be used externally (will be pulled in automatically).

<LI> tests/Makefile.am (TESTS_TIFF_XFAIL_TESTS): EPT and PTIF tests
are expected to fail if libtiff is missing.

from -180 degrees to +180 degrees expressed as an argument of 0 to
2.0 (1.0 for no change). Note that this change also effects the

<UL>
<LI> magick/cache.c (ClonePixelCache): It appeared that cloning a

size_t. This would result in a truncated cache. The offset type
is changed from size_t to magick_off_t in order to avoid this.

<UL>
<LI> fix incorrect argument to png_set_keep_unknown_chunks().
</UL>
<p>
2004-08-07 David R. Linn <drl@vuse.vanderbilt.edu>
<UL>
<LI> www/formats.html: Titles for JNG and MNG were reversed.

</UL>
<p>
2004-08-02 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
<UL>
<LI> magick/image.h (Image): Changed type of 'colors' and 'depth'
members from type 'unsigned long' to 'unsigned int'. This change
is made because on 64-bit CPUs, 'unsigned long' is a 64-bit
type. The depth member is often used in switch statements. It is
not recommended to use 64-bit types in switch statements. The
maximum number of colors in the colormap is limited to 64K so a
64-bit type is not required.
</UL>
<p>
2004-08-01 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
<UL>
<LI> coders/tiff.c (ReadTIFFImage): Restore previous 8/16

pointer on some compilers, like VC++ and gcc. This is not the case
of Borland C++ Builder" - Thanks to Marti' Maria that have supplied me
this patched file: this will be part of the next lcms 1.14 which probabily
will be released on summer's end.
</UL>
<p>
2004-07-20 Mike Chiarappa <mikechiarappa@libero.it>
<UL>

<LI> BCBMagick: included jbig delegate library.
<UL>
<LI> Modified these files into directory BCBMagick: All\bcbMagick.mak;

<UL>
<LI> coders/bmp.c (ReadBMPImage): Removed if-test on reading
red_mask, green_mask, and blue_mask. These are only *valid*
under certain conditions, but they are always present in the
file.
</UL>
<p>
2004-07-08 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
<UL>
<LI> Enable LZW compression by default.
</UL>
<p>
2004-07-05 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
<UL>
<LI> coders/jpeg.c (WriteJPEGImage): Don't enable Huffman compression
for large images (> 16 Mpixels for the moment) in order to
conserve memory. When Huffman compression is enabled the entire
image is buffered in memory prior to encoding and writing
anything. Huffman compression is a method of eliminating
redundant data so when the Huffman compression is disabled, files
sizes will be larger, but otherwise the image is the same.
<LI> wand/magick_wand.c (MagickSetPassphrase): String was being
copied to a null pointer. Now memory is allocated as required
prior to a copy.<BR>
Ensure that all unimplemented functions return a proper error
report.

<UL>
<LI> magick/command.c (MogrifyImage): For -units, don't reset
resolution if units are undefined. Report an error if the -units
argument is not supported.
</UL>
<p>
2004-06-27 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
<UL>
<LI> magick/command.c (MogrifyImage): When setting image units, also
adjust existing image x_resolution and y_resolution so that
existing image resolution is not trashed.
(MogrifyImage): When re-sampling an image, report an error if the
image does not contain a valid resolution.
</UL>

<p>
2004-06-10 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
<UL>
<LI> configure.ac: Look for mozilla by default rather than netscape.
</UL>
<p>
2004-06-02 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
<UL>
<LI> magick/type.c (ReadTypeConfigureFile): Determine location of

<UL>
<LI> magick/module.c (InitializeModuleSearchPath): Evaluate and cache
module search path.<BR>
(FindMagickModule): Use cached module search path.
(OpenModules): Load all modules rather than just the modules in
the directory where the LOGO module is found. Besides allowing
user-provided modules in non-GraphicsMagick directories to be
loaded, this allows the "moby" shared build to load additional
modules via OpenModules.
</UL>
<p>
2004-05-28 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
<UL>

<p>
2004-05-23 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

MinGW.
</UL>
<p>
2004-05-22 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

<LI> version.sh (PACKAGE_CHANGE_DATE): Update release to 1.1Beta2.
<LI> magick/constitute.c (ReadImage): Ignore errors of type
ConfigureError when loading modules so that error report can still
report the familiar "No delegate for this image format" message

it was found. This is a compromise which reports useless messages
when the modules are not found at all, but I can't think of a way
around it.<BR>
<LI> magick/nt_base.c (NTSystemComman): Adjust
MsgWaitForMultipleObjects() arguments to wait for object to be

well as an input event received(TRUE). It seems that process
status changes do not result in an input event, so the call was
deadlocking.<BR>

<UL>
<LI> coders/tiff.c (TIFFMapBlob): Allow libtiff to access memory
mapped file (or BLOB in memory) directly. This provides a small

file, then be sure to remove the associated .cache file when
removing the .mpc file.<BR>

properly for this blob type.<BR>

be closed by the library (may be an externally provided file
descriptor).<BR>

keeps the input file from being closed.

<UL>
<LI> magick/cache.c (OpenCache): While allocating the pixel cache
from the heap, reserve enough memory to contain a full PseudoClass
image in order to reduce the chance that there will be a memory
allocation failure while processing the image. This also avoids
the possibility that the image pixels will be block-copied to a
new location due to heap memory fragmentation. If there is
insufficient heap memory (malloc() fails), then a disk-based pixel
cache will be used.<BR>
<LI> coders/wpg.c: Backed out Jaroslav Fojtik's patch from 2004-01-13
