1 Revision history for Perl extension Imager::Graph.
3 Imager-Graph 0.10 - 7 May 2012
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 now requires at least perl 5.6.
23 - hoisted the common cmpimg() function into a separate test module
25 - convert shipped comparison images from ppm to png to reduce size
27 Imager-Graph 0.09 - 05 Aug 2010
32 - refresh the t10_lin_fount test image
34 - avoid use_automatic_axis() for the second area test, since systems
35 without Chart::Math::Axis will produce a different image.
37 Imager-Graph 0.08 - 03 Aug 2010
40 Now depends on Imager 0.75.
42 More cool changes from Patrick Michaud:
45 https://rt.cpan.org/Ticket/Display.html?id=7
49 - horizonal_gridlines (vertical charts) and vertical_gridlines
50 (horizontal charts) are now features and can be enabled like other
51 features (or disabled)
53 - hoisted the dashed-line drawing into Imager::Graph::_line() and
54 added a _get_line() method to retrieve line style information.
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:
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)
66 - for vertical and horizontal charts, allow the fill of the graph
67 area to be controlled separately from the base bg (graph.fill)
73 - generate y-axis tic-label widths baed on the labels actually used.
75 - make draw() idempotent for vertical charts
77 - multiple calls to draw() no longer return the same image object
79 - labels supplied to draw() are now used for vertical and horizontal
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.
87 Imager-Graph 0.07 - 21 May 2009
90 Lots of cool changes from Patrick Michaud:
92 - added Bar, Column. StackedColumn and Line charts.
93 https://rt.cpan.org/Ticket/Display.html?id=5 [*]
97 - new ocean_flat style
99 - methods to set chart style attributes, in addition to the style
100 parameters passed to draw().
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
109 - the mono style now disables anti-aliasing by default
111 [*] this was the oldest open bug on rt.cpan.org, now #7 is, still an
114 Imager-Graph 0.06 - 21 April 2008
117 - Removed ancient Imager cruft from the documentation
119 - round the dimensions used within the legend to integers to prevent
120 later truncation from causing uneven output.
122 - add horizontal legend boxes
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
128 - zero-sized segments were drawn as covering the whole pie. Skip
129 drawing zero sized segments.
130 https://rt.cpan.org/Ticket/Display.html?id=34813
132 - round the pie radius down to avoid running over the edge of the
135 - changed the pie maxsegments default to 0.01 from 0.05
137 - removed the obsolete pie blur style information
139 - documented some of the pie chart specific style settings
141 - changed the default drop shadow style to a translucent fill so the
142 background can show through.
144 Imager-Graph 0.05 - 17 December 2007
147 This release is an attempt to work around the inconsistent text output
150 - created Imager::Font::Test which simply outputs boxes instead of
151 text to produce consistent graph images for comparison.
154 Imager-Graph 0.04 - 11 December 2007
157 This is a clean up release, removing code required for ancient
158 releases of Imager, and otherwise modernizing the code.
160 - skip all tests if we can't load the font
162 - Save test results to ppm, so we can generate images even if we don't
163 have PNG support in Imager.
165 - instead of the old draw-no-aa-then-blur-the-result hack, we now use
168 - tests now use Test::More
170 - remove the old circle fudge hack, since Imager fixed arc fills a
173 - strictify Makefile.PL, include the LICENSE, use the correct version
174 check for including the extra WriteMakefile keys
176 - various changes for Kwalitee
178 - remove fancy_fills check, we now depend on an Imager release that
179 supports fountain fills.
181 Imager-Graph 0.02 Sat Oct 6 20:36:31 2001
184 - replace ImUgly.ttf with a new version where % renders on my older PC
185 - remove some old test code that printed the Imager version
186 - moved into local CVS to simplify cross-platform tests
188 Imager-Graph 0.01 Tue Sep 12 23:03:25 2001
191 - original version; created by h2xs 1.19
192 - can draw some nice pie graphs
