satisfying.
Now I ask a feature of the printtarg: rectangular patches of arbitrary size in 
arbitrary size boundaries.
While working and experimenting with CMS, I'm constantly (for years) dealing 
with the targets which patch size can vary from 5x5 to 15x20mm, with and 
without the spacers. I'm using ImageMagic "convert" utility to crop and resize 
Argyll targets into desirable format. But it's quite annoying to define crop 
and resize pixel values for every new case.
I'mÂproposingÂnew printtarg "instrument type", for example, -irp (Rectangular 
Patches) with parameters -b and -d:

printtarg -irp [-a1 -A1] -b6 -d6 -m0 -p90x140 -t300 -D Target

Which shouldÂgenerate the rectangular targets of 15x21 patches with spacers. 
The dimension of the target should accommodate given paperÂsize and the border. 
For given example I want to get 90x139.2mm images without any bordersÂand 
marks, just only with rectangular patches and 1/10 size spacers.
At this moment, after You've update the patch placement algorithm, there was no 
cases when chartread was able to misread different strips of different targets. 
So, I see no need at the moment to print any indexing on the targets. I'm using 
every square centimeter for theÂpatches. I hope it helps to "save the planet".
One more thing: canÂthe antialising between the patches while rasterizing into 
the TIFF be disabled? Filtered pixelsÂat theÂpathes boundariesÂdisturbs the 
target histogramm analyzing and leading to increaseÂof theÂsize of compressedÂ
Thank You for Your attention.

Best regards,
Nikolay Pokhilchenko.
