[magick-users] Problems with compression in 6.4.2 Q16 (Debian)?

[Leigh Ahwai]

Hello,

I'm running LIBTIFF version 3.8.2 and I've checked the files mentioned
below and everything seems correct 
(NOTE: we have tiffconf.h instead of tiffconf-32.h).

Still can't get compression to work in 6.4.2

Any other thoughts or suggestions appreciated.

Here's what I found:
-------------------

magick-config.h
#ifndef MAGICKCORE_HAVE_TIFFGETCONFIGUREDCODECS
#define MAGICKCORE_HAVE_TIFFGETCONFIGUREDCODECS  1 #endif

tiffvers.h
#define TIFFLIB_VERSION_STR "LIBTIFF, Version 3.8.2\nCopyright (c)
1988-1996 

tiffconf.h
#define JPEG_SUPPORT 1
#define YCBCR_SUPPORT

Cheers,
Leigh Ahwai

Check magick-config.h.  Is MAGICKCORE_HAVE_TIFFGETCONFIGUREDCODECS
defined?
Check tiffvers.h and report the TIFFLIB_VERSION define.    Check
tiffconf-32.h and see if JPEG_SUPPORT and YCBCR_SUPPORT are defined.  If
one of these is not defined, ImageMagick assumes JPEG compression is not
available and defaults to NONE compression.
