Paint Shop Pro file size limitations

I have been trying to open a very large DNG file using PSP. Its 6 images taken with a K-1 stitched together in LR6 to form a panorama. PSP won' open it. However the same 6 images stitched together using Microsoft ICE to produce an equally large file but a TIFF image can be opened.Their tech confirmed the problem and have a copy of the DNG file. They escalated it to the next level'. The versions I have used are PSP X9 and PSP 2018.

The latest news is and I quote from their email "Sorry, but please note that PaintShop Pro can only open file s up to 20,000 pixels. This is most likely the reason why your file cannot be opened."

It does not explain why it works with a TIFF file and 20,000 pixels seems ridiculously low. K-1 is 36 megapixels. what do you think, should I give up or get back to them again.

Probably won't work because it's a .dng file out of LR. Didn't know you could save to .dng

PS. IIRC there's also a max file size, 120MB (?). You'll have to go to the PSP forum for a correct answer on that.

Maybe they meant 20.000 pixels linear resolution:

20k * 20k = 400MP total, obviously less if aspect ratio is not square

I believe that is the case. I also suspect that the Adobe-generated DNG may also be at issue. DNG is not a universal RAW type in that generating source may influence tool compatibility. A good example might be a PEF converted to DNG by Adobe's DNG conversion tool or at import into Lightroom. That file is unreadable by the Pentax Digital Camera Utility (PDCU) software. Apparently the Adobe-generated files contain proprietary elements.

I replied to their email querying their 20 000 pixel figure, you guys could be right about it being 20k X 20k. I have also sent them the same panorama but as a TIFF image created by Microsoft ICE and will see what they say. It could well be the Adobe DNG file type
