YCbCr. Default YCbCr to Rec.709 if the transfer characteristic is

74
* coders/pcd.c (Upsample): Moved Upsample from gem.c to here since
71
75
PCD is the only user and it is not a general purpose function.
80
84
* wand/magick_compat.c (FormatMagickStringList): MagickExport since this
81

93
* coders/dpx.c (ReadDPXImage): Added support for dpx:swap-samples
87
94
define in order to handle files with Cb and Cr swapped. Fixed a
88
95
bug in the header reading which caused some valid files to fail to

116
* VisualMagick/magick/magick_types.h.in: Add patch for Ch.
109
118
* magick/command.c (TransmogrifyImage): Complete re-write of
110
119
mogrify file handling. Former version wrote to a temporary file
111
120
and then moved temporary file to replace original if necessary.
112
121
New version moves an existing writable file to a backup file with
113
tilde ('~') added to end of file name, writes to the final output
122
tilde (`~`) added to end of file name, writes to the final output
114
123
file name, and removes the backup file on success. The new
115
124
approach satisfies formats which embed the output name in the file
116
125
(e.g. the DPX format) and still works when the output file exists
131
140
* magick/attribute.c (GetImageAttribute): Add more general support
132
141
for retrieving wildcarded attributes so that an identify -format

177
190
* magick/colorspace.h (enum ColorspaceType): Decided that
178
191
GRAYColorspace should be reserved for full-range grayscale data
179
192
while Rec601LumaColorspace and Rec709LumaColorspace should be for
180
193
video colorspaces. Therefore, GRAYColorspace is no longer a
181
194
synonym for Rec601LumaColorspace.
182
196
* magick/colorspace.c: Added support for influencing Cineon Log
183
197
colorspace transformations via image attributes.
184
198

integer in order to reduce the amount of noise added by
186
200
transform table quantization.

* coders/psd.c (WritePSDImage): Ensure that output image is 8 or
188
203
16-bits regardless of specific image depth.
189
205
* coders/dpx.c: Added support for planar YCbCr 4:2:2.

240
symbols starting with 'X' so that they are prefixed with 'Magick'.
260
symbols starting with `X` so that they are prefixed with `Magick`.
241
261
This eases maintenance since it is almost impossible to understand

code which pretends to be the X11 libraries. The few programs
243
which use the GraphicsMagick 'X' functions will need to alter the

* magick/command.c (DisplayImageCommand): Don't invoke
246
267
XrmDestroyDatabase() to destroy the resource database associated

498
548
by Stefan v. Wachter <svwa-dev@mnet-online.de>. This error with
