patch
The patch for zoomLineWidth(float) method
Delivered the fix in R3_6_maintenance and HEAD. Trivial fix - suggested and tested by Simon. |
Build Identifier: 20100917-0705 The ScaledGraphics class does not scale line widths, leading to bizarre output when the figure is rendered as high-resolution bitmaps (hint, the lines disappear from the printed page!) The method currently reads: float zoomLineWidth(float w) { return w; } It should read: float zoomLineWidth(float w) { return (float) zoom * w; } Reproducible: Always
