Fix EXIF code to prevent an overflow of the ifdstack array by one entry.

2004-10-23 Chris Madison <madisonblu@hotma...>

The -fx power operator changed to ^ and xor is : because it's not used very often. The bitwise operators &, |, and ^ have their operands multiplied by MaxRGB and the result divided by MaxRGB. The <, >, and = operators return 1 if true, 0 if false (e.g. for the threshold operation (u > .5), solarize (u * (u < .5 | u = .5) + (1 - u) * (u > .5)) (suggested by Gabe).

2004-10-22 Chris Madison <madisonblu@hotma...>

A bezier with no current point must assume assume the first control point is coincident with the current point (e.g. M100 400l590 259s36 12 61 12).
Fix ExpandFilenames() to not expand glob expressions if they are an option parameter.

The mogrify command parsed the -compress option but failed to set the compress member of the image_info structure.

2004-10-03 Cristy <yarrow@image...>

Add methods PaintOpaqueImage() and PaintTransparentImage() and deprecated OpaqueImage() and TransparentImage(). These methods are similar except they accept CMYK images in addition to RGB.

Correct another problem with PSD and group layer-- if the group layer is not visible, all the layers of the group should be not visible.

2004-09-29 Chris Madison <madisonblu@hotma...>

Converting images to Postscript larger than a Postscript page no longer produces an incorrect bounding box.
Return degrees, not radians, for asin(), acos(), and atan() in FxImage() (bug report by cerv@iue.tu...).

2004-09-14 Chris Madison <madisonblu@hotma...>

Fixed a dependancy ordering problem in the top-level Makefile.

2004-09-14 Steve Turner <norseman@first...>

Changed the I variable to image in coders/mat.c. It appears I is defined in the Slackware header files and it caused a compile error.

2004-09-13 Chris Madison <madisonblu@hotma...>

Some Postscript files were not translated properly when read.
DestroyImage() was previous void, now it returns (Image *) NULL to force the image to a known value and to detect logic errors in the program (any reference to image after it is destroyed will cause a fault). Other destroy methods will be changed in this manner as well. Note, this change will not affect existing programs that rely on these methods.

2004-09-13 Bengt-Arne Fjellner <Bengt-Arne.Fjellner@ltu.s...>

Fixed bmp.c so Imagemagick can read RLE4 coded bmp.

#define __attribute__ leaks outside the scope of a single header file, thereby killing any __attribute__ settings in the following code.

2004-08-30 Chris Madison <madisonblu@hotma...>

The default -module option operates in the HSB colorspace. You can operate in the HSL or HWB colorspace by using the -colorspace option (e.g. -colorspace HSL -modulate 100,130).

2004-08-30 Sebastien <sc5@herme...>

Images are not created when we receive a SVG error so an attempt to set the image title or comment caused an assertion exception.

2004-08-28 Cristy <yarrow@image...>

The DrawingWand DrawComposite() takes a wand rather than an image.

2004-08-28 Chris Madison <madisonblu@hotma...>

Add SetImageProgressMonitor() and SetImageInfoProgressMonitor() to the core API and MagickSetProgressMonitor() to the Wand API. These methods permit you to pass client data which is not permitted with the deprecated SetMagickMonitor() method.

2004-08-26 Glenn Randers-Pehrson <glennrp@glenn...>

avoid libpng-1.2.6 bug by setting PNG_HAVE_IDAT flag.

Prevent buffer overruns when decoding runlength-encoded images in the BMP format.

2004-08-19 Cristy <yarrow@image...>

Images with less than 256 unique colors, retain the exact colors. Previously some close colors were merged (e.g. 253 and 255 were averaged to 254).
Added -repage option, like -page but it acts as an image operator rather than a setting.

2004-08-04 Cristy <yarrow@image...>

PNG vulnerability fix.
Added YCbCr coder for raw Y, Cb, and Cr samples.
Fixed the -fx option operator precendence problem (+ and - should be the same precendence).

2004-07-23 Cristy <yarrow@image...>

Rare memory corruption due to a JPEG comment (bug report by brundlefly76@hotma...).

2004-07-19 Cristy <yarrow@image...>

The PerlMagick Evaluate() method no longer fails with an assertion error.
Restore -dSAFER for a more secure Ghostscript invocation. The downside is we must copy the Postscript file to a temporary file otherwise we get a the ocassional invalidfileaccess fom Ghostscript.

