Conversions with ICC Color Profiles
PDF2IMG honors calibrated colorspaces in PDF files when output color management is in effect, and will write target ICC profiles to TIF, JPEG, PNG, or BMP output files.
Color management can be suppressed using either the nocmm command line option or the pdf2img_set_colormanagement() API call.
For non-calibrated spaces, PDF2IMG will use the defaults provided by the Adobe PDF Library for conversions, depending on the colorspace.
Default Conversion Color Profiles
