1Changes in pixmap version 0.4-12 2 3 o Fixed some NAMESPACE problems 4 5 6Changes in pixmap version 0.4-11 7 8 o Added dummy NAMESPACE file 9 10 o Move class definitions to separate file, no Collate in DESCRIPTION 11 12 13Changes in pixmap version 0.4-10 14 15 o Explicitly mention in the help file that read.pnm() only works for 16 files, not other conntection. 17 18 o Fixed a bug in write.pnm() that tried to open the same connection twice. 19 20 21Changes in pixmap version 0.4-9 22 23 o Fixed a minor glitch in write.pnm. 24 25 26Changes in pixmap version 0.4-8 27 28 o Fixed a bug that prevented plotting images with only 1 row (bug 29 report by Robert Esswein). 30 31 32Changes in pixmap version 0.4-7 33 34 o Use LazyLoad instead of SaveImage. 35 36 37Changes in pixmap version 0.4-6 38 39 o Modified one of the regression tests for changes in R 2.4: 40 terrain.colors() now return transparency information 41 -> do not use it in example. 42 43 44Changes in pixmap version 0.4-5 45 46 o standardized license filed in DESCRIPTION file. 47 48 49Changes in pixmap version 0.4-4 50 51 o Fixed a bug in the prototype of class "pixmap". 52 53 54Changes in pixmap version 0.4-3 55 56 o New example for overlaying plots in help(pixmap) submitted by 57 Stephan Matthiesen. 58 59 60Changes in pixmap version 0.4-2 61 62 o Adjust for R 2.0.0. 63 64 o Fixed a bug in coercion from pixmapIndexed to pixmapRGB. 65 66 o There was a bug in the methods package of R 1.9.x which was 67 triggered by functions in pixmap, hence this version of the 68 package depends on R >= 2.0.0. 69 70 71Changes in pixmap version 0.4-1 72 73 o Fixed a bug in write.pnm() that wrote grey images in PPM format. 74 75 o The channel information was not changed when converting between 76 RGB and grey pixmaps. 77 78 o The maxval in PNM headers must be less than 65536, not less than 256. 79 80 81Changes in pixmap version 0.4-0 82 83 o read.pnm(): vectorized (and renamed) as.integer.bytes() which provides 84 a huge performance gain for reading "PBM" (B & W bitmaps). 85 86 o new function addlogo() 87 88 89Changes in pixmap version 0.3-4 90 91 o Clarified documentation of read.pnm (file name extensions are ignored). 92 93 94Changes in pixmap version 0.3-3 95 96 o fixed some codoc problems (missing aliases) 97 98 99Changes in pixmap version 0.3-1 100 101 o read.pnm(): changes made to function reading and parsing PNM file 102 headers to permit comments of arbitrary length. 103 104 105Changes in pixmap version 0.3-0 106 107 o The whole package has moved to S4 classes and methods, hence all 108 classes have a new representation. This also means that the code 109 and the API are not fully backwards compatible with earlier 110 versions of the package. 111 112 o Added support for subsetting (see example(pixmap)). 113 114 o New: addChannels() and getChannels(). 115 116 117Changes in pixmap version 0.2-1 118 119 o pixmap(): 120 - Added arguments bbcent and cellres 121 - nrow and ncol default to the respective dimensions of the data 122 argument (if present). Hence, pixmap does the expected when 123 given a matrix or an array. 124 - data is rescaled to [0,1] for rgb and grey, and coerced to positive 125 integers for indexed. 126 - col can also be a function like rainbow() 127 128 129Changes in pixmap version 0.1-2 130 131 o Fixed bugs in plotting, read.pnm and write.pnm which confused 132 dimensions (rows versus columns), but together let plots look OK. 133 134
