New 223 API supports multiple pixel views into the same image. Number of 224 available pixel views limited to the number of image rows + 1. 225 * Dramatically improved performance for text annotation and drawing. 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) 235 * Released with ImageMagick 5.1.1 236 * Should be thread-safe when used with POSIX threads (pthreads). 237 * Added methods getPixels, setPixels, syncPixels, readPixels, and 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) 300 * Ported to ImageMagick 4.2.6. 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. 318 319 (0.8) 320 * Transitioned to Beta 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++. 359 * Some parameters re-ordered due to experience from writing demo programs. 360 361 (0.6) 362 * Initial support for integrating image-list oriented operations with 363 STL containers. 364 365 (0.5) 366 * Compiles and runs under Unix using egcs release 1.1 or later. 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. 383 384
