13Other changes:
14
86f73dc2
TC
15 - horizonal_gridlines (vertical charts) and vertical_gridlines
16 (horizontal charts) are now features and can be enabled like other
56b495c0
TC
17 features (or disabled)
18
19 - hoisted the dashed-line drawing into Imager::Graph::_line() and
20 added a _get_line() method to retrieve line style information.
21
22 - features enabled earlier in the style list can now be disabled with
23 a feature "no{stylename}" when features are supplied as an arrayref
24 or scalar. eg. "nograph_outline". If you supply features as a hashref
25 you can disable a feature with:
26 { stylename => 0 }
27

TC
28 - for vertical and horizontal charts, allow the outline of the graph
29 area (graph_outline) to be disabled (with nograph_outline in
30 features.) or styled (graph.outline)
56b495c0 31
86f73dc2
TC
32 - for vertical and horizontal charts, allow the fill of the graph
33 area to be controlled separately from the base bg (graph.fill)

56b495c0
TC
36 - tests
37
38Bug fixes:

40 - generate y-axis tic-label widths baed on the labels actually used.

47 charts

5057a68f
TC
49 - Imager::Graph::Horizontal::add_column_data_series() renamed to
50 add_bar_data_series() and now adds the series as a "bar" series.
51 add_column_data_series() did nothing useful for a horizontal chart.
52

101

102 - round the dimensions used within the legend to integers to prevent
103 later truncation from causing uneven output.
104
33a928b7
TC
105 - add horizontal legend boxes
106
7b94e723
TC
107 - add a new style "primary" which is primary_red with a light grey
108 background, and made that the default, so the default graphs aren't
109 quite so ugly.
110
26c93f46
TC
111 - zero-sized segments were drawn as covering the whole pie. Skip
112 drawing zero sized segments.

128=================
129
130This release is an attempt to work around the inconsistent text output
131issues.
132
133 - created Imager::Font::Test which simply outputs boxes instead of
134 text to produce consistent graph images for comparison.

140This is a clean up release, removing code required for ancient
141releases of Imager, and otherwise modernizing the code.
142
bfcf9414
TC
143 - skip all tests if we can't load the font
144
145 - Save test results to ppm, so we can generate images even if we don't
146 have PNG support in Imager.
147
148 - instead of the old draw-no-aa-then-blur-the-result hack, we now use
149 arc()'s aa option
150
151 - tests now use Test::More
152
153 - remove the old circle fudge hack, since Imager fixed arc fills a
154 while ago
155
156 - strictify Makefile.PL, include the LICENSE, use the correct version
157 check for including the extra WriteMakefile keys
