Comment #5 on issue 188 by atdi...@gmail.com: wrong line width when drawing
general shapes under SWT
http://code.google.com/p/piccolo2d/issues/detail?id=188
First thing to note is that this issue (pre-fix) only manifest itself for
on Windows (not Mac OSX or Ubuntu).
Second note is that adding 0.5 does not seem to be necessary. Just setting
the line width is sufficient:
public void drawPath(final Path p) {
gc.setLineWidth((int) lineWidth); // no need to + 0.5 here
gc.setTransform(swtTransform);
gc.drawPath(p);
gc.setTransform(null);
}
According to SWT's Javadoc for setLineWidth():
"Note that line width of zero is used as a hint to indicate that the
fastest possible line drawing algorithms should be used. This means that
the output may be different from line width one."
I believe we are getting this effective behavior by not setting lineWidth,
and the correct fix is to set the line width, without adding the 0.5.
Moving out of Fixed state.
