12 - negative_bg (or set via set_negative_background()) can now be a
13 fill.
14 https://rt.cpan.org/Ticket/Display.html?id=59532
15
16 - calculation of the zero position for horizontal charts was broken,
17 this resulted charts with negative data values having the
18 negative_bg color filled from the left side of the chart off the
19 right side of the image.

27Imager-Graph 0.09 - 05 Aug 2010
28=================
29
30Bug fixes:
31
32 - refresh the t10_lin_fount test image
33
34 - avoid use_automatic_axis() for the second area test, since systems
35 without Chart::Math::Axis will produce a different image.

47Other changes:
48
86f73dc2
TC
49 - horizonal_gridlines (vertical charts) and vertical_gridlines
50 (horizontal charts) are now features and can be enabled like other
56b495c0
TC
51 features (or disabled)
52
53 - hoisted the dashed-line drawing into Imager::Graph::_line() and
54 added a _get_line() method to retrieve line style information.
55
56 - features enabled earlier in the style list can now be disabled with
57 a feature "no{stylename}" when features are supplied as an arrayref
58 or scalar. eg. "nograph_outline". If you supply features as a hashref
59 you can disable a feature with:
60 { stylename => 0 }
61
86f73dc2
TC
62 - for vertical and horizontal charts, allow the outline of the graph
63 area (graph_outline) to be disabled (with nograph_outline in
64 features.) or styled (graph.outline)
56b495c0 65
86f73dc2
TC
66 - for vertical and horizontal charts, allow the fill of the graph
67 area to be controlled separately from the base bg (graph.fill)
56b495c0
TC
68
69 - tests
70
71Bug fixes:
72
73 - generate y-axis tic-label widths baed on the labels actually used.
74
75 - make draw() idempotent for vertical charts
76
86f73dc2 77 - multiple calls to draw() no longer return the same image object
56b495c0
TC
78
79 - labels supplied to draw() are now used for vertical and horizontal
80 charts
81
5057a68f
TC
82 - Imager::Graph::Horizontal::add_column_data_series() renamed to
83 add_bar_data_series() and now adds the series as a "bar" series.
84 add_column_data_series() did nothing useful for a horizontal chart.

100 parameters passed to draw().
101
102Bug fixes:
103
104 - missing a font parameter when we have a chart with text no longer
105 results in an exception, but in a false returned and a message in
106 error() as with other errors.
107 https://rt.cpan.org/Ticket/Display.html?id=2872
108
109 - the mono style now disables anti-aliasing by default

115=================
116

118
379c5b02

119 - round the dimensions used within the legend to integers to prevent
120 later truncation from causing uneven output.
121
33a928b7
TC
122 - add horizontal legend boxes
123
7b94e723
TC
124 - add a new style "primary" which is primary_red with a light grey
125 background, and made that the default, so the default graphs aren't
126 quite so ugly.
127
26c93f46
TC
128 - zero-sized segments were drawn as covering the whole pie. Skip
129 drawing zero sized segments.

131

145=================
146
147This release is an attempt to work around the inconsistent text output
148issues.
149
150 - created Imager::Font::Test which simply outputs boxes instead of
151 text to produce consistent graph images for comparison.

157This is a clean up release, removing code required for ancient
158releases of Imager, and otherwise modernizing the code.
159
bfcf9414
TC
160 - skip all tests if we can't load the font
161
162 - Save test results to ppm, so we can generate images even if we don't
163 have PNG support in Imager.
164
165 - instead of the old draw-no-aa-then-blur-the-result hack, we now use
166 arc()'s aa option
167
168 - tests now use Test::More
169
170 - remove the old circle fudge hack, since Imager fixed arc fills a
171 while ago
172
173 - strictify Makefile.PL, include the LICENSE, use the correct version
174 check for including the extra WriteMakefile keys
175
