This shows up as the bounding box becomes a few pixels to wide when spaces or characters that extend below the baseline is used. If justa few simple characters i.e. "abc" is used then it is corect but if you take the string (for example) " ab cgAj" then the bounding box is lightly to wide. All texts at zero angle. I have made a simple example at http://jpgraph.fan-atics.com/viewtopic.php?t=795 which clearly illustrates and describes the problem. In that thread there is also a suggestion for a fix (which I hadn't had time to verify myself). It seems that the kerning distance is not properly added to the running position. Hence, the fix should be to in gdft.c replace pen.x += delta.x; with pen.x += delta.x; penf.x += delta.x; ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=22613&edit=1
