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

21Changes in pixmap version 0.4-9
22
23  o Fixed a minor glitch in write.pnm.
24

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).

32Changes in pixmap version 0.4-7
33
34  o Use LazyLoad instead of SaveImage.
35

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.

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.
