-----------------------------------
Resolution: Won't Fix
> PDFs with Bitmap Fonts are getting rendered poorly
> --------------------------------------------------
>
> Key: PDFBOX-3902
> URL: https://issues.apache.org/jira/browse/PDFBOX-3902
> Project: PDFBox
> Issue Type: Bug
> Reporter: Yannick Haser
> Attachments: 144dpi.jpeg, 432dpi_scaledDown.jpeg, test.pdf
>
>
> I have a problem with converting some special PDFs to JPEGs. Those "special"
> PDFs have a bitmap Font for their text-representation, after converting to
> JPEG the text is not readable.
> Converting the PDF to a higher resolution and scaling it down manually fixes
> that issue (Problem: Higher Converting Cost).
> The problem for the ticket is, that I'm not allowed to present those PDFs and
> I still cannot reproduce those perfectly.
> My best shot is the attached PDF.
> Problem-Setup:
> Converting the PDF to JPEG with 144 DPI.
> {code:java}
> BufferedImage image = renderer.renderImageWithDPI(0, 144, ImageType.RGB);
> {code}
> Fix-Setup:
> Converting the PDF to Jpeg with 432 DPI and scale it down with an external
> Scaling Algorithm.
