Hello,
I have a big context source file which contains pictures from different
sources. The problem is, that there are some pictures the context cannot
process. It displays an error message and ends. I run the context from
another script in batchmode. After finishing, the context creates a PDF
file, which contains this problematic picture but the pdf is broken. It
does not have numbers in the table of contents and it is not arranged by
setup.
Here is a minimal example:
\starttext
\externalfigure[
http://cdn-locations-images.tripomatic.com/img-poi1295-5ZTynx-s.jpg][width=26.5mm
]
\stoptext
When I run the context, it prints:
! Dimension too large.
system > tex > error on line 1 in file a.tex: Dimension too large
...
1 >> \starttext
2 \externalfigure[
http://cdn-locations-images.tripomatic.com/img-poi1295-5ZTynx-s.jpg][width=26.5mm
]

\firstofoneargument #1->#1
Because I have several thousands pictures, it is impossible for me to
correct them all. Is it somehow possible to run the context so that it
ignores the problematic pictures?
Thank you
Pavel Dohnal

It's an image that could be correct, but TeX cannot manage it. It has 240x160 pixels and 1ppi, so it's 6,096 meters x 4,06400meters and 6 meters are too much for TeX (which still has its limits around 5meters) It's ok to print poster maybe, but then TeX is not the right tool. -- luigi ___________________________________________________________________________________ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / http://www.ntg.nl/mailman/listinfo/ntg-context webpage : http://www.pragma-ade.nl / http://tex.aanhet.net archive : http://foundry.supelec.fr/projects/contextrev/ wiki : http://contextgarden.net ___________________________________________________________________________________ ^ permalink raw reply [flat|nested] 14+ messages in thread

(Brr. I hate inches. Disgusting, Mars-mission-wrecking way of measuring things.) Here is some pseudocode. You'd still need a way to get image.width_in_pixels and image.dpi from the image; I daresay either `convert` or `exiftool` can do the job.

Is this solved already? the latest beta clips ... something: local maxdimen = 2^30-1 function img.check(figure) if figure then local width = figure.width local height = figure.height if height > width then if height > maxdimen then figure.height = maxdimen figure.width = width * maxdimen/height end elseif width > maxdimen then figure.width = maxdimen figure.height = height * maxdimen/width end return figure end end so it's taken care of (in principle the img library is right in handling > maxdimen dimensions as lua has no such limit) Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | voip: 087 875 68 74 | www.pragma-ade.com | www.pragma-pod.nl ----------------------------------------------------------------- ___________________________________________________________________________________ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / http://www.ntg.nl/mailman/listinfo/ntg-context webpage : http://www.pragma-ade.nl / http://tex.aanhet.net archive : http://foundry.supelec.fr/projects/contextrev/ wiki : http://contextgarden.net ___________________________________________________________________________________ ^ permalink raw reply [flat|nested] 14+ messages in thread

The problem is perhaps that its resolution is a bit low so that you are limited as far as its size of the picture is concerned. But 4x4 cm would give an acceptable result, I think. (I tested it and the result is quite OK.)