2004-07-18 Chris Madison <madisonblu@hotma...>

Do not report image depth unless the -verbose or -format %z option is used with the identify program.

2004-07-11 Cristy <yarrow@image...>

Sync pixel cache when cloning an image-- just in case someone clones an image clone and accesses pixels with AcquireImagePixel() instead of GetImagePixels().

2004-07-09 Glenn Randers-Pehrson <randeg@alum.rpi.edu>

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.

Fixed SVG-path-implementation for elliptical arcs for angle < 45° and the sweep-flag is 1 (bug repored by Juergen).
Fixed PerlMagick memory leak for corrupt TIFF images.
MagickBooleanType changed from unsigned int to an enum for stronger type checking. This should not affect the C API, however, for the C++ API you can no longer use `bool' instead of MagickTrue/MagickFalse for the methods that require a MagickBooleanType.

2004-06-23 Suryakant Patidar <surya_iiit@lyco...>

Add copious usability features to the animate program.

2004-06-22 Chris Madison <madisonblu@hotma...>

Add support for compositing pixels in the CMYK colorspace.

2004-06-20 Anthony Thyssen <anthony@griff...>

Added checkerboard background to display/animate X window to assist in visualizing transparent images.
The configure script now automatically enables OS features by selectively setting defines such as XOPEN_SOURCE, _POSIX_C_SOURCE, etc.
Added anonymous memory-mapping to the pixel cache. This makes it possible for memory to be returned to the system after the image is destroyed.

2004-05-31 Good Will <pu@dr...>

Fixed a bug in EnhanceImage() that incorrected shifted edge pixels.

2004-05-26 Alexandra Christini <alexandra@image...>

The active_list variable must be reset when a list is destroyed.

2004-05-18 Cristy <yarrow@image...>

Introduce MagickBooleanType and MagickStatusType types of unsigned int. These types are 100% compatible with the existing API but removes ambiguity. Previously we got complaints that users did not realize that a return value of unsigned int in most cases meant a binary value (True/ False). MagickStatusType is used for methods that return a bit mask.
Introduce MagickFalse and MagickTrue while we deprecate True/False.

2004-05-18 David Strobach <strobach@exec...>

Don't open a loadable module if its already open.

2004-05-14 Cristy <yarrow@image...>

Most Wand methods return an `unsigned int' where True indicates success and False indicates an error. We enhanced these methods to return MagickBooleanType and MagickTrue/MagickFalse to make it less ambiguous. Note these changes are 100% compatible so existing Wand calls will continue to work as written.

2004-05-14 Eli Barzilay <li@barzi...>

DrawSetStrokeDashArray() now respects the number_elements argument.

2004-05-12 Cristy <yarrow@image...>

Since the WMF coder has Wand dependancies we only enable this coder when both WMF is available and module support enabled.

2004-05-08 Daniel Kobras <kobras@debia...>

When an unknown property is encountered in the XCF coder, it enters a bogus loop that never terminates.

2004-05-06 Cristy <yarrow@image...>

Various modules in coders/ require external libraries (bug report from kobras).
PerlMagick's QueryFontMetrics() incorrectly reports `unrecognized attribute'` for the `font' attribute (bug report from Arfune).

2004-05-05 Cristy <yarrow@image...>

Fixed temporary file resource limit leak in RelinquishUniqueFileResource().

2004-04-19 Cristy <yarrow@image...>

ConvolveImageChannel() incorrectly initialized non-selected channels to 0.
Prep shared memory segments to automatically destroy itself in the event of a process kill (see http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=207379).

2004-04-19 Cristy <yarrow@image...>

ConvolveImageChannel() incorrectly initialized non-selected channels to 0.

2004-04-15 Cristy <yarrow@image...>

Added Cisco IP phone image format (write only).

2004-04-15 Alexandra Christini <ally@image...>

ImageMagick 6.0.0 released.

2004-04-10 Cristy <yarrow@image...>

Updated the dot coder to use the new graphviz 1.12 API.
The next/previous fields of the configuration structures (magick_info, type_info, etc.) are deprecated, instead use the Get???InfoList() method (e.g. GetTypeInfoList()).

2004-04-07 Cristy <yarrow@image...>

ColorFloodfillImage() with FillToBorder option stopped working in 6.0.0. Fixed now (bug report by Tim Hunter)..

