1 Revision history for Perl extension Imager::Graph.
3 - POD fixes based on a report from Stefan Limbache
5 - skip POD tests unless AUTOMATED_TESTING or IMAGER_AUTHOR_TESTING is
8 Imager-Graph 0.10 - 7 May 2012
11 - loosen up image comparisons - the rounding change in Imager 0.90
12 made small changes to many pixels in fountain fills
13 https://rt.cpan.org/Ticket/Display.html?id=76955
14 It should fix the following too.
15 https://rt.cpan.org/Ticket/Display.html?id=68031
17 - negative_bg (or set via set_negative_background()) can now be a
19 https://rt.cpan.org/Ticket/Display.html?id=59532
21 - calculation of the zero position for horizontal charts was broken,
22 this resulted charts with negative data values having the
23 negative_bg color filled from the left side of the chart off the
24 right side of the image.
26 - Imager::Graph now requires at least perl 5.6.
28 - hoisted the common cmpimg() function into a separate test module
30 - convert shipped comparison images from ppm to png to reduce size
32 Imager-Graph 0.09 - 05 Aug 2010
37 - refresh the t10_lin_fount test image
39 - avoid use_automatic_axis() for the second area test, since systems
40 without Chart::Math::Axis will produce a different image.
42 Imager-Graph 0.08 - 03 Aug 2010
45 Now depends on Imager 0.75.
47 More cool changes from Patrick Michaud:
50 https://rt.cpan.org/Ticket/Display.html?id=7
54 - horizonal_gridlines (vertical charts) and vertical_gridlines
55 (horizontal charts) are now features and can be enabled like other
56 features (or disabled)
58 - hoisted the dashed-line drawing into Imager::Graph::_line() and
59 added a _get_line() method to retrieve line style information.
61 - features enabled earlier in the style list can now be disabled with
62 a feature "no{stylename}" when features are supplied as an arrayref
63 or scalar. eg. "nograph_outline". If you supply features as a hashref
64 you can disable a feature with:
67 - for vertical and horizontal charts, allow the outline of the graph
68 area (graph_outline) to be disabled (with nograph_outline in
69 features.) or styled (graph.outline)
71 - for vertical and horizontal charts, allow the fill of the graph
72 area to be controlled separately from the base bg (graph.fill)
78 - generate y-axis tic-label widths baed on the labels actually used.
80 - make draw() idempotent for vertical charts
82 - multiple calls to draw() no longer return the same image object
84 - labels supplied to draw() are now used for vertical and horizontal
87 - Imager::Graph::Horizontal::add_column_data_series() renamed to
88 add_bar_data_series() and now adds the series as a "bar" series.
89 add_column_data_series() did nothing useful for a horizontal chart.
92 Imager-Graph 0.07 - 21 May 2009
95 Lots of cool changes from Patrick Michaud:
97 - added Bar, Column. StackedColumn and Line charts.
98 https://rt.cpan.org/Ticket/Display.html?id=5 [*]
102 - new ocean_flat style
104 - methods to set chart style attributes, in addition to the style
105 parameters passed to draw().
109 - missing a font parameter when we have a chart with text no longer
110 results in an exception, but in a false returned and a message in
111 error() as with other errors.
112 https://rt.cpan.org/Ticket/Display.html?id=2872
114 - the mono style now disables anti-aliasing by default
116 [*] this was the oldest open bug on rt.cpan.org, now #7 is, still an
119 Imager-Graph 0.06 - 21 April 2008
122 - Removed ancient Imager cruft from the documentation
124 - round the dimensions used within the legend to integers to prevent
125 later truncation from causing uneven output.
127 - add horizontal legend boxes
129 - add a new style "primary" which is primary_red with a light grey
130 background, and made that the default, so the default graphs aren't
133 - zero-sized segments were drawn as covering the whole pie. Skip
134 drawing zero sized segments.
135 https://rt.cpan.org/Ticket/Display.html?id=34813
137 - round the pie radius down to avoid running over the edge of the
140 - changed the pie maxsegments default to 0.01 from 0.05
142 - removed the obsolete pie blur style information
144 - documented some of the pie chart specific style settings
146 - changed the default drop shadow style to a translucent fill so the
147 background can show through.
149 Imager-Graph 0.05 - 17 December 2007
152 This release is an attempt to work around the inconsistent text output
155 - created Imager::Font::Test which simply outputs boxes instead of
156 text to produce consistent graph images for comparison.
159 Imager-Graph 0.04 - 11 December 2007
162 This is a clean up release, removing code required for ancient
163 releases of Imager, and otherwise modernizing the code.
165 - skip all tests if we can't load the font
167 - Save test results to ppm, so we can generate images even if we don't
168 have PNG support in Imager.
170 - instead of the old draw-no-aa-then-blur-the-result hack, we now use
173 - tests now use Test::More
175 - remove the old circle fudge hack, since Imager fixed arc fills a
178 - strictify Makefile.PL, include the LICENSE, use the correct version
179 check for including the extra WriteMakefile keys
181 - various changes for Kwalitee
183 - remove fancy_fills check, we now depend on an Imager release that
184 supports fountain fills.
186 Imager-Graph 0.02 Sat Oct 6 20:36:31 2001
189 - replace ImUgly.ttf with a new version where % renders on my older PC
190 - remove some old test code that printed the Imager version
191 - moved into local CVS to simplify cross-platform tests
193 Imager-Graph 0.01 Tue Sep 12 23:03:25 2001
196 - original version; created by h2xs 1.19
197 - can draw some nice pie graphs
