In pixmap: Bitmap Images / Pixel Maps

pixmap 0.4-13

• Achim Zeileis takes over maintenance from Friedrich Leisch.

pixmap 0.4-12

• Fixed some NAMESPACE problems.

pixmap 0.4-11

• Added dummy NAMESPACE file.

• Move class definitions to separate file, no Collate in DESCRIPTION.

pixmap 0.4-10

• Explicitly mention in the help file that read.pnm only works for files, not other conntection.

• Fixed a bug in write.pnm that tried to open the same connection twice.

pixmap 0.4-9

• Fixed a minor glitch in write.pnm.

pixmap 0.4-8

• Fixed a bug that prevented plotting images with only 1 row (bug report by Robert Esswein).

pixmap 0.4-7

• Use LazyLoad instead of SaveImage.

pixmap 0.4-6

• Modified one of the regression tests for changes in R 2.4: terrain.colors() now return transparency information -> do not use it in example.

pixmap 0.4-5

• Standardized license field in DESCRIPTION file.

pixmap 0.4-4

• Fixed a bug in the prototype of class "pixmap".

pixmap 0.4-3

• New example for overlaying plots in help(pixmap) submitted by Stephan Matthiesen.

pixmap 0.4-2

• Adjust for R 2.0.0.

• Fixed a bug in coercion from pixmapIndexed to pixmapRGB.

• 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.

pixmap 0.4-1

• Fixed a bug in write.pnm() that wrote grey images in PPM format.

• The channel information was not changed when converting between RGB and grey pixmaps.

• The maxval in PNM headers must be less than 65536, not less than 256.

pixmap 0.4-0

• read.pnm(): Vectorized (and renamed) as.integer.bytes() which provides a huge performance gain for reading "PBM" (b/w bitmaps).

• New function addlogo().

pixmap 0.3-4

• Clarified documentation of read.pnm (file name extensions are ignored).

pixmap 0.3-3

• Fixed some codoc problems (missing aliases).

pixmap 0.3-1

• read.pnm(): Changes made to function reading and parsing PNM file headers to permit comments of arbitrary length.

pixmap 0.3-0

• 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.

• Added support for subsetting, see example(pixmap).

• New: addChannels() and getChannels().

pixmap 0.2-1

• 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()

pixmap 0.1-2

• Fixed bugs in plotting, read.pnm and write.pnm which confused dimensions (rows versus columns), but together let plots look OK.
