1 Revision history for Perl extension Imager::Graph.
3 Imager-Graph 0.10 - unreleased
6 - loosen up image comparisons - the rounding change in Imager 0.90
7 made small changes to many pixels in fountain fills
8 https://rt.cpan.org/Ticket/Display.html?id=76955
9 It should fix the following too.
10 https://rt.cpan.org/Ticket/Display.html?id=68031
12 - negative_bg (or set via set_negative_background()) can now be a
14 https://rt.cpan.org/Ticket/Display.html?id=59532
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.
21 Imager-Graph 0.09 - 05 Aug 2010
26 - refresh the t10_lin_fount test image
28 - avoid use_automatic_axis() for the second area test, since systems
29 without Chart::Math::Axis will produce a different image.
31 Imager-Graph 0.08 - 03 Aug 2010
34 Now depends on Imager 0.75.
36 More cool changes from Patrick Michaud:
39 https://rt.cpan.org/Ticket/Display.html?id=7
43 - horizonal_gridlines (vertical charts) and vertical_gridlines
44 (horizontal charts) are now features and can be enabled like other
45 features (or disabled)
47 - hoisted the dashed-line drawing into Imager::Graph::_line() and
48 added a _get_line() method to retrieve line style information.
50 - features enabled earlier in the style list can now be disabled with
51 a feature "no{stylename}" when features are supplied as an arrayref
52 or scalar. eg. "nograph_outline". If you supply features as a hashref
53 you can disable a feature with:
56 - for vertical and horizontal charts, allow the outline of the graph
57 area (graph_outline) to be disabled (with nograph_outline in
58 features.) or styled (graph.outline)
60 - for vertical and horizontal charts, allow the fill of the graph
61 area to be controlled separately from the base bg (graph.fill)
67 - generate y-axis tic-label widths baed on the labels actually used.
69 - make draw() idempotent for vertical charts
71 - multiple calls to draw() no longer return the same image object
73 - labels supplied to draw() are now used for vertical and horizontal
76 - Imager::Graph::Horizontal::add_column_data_series() renamed to
77 add_bar_data_series() and now adds the series as a "bar" series.
78 add_column_data_series() did nothing useful for a horizontal chart.
81 Imager-Graph 0.07 - 21 May 2009
84 Lots of cool changes from Patrick Michaud:
86 - added Bar, Column. StackedColumn and Line charts.
87 https://rt.cpan.org/Ticket/Display.html?id=5 [*]
91 - new ocean_flat style
93 - methods to set chart style attributes, in addition to the style
94 parameters passed to draw().
98 - missing a font parameter when we have a chart with text no longer
99 results in an exception, but in a false returned and a message in
100 error() as with other errors.
101 https://rt.cpan.org/Ticket/Display.html?id=2872
103 - the mono style now disables anti-aliasing by default
105 [*] this was the oldest open bug on rt.cpan.org, now #7 is, still an
108 Imager-Graph 0.06 - 21 April 2008
111 - Removed ancient Imager cruft from the documentation
113 - round the dimensions used within the legend to integers to prevent
114 later truncation from causing uneven output.
116 - add horizontal legend boxes
118 - add a new style "primary" which is primary_red with a light grey
119 background, and made that the default, so the default graphs aren't
122 - zero-sized segments were drawn as covering the whole pie. Skip
123 drawing zero sized segments.
124 https://rt.cpan.org/Ticket/Display.html?id=34813
126 - round the pie radius down to avoid running over the edge of the
129 - changed the pie maxsegments default to 0.01 from 0.05
131 - removed the obsolete pie blur style information
133 - documented some of the pie chart specific style settings
135 - changed the default drop shadow style to a translucent fill so the
136 background can show through.
138 Imager-Graph 0.05 - 17 December 2007
141 This release is an attempt to work around the inconsistent text output
144 - created Imager::Font::Test which simply outputs boxes instead of
145 text to produce consistent graph images for comparison.
148 Imager-Graph 0.04 - 11 December 2007
151 This is a clean up release, removing code required for ancient
152 releases of Imager, and otherwise modernizing the code.
154 - skip all tests if we can't load the font
156 - Save test results to ppm, so we can generate images even if we don't
157 have PNG support in Imager.
159 - instead of the old draw-no-aa-then-blur-the-result hack, we now use
162 - tests now use Test::More
164 - remove the old circle fudge hack, since Imager fixed arc fills a
167 - strictify Makefile.PL, include the LICENSE, use the correct version
168 check for including the extra WriteMakefile keys
170 - various changes for Kwalitee
172 - remove fancy_fills check, we now depend on an Imager release that
173 supports fountain fills.
175 Imager-Graph 0.02 Sat Oct 6 20:36:31 2001
178 - replace ImUgly.ttf with a new version where % renders on my older PC
179 - remove some old test code that printed the Imager version
180 - moved into local CVS to simplify cross-platform tests
182 Imager-Graph 0.01 Tue Sep 12 23:03:25 2001
185 - original version; created by h2xs 1.19
186 - can draw some nice pie graphs
