I have a picture made with PSP 18 in a scan of bw negativ film at a Canon 9000F Mark 2.
The jpg picture is OK in Irfan View. DPI = 1200 and 2145 x 1265 px.
When I make an import of this jpg to Scribus I get a hazy picture very small.
Then I made a pdf "print" from PSP, and save it as a page. Open the saved pdf again in PSP with 300 dpi. Cut it out of the page and save it as a jpg file. Now I can import without problems to Scribus.
Attachment: hca 1.jpg is the scan and positive picture from Canon, hca 1 ny.jpg is the picture made around the pdf print
