Sorry, that was too quick…

Hi,

currently, ConTeXt can’t use tiffs directly, but it uses Graphicsmagick to convert tiffs to pdf on the fly. However, as it seems, graphicsmagick is producing invalid pdfs.

For every included tiff I have something like this in the log:

luatex warning  > pdfe: invalid 11 0 R object at offset 573751

luatex warning  > pdfe: invalid 11 0 R object at offset 629127

The offsets are different, but it’s always this «invalid 11 0 R object».

This bug has been known for quite some time, but it apparently hasn’t been fixed yet: https://sourceforge.net/p/graphicsmagick/bugs/513/

Converting the tiffs to jpeg circumvents the problem. Would it be an option to convert tiffs to jpegs instead of to pdf? (Is that already possible?)

Best,

Denis
