Waldbaer Posted January 20, 2017 Share Posted January 20, 2017 Hi Serif, I currently run into a problem of false Resolution after following workflow: - open Scan 600dpi (.tif) - resize to 300dpi (¼ pixels, same print size) - save as Affinity Photo file - Export as JPEG As a result closing/opening the files I saved, the .afphoto has the correct 300dpi, but the .jpg has again 600dpi at the same pixel count (so it will be printed half as long on either side). I think that's a bug, isn't it? I'm using Photo 1.5.1 on a Mac with 10.10.5. I'd like to know if you can reproduce and address this. Thanks for your answer! Waldbär PS: Of course, I still appreciate any feedback on my topics (1, 2) concerning batch processing, too. Quote Link to comment Share on other sites More sharing options...
R C-R Posted January 20, 2017 Share Posted January 20, 2017 One reason this can happen is if you have "Embed metadata" enabled (in the "More" section of the export dialog) & the original file had a dpi values embedded in it. In that case, the original embedded dpi values are preserved.

Waldbaer Posted January 21, 2017 Author Share Posted January 21, 2017 Thanks for your fast response! OK, so it embeds obsolete dpi values as metadata which will be read as the actual dpi afterwards? Is there any benefit to this? Anyways thank you for the workaround, saving it without metadata will in fact save the correct resolution as a fast test showed.

R C-R Posted January 21, 2017 Share Posted January 21, 2017 It is up to you to decide if the original dpi values should be retained. Note that for web pages & just about anything else besides printing, the dpi values are irrelevant, & relevant for printing only if the printing software & print driver uses them.

Waldbaer Posted January 21, 2017 Author Share Posted January 21, 2017 You're right, in most cases I don't even notice the difference. Biggest problem: The Windows 10 printer driver does not support zoom/scaling but reads the dpi, so it's difficult to extract and/or print specific pages from the pdfs.
