Re: [Podofo-users] Podofocolor error

[Matthew Brincke]

Hello Matt, hello all,

currently on encountering an unsupported color space, the information
about it is discarded, so no output file can be produced in that case.
I don't have time to rectify that currently, sorry.

Best regards, mabri

Hi,
I cannot tell whether it's related or not, but just in case, could you
try with the current trunk version [1], or at least apply this [2]
change to your 0.9.5, please?

Otherwise I've not much idea. Lua is an optional dependency, thus you
can compile without it too.
Bye,
zyx

[Podofo-users] Podofocolor error

[Matt S Rinc]

  Podofocolor (latest library compiled with no errors on Mac) gives me
this error when opening CMYK colorspaced PDF:

(it doesn't matter what parameters I call podofocolor with, e.g.
grayscale etc) 

  and gives me this error when opening RGB colorspaced PDF:

> ff_dummy.pdf

  Any help would be really appreciated. I doubt a C(++) program will
rescue me e.g. open a PDF, change colors in it and save it.
