Comment #8 on issue 221 by v11...@gmail.com: Cannot draw veritical and horizontal lines of 0 width stroke using PPath http://code.google.com/p/piccolo2d/issues/detail?id=221 The attached java examples draws vertical and horizontal lines with BasicStroke(0). It works correctly. I think the problem is not in java itself. Attachments: ZeroWidthStroke.java 775 bytes -- Piccolo2D Developers Group: http://groups.google.com/group/piccolo2d-dev?hl=en

Comment #5 on issue 221 by atdi...@gmail.com: Cannot draw veritical and horizontal lines of 0 width stroke using PPath http://code.google.com/p/piccolo2d/issues/detail?id=221 If you need to render the strokes, you could try setting the stroke width to zero, which has the effect of always drawing a one-pixel wide stroke. This is true for the Win7/Java1.6.27 system I've tested it on, but afaik Piccolo doesn't have logic that ensures this, so it would be a side effect of what the JDK does. If the JDK doesn't document this as a contract, then it must be inadvertent or a bug and not to be relied on. We might want to remove that comment from the developer faq. -- Piccolo2D Developers Group: http://groups.google.com/group/piccolo2d-dev?hl=en

Comment #4 on issue 221 by heue...@gmail.com: Cannot draw veritical and horizontal lines of 0 width stroke using PPath http://code.google.com/p/piccolo2d/issues/detail?id=221 Is this a Piccolo2D bug or an AWT one? I don't see any mention of 1-pixel wide stroke width with BasicStroke(0) in the JDK javadocs. -- Piccolo2D Developers Group: http://groups.google.com/group/piccolo2d-dev?hl=en

Comment #3 on issue 221 by funny...@gmail.com: Cannot draw veritical and horizontal lines of 0 width stroke using PPath http://code.google.com/p/piccolo2d/issues/detail?id=221 I can confirm the bug with my system * Piccolo2d.java 1.3.1, * java version 1.6.0_22 OpenJDK Runtime Environment (IcedTea6 1.10.3) (fedora-59.1.10.3.fc15-i386) OpenJDK Server VM (build 20.0-b11, mixed mode) * Fedora 15 2.6.40.6-0.fc15.i686 If x1!=x2 or y1!=y2 then a one pixel width line is drawn in every zoom level, for stroke width zero. Attached is a test program to show the issue. Attachments: ZeroWidthStrokeBug.java 929 bytes -- Piccolo2D Developers Group: http://groups.google.com/group/piccolo2d-dev?hl=en

Comment #2 on issue 221 by v11...@gmail.com: Cannot draw veritical and horizontal lines of 0 width stroke using PPath http://code.google.com/p/piccolo2d/issues/detail?id=221 In the Developer's FAQ http://www.piccolo2d.org/learn/dev-faq.html section Why is my app so slow?, it states as follows: , If you need to render the strokes, you could try setting the stroke width to zero, which has the effect of always drawing a one-pixel wide stroke. And it brings very significant performance improvement using BasicStroke(0). The bug occurs when either x1 == x2, or y1 == y2 in the case of PPath.createLine(x1, y1, x2, y2); -- Piccolo2D Developers Group: http://groups.google.com/group/piccolo2d-dev?hl=en