2004-04-05 Cristy <yarrow@image...>

GetColorInfoList() returns an array of ColorInfo structures. Also added similiar methods for each of the ImageMagick lists (e.g. magick, delegate, etc.).

2004-03-22 Cristy <yarrow@image...>

Frame decorations are opaque if the matte color is opaque.

2004-03-15 Cristy <yarrow@image...>

Added CombineImages() to combine several grayscale images into a single image (e.g. convert -channel RGB image.R image.G image.B -combine logo.png).

2004-03-08 Cristy <yarrow@image...>

Added EvaluateImageChannel() method to the API. Use it to apply an an arithmetic, relational, or logical operator to an image. These operations can be used to lighten or darken an image, to increase or decrease contrast in an image, or to produce the "negative" of an image.

2004-03-07 Cristy <yarrow@image...>

Added a pixel iterator to the MagickWand API (suggested by Kyle Shorter).

2004-03-05 Teemu Ikonen <tpikonen@pcu.h...>

fixed the Matlab file reader read also files written in little-endian architectures.

2004-02-10 Alexandra Christini <achristini@bigpl...>

Reset errno in PerlMagick constant() method.

2004-02-20 <yarrow@image...>

Added `O' for importing/exporting pixels. `O' is the image opacity the eqiuvalent of MaxRGB-`A' (suggested by Dave Welton).

2004-02-04 Cristy <yarrow@image...>

Added the -posterize option to reduce the image to a limited number of color levels.

2004-02-15 Cristy <yarrow@image...>

Added the -splice option to splice the background color into an image (suggested by Anthony Thyssen).

Added -clone, -remove, -splice, and -swap as options to the convert program to enhance image list manipulation (suggested by Anthony Thyssen).

2004-02-05 Anthony Thyssen <anthony@griff...>

Expand the range of -dissolve to go from 0 to 200. That is values 0 to 100 slowly dissolve the overlay onto the background. But then values 100 to 200 slowly dissolve the background away until it is just the source image on top of a clear canvas the size of the original background.

2004-01-30 Cristy <yarrow@image...>

Added -separate to the convert program to separate a channel from an image and return a grayscale image (suggested by Anthony Thyssen).

2004-02-02 Glenn Randers-Pehrson <randeg@alum.rpi.edu>

coders/bmp.c: fix potential use of uninitialized data.
coders/png.c: fix potential use of uninitialized data.

Fixed a number of Magick Wand nits as reported by Rolf in the MagickWand discussion group (http://studio.imagemagick.org/magick/viewforum.html?f=6).
Added explicit option grouping to the convert command, for example, convert $ 1.png 2.png -append $ $ 3.png 4.png -append $ +append image.jpg (suggested by Anthony Thyssen).
Option -draw image respects gravity (suggested by Anthony Thyssen).
Text annotate respects gravity (suggested by Anthony Thyssen).
Add latest TIFF library to ImageMagick Windows distribution.

2003-12-22 Glenn Randers-Pehrson <glennrp@image...>

Added JPEG Quality, JPEG Colorspace, and JPEG Sampling factors to the "identify -verbose" report. Added "-define jpeg:preserve-settings" flag. If this is set, and the input and output formats are both JPEG, the input quality is used to compress the output file. Also, if the colorspace was not changed, the same sampling factors are used for compression.

2003-12-16 Marek Scholaster" <Marek.Scholaster@sezna...>

ResizeImage() parameter "filter" is never used.

2003-12-16 Ron Stanonik <stanonik@cogsc...>

Converted composite operators to inline methods in magick/composite.c.
Accept floating point image sizes (e.g. -geometry 1662.179324x2079.019558).
Added QueryMagickColor() to define CMYK colors. First use is with the XC image format (e.g. -size 100x100 xc:'cmyk(100,100,100,50)');

2003-11-18 Cristy <yarrow@image...>

Get EXIF data with $im->Get('%[EXIF:*]') in PerlMagick.
Added the -orient option to set the image orientation.
Postwww/PDF once again respects the image gravity attribute.

2003-11-16 Cristy <yarrow@image...>

To write an image clip mask, use the CLIP: coder.
Added GetImageExtrema() and GetImageChannelExtrema() to return the extrema for an image or image channel.
Added GetImageMean() and GetImageChannelMeand() to return the mean and standard deviation for an image or image channel.

