Quick PDF has a feature to convert a PDF into an Image:

iNumPages := PDFLibrary.PageCount();
PDFLibrary.RenderDocumentToFile(300, 0, iNumPages, 0, 'H:\temp\quickpdf_testimage_6_new.bmp');

If this feature is executed the letters move (with some PDF sources) in each other. In the following there is a PDF and the resulting JPG:

PDF: http://www.baunetz.de/aip/2001/tunnel.pdf

No there is a problem: in the resulting Image the Letters move in eachother.

This PDF contains a font (OfficinaSans-Book) that is not embedded in the PDF so Quick PDF substitutes Arial instead which has thicker characters.

This is a common problem with PDF's and many PDF viewers. The best solution is to create the PDF with embedded fonts for any of the non standard fonts that are used in the PDF.

"This PDF contains a font (OfficinaSans-Book) that is not embedded in the PDF so Quick PDF substitutes Arial instead which has thicker characters."

Is there the possibilty to embed this OfficinaSans-Book into the pdf engine and force the QuickPDF to run PDFLibrary.RenderDocumentToFile with this specific font?

Hi!

Yes. Try AddTrueTypeFontFromFile
or AddTrueTypeFont:

Thx for your answer. With AddTrueTypeFont it didn't work.
It didn't use the font that i added even if i used the SelectFont command.
The result was always the same. Also the ReplaceFonts command didn't work.

I also found out that adobe / foxit use multimaster fonts if they don't find a font on the system. Do you have similar features (planed) in Quickpdf?

Edit:
I have found the following in the FAQ:
'No, it's not currently possible to change the font that a text object uses. The problem with changing the font that a particular text object uses is that in changing the font the height and width of the characters that use that font also change and can mess up the layout of the document.'

It would be easier just to install the font into Windows and the the PDF would render correctly.
