Changes in pixmap version 0.4-12 o Fixed some NAMESPACE problems Changes in pixmap version 0.4-11 o Added dummy NAMESPACE file o Move class definitions to separate file, no Collate in DESCRIPTION Changes in pixmap version 0.4-10 o Explicitly mention in the help file that read.pnm() only works for files, not other conntection. o Fixed a bug in write.pnm() that tried to open the same connection twice. Changes in pixmap version 0.4-9 o Fixed a minor glitch in write.pnm. Changes in pixmap version 0.4-8 o Fixed a bug that prevented plotting images with only 1 row (bug report by Robert Esswein). Changes in pixmap version 0.4-7 o Use LazyLoad instead of SaveImage. Changes in pixmap version 0.4-6 o Modified one of the regression tests for changes in R 2.4: terrain.colors() now return transparency information -> do not use it in example. Changes in pixmap version 0.4-5 o standardized license filed in DESCRIPTION file. Changes in pixmap version 0.4-4 o Fixed a bug in the prototype of class "pixmap". Changes in pixmap version 0.4-3 o New example for overlaying plots in help(pixmap) submitted by Stephan Matthiesen. Changes in pixmap version 0.4-2 o Adjust for R 2.0.0. o Fixed a bug in coercion from pixmapIndexed to pixmapRGB. o There was a bug in the methods package of R 1.9.x which was triggered by functions in pixmap, hence this version of the package depends on R >= 2.0.0. Changes in pixmap version 0.4-1 o Fixed a bug in write.pnm() that wrote grey images in PPM format. o The channel information was not changed when converting between RGB and grey pixmaps. o The maxval in PNM headers must be less than 65536, not less than 256. Changes in pixmap version 0.4-0 o read.pnm(): vectorized (and renamed) as.integer.bytes() which provides a huge performance gain for reading "PBM" (B & W bitmaps). o new function addlogo() Changes in pixmap version 0.3-4 o Clarified documentation of read.pnm (file name extensions are ignored). Changes in pixmap version 0.3-3 o fixed some codoc problems (missing aliases) Changes in pixmap version 0.3-1 o read.pnm(): changes made to function reading and parsing PNM file headers to permit comments of arbitrary length. Changes in pixmap version 0.3-0 o The whole package has moved to S4 classes and methods, hence all classes have a new representation. This also means that the code and the API are not fully backwards compatible with earlier versions of the package. o Added support for subsetting (see example(pixmap)). o New: addChannels() and getChannels(). Changes in pixmap version 0.2-1 o pixmap(): - Added arguments bbcent and cellres - nrow and ncol default to the respective dimensions of the data argument (if present). Hence, pixmap does the expected when given a matrix or an array. - data is rescaled to [0,1] for rgb and grey, and coerced to positive integers for indexed. - col can also be a function like rainbow() Changes in pixmap version 0.1-2 o Fixed bugs in plotting, read.pnm and write.pnm which confused dimensions (rows versus columns), but together let plots look OK.
