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.
