Revision history for Perl extension Imager::Graph.

Imager-Graph 0.09 - 05 Aug 2010

Bug fixes:

refresh the t10_lin_fount test image
avoid use_automatic_axis() for the second area test, since systems without Chart::Math::Axis will produce a different image.

Imager-Graph 0.08 - 03 Aug 2010

Now depends on Imager 0.75.

More cool changes from Patrick Michaud:

Other changes:

horizonal_gridlines (vertical charts) and vertical_gridlines (horizontal charts) are now features and can be enabled like other features (or disabled)
hoisted the dashed-line drawing into Imager::Graph::_line() and added a getline() method to retrieve line style information.
features enabled earlier in the style list can now be disabled with a feature "no{stylename}" when features are supplied as an arrayref or scalar. eg. "nograph_outline". If you supply features as a hashref you can disable a feature with: { stylename => 0 }
for vertical and horizontal charts, allow the outline of the graph area (graph_outline) to be disabled (with nograph_outline in features.) or styled (graph.outline)
for vertical and horizontal charts, allow the fill of the graph area to be controlled separately from the base bg (graph.fill)
tests

Bug fixes:

generate y-axis tic-label widths baed on the labels actually used.
make draw() idempotent for vertical charts
multiple calls to draw() no longer return the same image object
labels supplied to draw() are now used for vertical and horizontal charts
Imager::Graph::Horizontal::add_column_data_series() renamed to add_bar_data_series() and now adds the series as a "bar" series. add_column_data_series() did nothing useful for a horizontal chart.

Lots of cool changes from Patrick Michaud:

added Bar, Column. StackedColumn and Line charts. https://rt.cpan.org/Ticket/Display.html?id=5 [*]
new ocean style
new ocean_flat style
methods to set chart style attributes, in addition to the style parameters passed to draw().

Bug fixes:

missing a font parameter when we have a chart with text no longer results in an exception, but in a false returned and a message in error() as with other errors. https://rt.cpan.org/Ticket/Display.html?id=2872
the mono style now disables anti-aliasing by default

[*] this was the oldest open bug on rt.cpan.org, now #7 is, still an Imager-Graph issue

Removed ancient Imager cruft from the documentation
round the dimensions used within the legend to integers to prevent later truncation from causing uneven output.
add horizontal legend boxes
add a new style "primary" which is primary_red with a light grey background, and made that the default, so the default graphs aren't quite so ugly.
zero-sized segments were drawn as covering the whole pie. Skip drawing zero sized segments. https://rt.cpan.org/Ticket/Display.html?id=34813
round the pie radius down to avoid running over the edge of the image
changed the pie maxsegments default to 0.01 from 0.05
removed the obsolete pie blur style information
documented some of the pie chart specific style settings
changed the default drop shadow style to a translucent fill so the background can show through.

This release is an attempt to work around the inconsistent text output issues.

created Imager::Font::Test which simply outputs boxes instead of text to produce consistent graph images for comparison.

This is a clean up release, removing code required for ancient releases of Imager, and otherwise modernizing the code.

skip all tests if we can't load the font
Save test results to ppm, so we can generate images even if we don't have PNG support in Imager.
instead of the old draw-no-aa-then-blur-the-result hack, we now use arc()'s aa option
tests now use Test::More
remove the old circle fudge hack, since Imager fixed arc fills a while ago
strictify Makefile.PL, include the LICENSE, use the correct version check for including the extra WriteMakefile keys
various changes for Kwalitee
remove fancy_fills check, we now depend on an Imager release that supports fountain fills.
