100    format as well as the coderInfoList() template function to return
101    the list of coders which match a specification.
102
103  * User now may tell Blob updateNoCopy() what memory system (C or C++)
104    the memory was allocated from.  Used to assume the C++ allocator.
105    This resolves a bug on some platforms (e.g. Windows).

108    attenuate, image opacity.
109
110  * Added Image 'type' method (and STL typeImage()) to set image
111    representation type.
112

139  * Magick++ demo output looks like PerlMagick demo output again.
140
141(5.3.5)
142  * Default radius and sigma parameters were changed on the blur,
143    charcoal, emboss, and sharpen methods to match ImageMagick defaults.
144  * Fixes to Magick++ demos to restore appearance.

226  * Fix text annotation bug which did not allow spaces in annotation text.
227  * Added gaussianBlurImage() method.
228  * Fixed bug in floodFillTexture().
229  * Re-worked error reporting methodology to use re-entrant error
230    reporting rather than the previous method (based on call-backs)
231    which required thread specific data.
232  * Should be thread-safe under Win32 now.
233
234(0.9.2)

238    writePixels, in order to provide low-level access to Image pixels.
239  * Bugfix: size method was setting Options size, but not Image rows
240    and columns.
241
242(0.9.1)
243  * Released with ImageMagick 5.1.0
244  * Added additional constructors, read, and write methods for BLOBs
245    to make BLOBs easier to use.
246  * Added the medianFilter() method to Image.
247  * Renamed transformColorSpace() to colorSpace() and added a
248    colorSpace() accessor method.
249  * Renamed psPageSize() to page(), which now properly returns the
250    actual attribute from the image, rather than the image options.
251    This is important in order to manipulate GIF animations.
252  * Bug fixes.
253
254(0.9)
255  * Ported to ImageMagick 5.0.
256  * BLOB sizes are now specified using size_t type.
257  * Rotate() no longer accepts sharpen or crop options.
258  * Shear() No longer accepts a crop option.
259  * FontPointsize() now takes a double.
260  * The condense, uncondense, and condensed methods have been removed
261    since ImageMagick 5.0 no longer uses run-length encoding.
262  * The quantizeError method has been removed since it never worked.
263  * The cacheThreshold method is added to set the threshold of
264    ImageMagick's image cache.
265
266(0.8.9)
267  * Released with ImageMagick 4.2.9
268  * Blob reference counting was totally broken, leading to a memory
269    leak if it was used.  Fixed by starting reference count from one
270    rather than zero.
271
272(0.8.8)
273  * Fixed a Image constructor bug when constructing from a Blob
274
275(0.8.7)
276  * Bugfix: condensed() was returning wrong state.
277
278(0.8.6)
279  * Color is now based on ImageMagick's RunlengthPacket structure (via a
280    pointer) so that it may eventually be used to represent an image
281    pixel.  This is currently a work in progress.
282
283(0.8.5)
284  * Headers are now installed under prefix/include/Magick++ on Unix
285    systems with the exception that Magick++.h is installed under
286    prefix/include as it was before.  Programs which include Magick++.h
287    (the documented approach) should not be impacted.
288  * Image constructors to construct an image from a BLOB.
289  * Image read and write methods to decode and encode images stored in a
290    BLOB.  This allows reading/writing image "files" from/to memory rather
291    than a traditional file.
292
293(0.8.4)
294  * New mapImages algorithm maps a sequence of images to the colormap of
295    a provided image.
296  * New quantizeImages algorithm computes and applies a common colormap
297    to a sequence of images.
298
299(0.8.3)

301  * Blob supports default constructor.
302  * New Blob method updateNoCopy() to support efficient initialization by
303    derived class.
304
305(0.8.2)
306  * Uses libtool 1.3 to build library under Unix and Cygwin (static lib only).
307  * Added Blob class to support supplying formatted binary data to methods.
308  * Added support for setting ICC and IPTC profiles from a binary BLOB.
309  * Added support for transformations of image data to/from alternate
310    colorspace (e.g. CYMK).
311  * Added support for 'pinging' an image (get image dimensions/size quickly).
312  * Added 'uncondense' method to de-compress in-memory image data.
313  * Added support for annotation using rotated text.
314
315(0.8.1)
316  * Added support for setting alpha in Magick::Color
317  * Set/get color alpha in Magick::Image::pixelColor() for DirectClass images.

321  * Improved Microsoft Visual C++ build environment.
322
323(0.7.4)
324  * Added animateImages() and displayImages() to MagickSTL.h.
325  * Added function objects to support setting image attributes.
326
327(0.7.3)
328  * Image::penTexture() now takes Image reference rather than
329    Image pointer.  Set Image to invalid using isValid(false)
330    to unset texture.
331  * Attribute methods that take Color, Geometry, Image, or string
332    arguments may now unset the attribute by setting the state of
333    the object to invalid using isValid(false), or the empty string
334    (in the case of string).  This allows full control over ImageMagick
335    attributes which are stored as C strings which may be set to NULL.
336  * Updated for ImageMagick 4.2.1
337
338(0.7.2)
339  * Added STL function object support for all Image manipulation
340    methods to support operating on all or part of the images
341    stored in an STL container.
342
343(0.7.1)
344  * Added Coordinate class and methods in Drawable to support x,y
345    coordinates.
346  * Changed coordinate parameters from unsigned int to double in Drawable.
347  * Changed polygon methods in Drawable to use STL list argument.
348  * Added STL list based draw method to Image.
349  * Changed Exception heirarchy to support Warning and Error sub-classes.
350    Most exception class names have changed.
351
352(0.7)
353  * Updated for ImageMagick 4.2.0
354  * Added support for flood-filling and drawing with texture.
355  * Montage supported.
356  * Oodles of bugs fixed.
357  * Implemented image attribute tests.
358  * Implemented PerlMagick 'demo' and 'shapes' demo programs in Magick++.

361(0.6)
362  * Initial support for integrating image-list oriented operations with
363    STL containers.
364

367  * Compiles and runs under Windows using Visual C++ 5.X or later.
368  * Users of Magick++ API are not exposed to ImageMagick headers.
369  * Magick++ API is namespaced under "Magick".
370  * "Magick" prefix removed from object names.
371  * User options are now completely contained within Image object.
372    There is no longer a MagickOptions parameter to some methods.
373
374(0.1)
375  * All ImageMagick operations which operate on individual images are
376    supported.
377  * Image objects have value semantics, avoid unnecessary image
378    copies through the use of reference counting, and may be compared
379    via standard operators.
380  * Geometry, color, annotations, and user-options are supported by
381    separate classes.
382  * Errors are reported synchronously via C++ exceptions.
