In P6 I’ve used thumbnails to make, for example, machinery spare-parts lists and sculpture catalogs, and assumed that this was a common way to output from Panorama.
When the same jpegs wouldn’t convert to PX usefully without at least doubling the image size (which still looked terrible although usually recognisable) I was mildly surprised that nobody had posted about the poor resolution. After Jim replied that the problem was insoluble, I wondered if the lack of comment was because nobody else used thumbnails – thanks Bill for confirming that there are at least two of us!
The screen grabs above were both made with the same tool, CleanShot, which produced much bigger images when transferred into the forum reply box, and I couldn’t exactly match the two sizes.
Below is a more accurate sizing (at least as seen on a MacBook Pro 16 screen) of PX output at 16 images to the A4 page, printed on an HP Color LaserJet Pro M453 on regular copy paper, photographed on iPhone 14. Each printed image is 47.5mm square, just under 2 inches (pretty big for “thumbnails”).
The type output is fine, the photos would make you weep.
I guess that just creates the question of what then is Apple doing in Preview that’s different than how the Apple image display object works?
I accept Jim’s word as final. I am posting in the hope of finding a long-run alternative to reverting to P6 (which outputs jpegs just as clearly as Preview).
