Moving from GhostScript to PDFTron for PDF rasterzation

[Support]

Q: I'm testing your PDF2image and PDFNet for OS X. Great products!

We use GhostScript but we have problems. We would like to change the rasterization engine.

About PDF2Image:

1) I have read all the documentation and I have not found references to color management when the engine rasterize from CMYK to RGB. There are any possibilities to consider the source profile/s in the PDF and convert for example all to sRGB?

2) From my test pdf2Image support also CJK fonts. Can you confirm?

3) If for any reason a font is not embedded in the PDF (completely of as subset) PDF2Image substitute with "some" default font?

----------------

A:

Color management is by default enabled when running pdf2image. It can be disabled with --nocms otpion.

You can also use --icc_rgb and --icc_cmyk to overide default ICC profiles used to represent device RGB and CMYK color spaces.

In PDFNet color management is controled with PDFNet.SetColorManagement() and PDFNet.SetDefaultCmy/RgbProfile().

➢ If for any reason a font is not embedded in the PDF (completely of as

➢ subset) PDF2Image substitute with "some" default font?

Correct. In case you don’t like default substitution you can provide your own font mapping using ‘--config’option. A sample XML config file is attached. In PDFNet the config file can be loaded using PDFNet.LoadConfigFile() or providing an explicit mapping via API (PDFNet.AddFontSubst - as shown in PDFDraw sample).

Yes, we support all fonts that are described in the PDF standard, including CJK fonts.
