Comment #1 on issue 213 by [email protected]: artifacts in JComponent
border using PSwing
http://code.google.com/p/piccolo2d/issues/detail?id=213
Interesting, MatteBorder doesn't do this. In you code, replace LineBorder
with:
setBorder(BorderFactory.createMatteBorder(10,10,10,10,Color.blue));
LineBorder's implementation (the jdk source code that comes w/ MacOS) of
paintBorder() looks like this:
for(i = 0; i < thickness; i++) {
g.drawRect(x + i, y + i, width - i - i - 1, height - i - i - 1);
}
It just draws a consecutive of rectangles. I think when the Graphics object
is scaled this approach is leaving whitespace between the consecutive lines.
MatteBorder's implementation uses fillRects instead of consecutive of
single-pixel-width rectangles.
Not sure what Piccolo2D can do about this. I suppose we could detect the
use of LineBorder and recover from their implementation (ie., reimplement
the painting of LineBorders ourself to do something like what Matte does.)
