Ok, having thought more about this, I am maybe starting to get it. Could still use help.
I want to know how to check if the full resolution of a gimp image is preserved when I export to pdf.
When Gimp says my image is 6.88 inches wide, I guess that refers to the printing size -- not to how big the monitor makes the image look.
My monitor's own resolution is 141 px per inch. (15.6 inch monitor, 1920 x 1080 resolution).
So if I set the image resolution on a gimp image to 300 x 300 ppi, then when I view that on my monitor with Gimp at 100% zoom, an image that will print at 6.88 inches wide will appear on the monitor I suppose as (300/141) x 6.88 inches, which is about 14.6 inches visually on the monitor. That is roughly what I do see on my monitor with Gimp at 100% zoom (the 6.88 inch image appears 14.45 inches wide visually on my monitor). But when I export that image to pdf and open it in Adobe Acrobat at 100% zoom, and set Acrobat to 300 px/inch, the image is 18 inches wide, not 14.6.
Why is that? Thanks for any assistance.
