Re: Lines are hiding in AWTViewer perhaps Bug in Java2DRenderer or Java2D itsself
So here the workaround that did it to me:
protected void drawBorders(Rectangle2D.Float borderRect, BorderProps
bpsBefore, BorderProps bpsAfter, BorderProps bpsStart, BorderProps bpsEnd)
{
float x1 = borderRect.x;
float y1 = borderRect.y;
float x2 = borderRect.x + borderRect.width;
float y2 = borderRect.y + borderRect.height;
if (bpsStart != null)
{
saveGraphicsState();
state.updateColor(bpsStart.color);
state.updateStroke(bpsStart.width / 1000f,
bpsStart.style);
state.getGraph().draw(new Line2D.Float(x1, y1, x1, y2));
restoreGraphicsState();
}
if (bpsBefore != null)
{
saveGraphicsState();
state.updateColor(bpsBefore.color);
state.updateStroke(bpsBefore.width / 1000f,
bpsBefore.style);
state.getGraph().draw(new Line2D.Float(x1, y1, x2, y1));
restoreGraphicsState();
}
if (bpsEnd != null)
{
saveGraphicsState();
state.updateColor(bpsEnd.color);
state.updateStroke(bpsEnd.width / 1000f, bpsEnd.style);
state.getGraph().draw(new Line2D.Float(x2, y1, x2, y2));
restoreGraphicsState();
}
if (bpsAfter != null)
{
saveGraphicsState();
state.updateColor(bpsAfter.color);
state.updateStroke(bpsAfter.width / 1000f,
bpsAfter.style);
state.getGraph().draw(new Line2D.Float(x1, y2, x2, y2));
restoreGraphicsState();
}
}
Dont know why a lot of calculating is done in the original drawBorderLine()
cause the workaround above is doin it pretty well and all borders are shown
thats the most important thing to me.

Re: Lines are hiding in AWTViewer perhaps Bug in Java2DRenderer or Java2D itsself
Me again,
I solved the problem not the whole but a piece of it.
I have overwritten drawBorders() in AWTRenderer with this...
protected void drawBorders(Rectangle2D.Float borderRect, BorderProps
bpsBefore, BorderProps bpsAfter, BorderProps bpsStart, BorderProps bpsEnd)
{
float x1 = borderRect.x;
float y1 = borderRect.y;
float x2 = borderRect.x + borderRect.width;
float y2 = borderRect.y + borderRect.height;
if (bpsStart != null)
{
saveGraphicsState();
state.updateColor(Color.BLACK);
state.updateStroke(0.1f, EN_SOLID);
state.getGraph().draw(new Line2D.Float(x1, y1, x1, y2));
restoreGraphicsState();
}
if (bpsBefore != null)
{
saveGraphicsState();
state.updateColor(Color.BLACK);
state.updateStroke(0.1f, EN_SOLID);
state.getGraph().draw(new Line2D.Float(x1, y1, x2, y1));
restoreGraphicsState();
}
if (bpsEnd != null)
{
saveGraphicsState();
state.updateColor(Color.BLACK);
state.updateStroke(0.1f, EN_SOLID);
state.getGraph().draw(new Line2D.Float(x2, y1, x2, y2));
restoreGraphicsState();
}
if (bpsAfter != null)
{
saveGraphicsState();
state.updateColor(Color.BLACK);
state.updateStroke(0.1f, EN_SOLID);
state.getGraph().draw(new Line2D.Float(x1, y2, x2, y2));
restoreGraphicsState();
}
}
Fast and stupid solution but it worked for me =)
And what can I say all borders are painted correct, so i think perhaps in
drawBackAndBorders() or drawBorders()
somewhere there there must be a problem.
I dont think anymore its a prob with bufferedimages.
Dont know where to go on...

Re: Lines are hiding in AWTViewer perhaps Bug in Java2DRenderer or Java2D itsself
Oh, I think you hit the nail on the head with that link. It is indeed so that the page is first painted to a bitmap which is then painted on the panel. So, it appears as if painting the page directly on the panel could potentially solve the problem. But what I don't know is whether there was a particular reason that we use (and cache) bitmaps to paint the pages instead of painting them directly. At first glance, it appears to be a waste of a lot of memory. If I were you I'd experiment with changing ImageProxyPanel.paintComponent().

Re: Lines are hiding in AWTViewer perhaps Bug in Java2DRenderer or Java2D itsself
Nice nice. I'll take a look at ImageProxyPanel. Thank you for the tip. I'll do a reply if I have found a solution but that can take a time cause im not that deep enough to the source-code =) but i give it a try.

-UPDATE- I realized that the debug view in the AWT-viewer can handle the scaleing thing right. All debuging lines are shown in every zoomsteps correct. Perhaps i see a possible solution in this. I'm still searching and trying... Jeremias Maerki-2 wrote: Oh, I think you hit the nail on the head with that link.

Lines are hiding in AWTViewer perhaps Bug in Java2DRenderer or Java2D itsself
Hi folks, I use the zooming functionality in the AWTViewer a lot! I realized a notgoodie =) in the AWTViewer with certain PDF-Files with a lot of lines, less a pixel high. Not all lines and borders are visible under certain zoom-steps in the panel. You see it also in the sample borders.fo when you zoom in and out that some lines are hiding. I think it was page 4. So not all lines are shown in the panel but the print is all fine! How can i ensure that lines are visible when the clip is less than pixel high while zooming in and out. Its probably a bug in the java2d api i think or the java2drenderer ? Definitly its a clipping issue where Java will not display a line if the clip width is smaller 0.99 i think. Has anyone tips where i can find the line to fix the bug myself. -- View this message in context: http://www.nabble.com/Lines-are-hiding-in-AWTViewer-perhaps-Bug-in-Java2DRenderer-or-Java2D-itsself-tf3049992.html#a8478339 Sent from the FOP - Users mailing list archive at Nabble.com. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