2003-11-01 Lars Ruben Skyum <lars.skyum@stibo.com>

coders/jpeg.c: changed to not write gray CMYK images as grayscales. That would not be a valid optimization.
magick/color.c (IsGrayImage, IsMonochromeImage): Changed to never return true for CMYK images. Separated images get wrong colors when optimized to grayscales based on what these two functions return. Gray and CMYK are two different color spaces.
magick/nt_feature.c (NTIsMagickConflict): changed to accept colon as part of the magick string, consistent with the way the function is used.
magick/utility.c, magick/utility.h (ExpandFilenames, GetPathComponent): Fixed filename glob expansion. Added handling of filename prefix-magick and sub-image specification to GetPathComponent. Sub-image specification takes precedence over any filename patterns.

2003-09-30 Glenn Randers-Pehrson <glennrp@image...>

In the Q8 configuration, the bmp decoder was scaling 5-5-5-bit and 5-6-5-bit colors slightly incorrectly when decoding 16-bit BMPs, as well as when decoding 8-8-8-8-bit colors in 32-bit BMPs.

2003-09-26 Cristy <yarrow@image...>

Applied changes to get the current ImageMagick 5.5.8 beta sources compile on a Mac with Codewarrior 8.3.

2003-09-21 Cristy <yarrow@image...>

Image profiles are now conveniently handled with a hashmap structure. The color_profile and iptc_profile members of the Image structure are still maintained for backwards compatibility, however, we encourage you to use the new PutImageProfile(), GetImageProfile(), and DeleteImageProfile() methods.

2003-09-20 Cristy <yarrow@image...>

Error messages are enhanced to give greater detail. Use -debug Exception to trace the source location of an error.

2003-09-18 Lars Ruben Skyum <lars.skyum@stibo.com>

coders/ps3.c: Major update of the PS3 coder. The coder now creates much smaller files for bilevel, gray, and colormapped images. Compression and image type is now separated so they may be combined independently. Any alpha channel is separated into a separate mask so it's possible to mask bilevel, gray, colormapped, rgb, and CKYK images. You may also mask a JPEG compressed PS file for instance. Clipping masks created from a photoshop clipping path with -clip option is converted to a corresponding postscript clipping path. New functions need comment headers.
magick/attribute.c: Added TracePSClippingPath for creating a postscript clipping path from a Photoshop clipping path.
magick/image.c: ClipPathImage now stores the name of the clipping path in the mask image filename so that it is remembered and may be used for creating a postscript clipping path for postscript output.

2003-09-16 Cristy <yarrow@image...>

There is a new ImageMagick license (see http://www.imagemagick.org/www/license.html). It is a W3C-style rather than BSD-style license to address the frequently-asked-questions about what the license permits you to do. It makes it more clear that you can do pretty much whatever you want with ImageMagick as long as you don't claim your wrote it.

2003-09-12 Cristy <yarrow@image...>

Created a number of new header files to localize exported methods.
Updated source files to minimize the number of lint warnings.

2003-09-01 Cristy <yarrow@image...>

Reworked configuration file logic to load files from the current directory, at MAGICK_HOME, or at ~/.magick before the system versions of the configuration file. This allows a user to define private fonts in ~/.magick/type.xml, for example.

2003-09-01 Cristy <yarrow@image...>

Color was inverted when writing OTB monochrome images.
Add image histogram methods to C, C++, Perlmagick, and MagickWand API.

Fixed "Draw transparent color on background image without alpha" bug (bug report by Anthony Thyssen).
-fuzz now accept negative values.

2003-07-17 Lars Ruben Skyum <lars.skyum@st...>

support for grayscale color profiles. You may now convert to/from CMYK or RGB from/to grayscale with a grayscale profile. This is what Photoshop does when it creates grayscales from color images or makes true color images from grayscales.
any alpha channel is now maintained across colorspace conversions. It was previously lost in the conversions.
colormapped images may now be profiled with a color profile. They were previously passed through unchanged.
improved error handling. Any invalid colorspace / color profile combination is now catched in ImageMagick before LCMS gets a chance to catch the same error. LCMS will exit() the program the hard way if it catches such an error. ImageMagick clean-up routines will now be performed on exit.
support for the two remaining colorspaces, YCbCr and LUV, for which there is support in both ImageMagick and LCMS (or ICC 3.4, really). Profiles using other ICC 3.4 colorspaces not supported by ImageMagick will now properly throw an exception before LCMS exit's the application.
