Well, IM6 managed to identify the file correctly. I don't know IM internals but if it also tried the raw (DNG) module first, then it was able to fall back and try other modules in case that module was not able to handle the file. Specifically, if a delegate program doesn't even exist - shouldn't the ...

IM7 seems to delegate RAW file processing to ufraw-batch. If that program fails, IM refuses to process any .raw file, even if it is an incorrectly named TIFF or JPEG. IM6 identified such files correctly as TIFF/JPEG. The behaviour is the same regardless whether ufraw-batch fails to process the file ...

This applies to any TIFF tag with variable length. Here ist a simple EPS file that causes the error (0 byte 8bim profile) when converted to TIFF: %!PS-Adobe-2.0 EPSF-2.0 %%BoundingBox: 0 0 247 175 %%BeginSetup %%EndSetup %%EndComments %%BeginProlog 28.346000 -28.346000 scale -3.450000 -8.550000 ...

libtiff doesn't seem to like zero-length custom tags such as Photoshop or Microscope: convert: ./123770.tif: Null count for "Photoshop" (type 1, writecount -3, passcount 1). `_TIFFVSetField' @ error/tiff.c/TIFFErrors/562. Since this is a TIFFError, convert exits with a nonzero return code, although ...

The combination of -dFirstPage..-dLastPage and -dEPSCrop leads to an invalid command line: "/opt/local/bin/gsx" -q -dQUIET -dSAFER -dBATCH -dNOPAUSE -dNOPROMPT -dMaxBitmap=500000000 -dAlignToPixels=0 -dGridFitTT=2 "-sDEVICE=pam" -dTextAlphaBits=4 -dGraphicsAlphaBits=4 "-r305x305" -g2402x1572 ...

Thanks for the quick reply.

Here is a patch I made that works for me: http://www.rw-it.net/public/37724/patch ... iff.c.diff

Hi, there seems to be a problem when converting TIFF files when the source contains the Photoshop ImageSourceData tag (37724). I've used a command line like this (IM 6.7.2.0) to compress a TIFF file: convert -compress JPEG source.tif destination.tif Reading the input file shows the usual warnings ...
