|Summary||0015246: JPGraph 3.5.x anti aliasing error in Ubuntu|
With the latest available version of JPGraph library (3.5.0b1) and the addition of the Theme system, the default 'Universal' theme forcefully calls $graph->img->SetAntiAliasing() in the SetupGraph method.
In Ubuntu (tested up to 12.10), this results in the graph not being drawn, due to an exception thrown (see attached screenshot for error 25128) because they do not use the php-bundled GD library , and the imageantialias() function does not exist.
It's worth noting that in the other available themes, this function call is commented out so the problem does not exist.
This is really a jpgraph issue which should be fixed upstream. However, it would appear that Asial Corporation (owner of JPGraph), is not actively maintaining the product - last release was in Oct 2010 and there are no communication channels to report issues.
