Tilman Hausherr closed PDFBOX-5971. ----------------------------------- Resolution: Not A Problem Ok, I'm closing this one as well. Good luck and keep us updated! > Degraded quality on macOS when dpi is not provided > -------------------------------------------------- > > Key: PDFBOX-5971 > URL: https://issues.apache.org/jira/browse/PDFBOX-5971 > Project: PDFBox > Issue Type: Bug > Affects Versions: 2.0.33, 3.0.4 PDFBox > Environment: openjdk 11.0.26 > macOS 15.3.1 > Reporter: Tres Finocchiaro > Priority: Major > Attachments: image-2025-03-07-13-34-55-860.png, > image-2025-03-07-16-07-14-939.png, minimal_example_TYPE_INT_RGB.png, > pb_usps_sample-1.pdf > > > When providing a `-dpi` to PDFBOX: > {quote}Render into intermediate image with specific dpi and then print. Use > -1 for automatic detection of printer resolution. > {quote} > When printing to a 203 DPI printer on macOS, the quality differences are > quite different, with `-dpi 203` being significantly better quality. This > issue was originally discovered in PDFBOX-5967 due to a downstream usage > preferring `-dpi 203` for some older JDK versions due to a hard-crash > (PDFBOX-2682). > > Good: (with DPI) > {quote}{{java -jar ~/Downloads/pdfbox-app-2.0.33.jar PrintPDF -dpi 203 > -noColorOpt ~/Downloads/pb_usps_sample.pdf}} > {quote} > Not as good: (without DPI) > {quote}{{java -jar ~/Downloads/pdfbox-app-2.0.33.jar PrintPDF -noColorOpt > ~/Downloads/pb_usps_sample.pdf}} > {quote} > * I understand that this may be a result of something happening at the > OS-level. If this is the case, any guidance as to how to isolate and provide > a bug report for openjdk is greatly appreciated. > * If there's a workaround that can be used as a stop-gap leveraging the > PDFBOX API, that would also be greatly appreciated. > > [^pb_usps_sample.pdf] > !image-2025-03-07-13-34-55-860.png! > -- This message was sent by Atlassian Jira (v8.20.10#820010) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@pdfbox.apache.org For additional commands, e-mail: dev-h...@pdfbox.apache.org
