A.D. Kent commented on PDFBOX-2195:
-----------------------------------
It would appear that the Tahoma,Italics (while an issue) was a bit of a red
herring. I believe the missing text on p10 was due to the following code that
was being used to scale:
{code}
PDPage page = (PDPage)pages.get(i );
PDRectangle cropBox = page.findCropBox();
PDRectangle newCropBox = new PDRectangle();
newCropBox.setLowerLeftX(cropBox.getLowerLeftX() -
(cropBox.getWidth()-cropBox.getWidth()*scale)/2);
newCropBox.setLowerLeftY(cropBox.getLowerLeftY() -
(cropBox.getHeight()-cropBox.getHeight()*scale)/2);
newCropBox.setUpperRightX(cropBox.getUpperRightX() -
(cropBox.getWidth()-cropBox.getWidth()*scale)/2);
newCropBox.setUpperRightY(cropBox.getUpperRightY() -
(cropBox.getHeight()-cropBox.getHeight()*scale)/2);
page.setCropBox(newCropBox);
PDFStreamParser parser = new PDFStreamParser(page.getContents());
parser.parse();
List<Object> tokens = parser.getTokens();
tokens.add(0,new COSFloat(scale));
tokens.add(1,COSInteger.ZERO);
tokens.add(2,COSInteger.ZERO);
tokens.add(3,new COSFloat(scale));
tokens.add(4,COSInteger.ZERO);
tokens.add(5,COSInteger.ZERO);
tokens.add(6,PDFOperator.getOperator("cm"));
PDStream newContents = new PDStream( document );
ContentStreamWriter writer = new ContentStreamWriter(
newContents.createOutputStream() );
writer.writeTokens( tokens );
newContents.addCompression();
page.setContents(newContents);
{code}

> Attempting to convert a PDF to image using latest 2.0.0 from SVN. PDF
> utilizes Tahoma, Tahoma,Bold, and Tahoma,Italic (non-embedded). Upon calling
> PDFRenderer.renderImageWithDPI, I get the following output:
> Jul 08, 2014 9:50:01 AM org.apache.fontbox.util.SystemFontManager
> findTTFontname
> WARNING: Font not found: Tahoma,Italic
> Resultant image is missing text where Tahoma,Italic is used. Have also
> reverted to 1.8.6 and used PDPage.convertToImage with same results.
