Stroking color is same for every line.
Graphics.color/bg color comparison didnt work.
I tried something like discardLines4Rectangele(p0, p1, p2, p3) at the start of
appendrectangle.
Maybe some rectangle overrides it, but no luck.
I am not using linepath directly, this is what it looks like.
@Override
public void appendRectangle(Point2D p0, Point2D p1, Point2D p2, Point2D
p3) {
//discardLines4Rectangele(p0, p1, p2, p3);
this.lineList.add(new LineInfo(new Point2D.Double(p0.getX(),
p0.getY()),new Point2D.Double(p1.getX(), p1.getY()),
this.getGraphicsState().getLineWidth()));
this.lineList.add(new LineInfo(new Point2D.Double(p1.getX(),
p1.getY()),new Point2D.Double(p2.getX(), p2.getY()),
this.getGraphicsState().getLineWidth()));
this.lineList.add(new LineInfo(new Point2D.Double(p2.getX(),
p2.getY()),new Point2D.Double(p3.getX(), p3.getY()),
this.getGraphicsState().getLineWidth()));
this.lineList.add(new LineInfo(new Point2D.Double(p3.getX(),
p3.getY()),new Point2D.Double(p0.getX(), p0.getY()),
this.getGraphicsState().getLineWidth()));
super.appendRectangle(p0, p1, p2, p3);
}
@Override
public void lineTo(float x, float y) {
Point2D currentPoint = this.getCurrentPoint();
//Graphics2D graphics = this.getGraphics();
//PDGraphicsState state = this.getGraphicsState();
this.lineList.add(new LineInfo(new
Point2D.Double(currentPoint.getX(), currentPoint.getY()), new
Point2D.Double((double)x, (double)y), this.getGraphicsState().getLineWidth()));
super.lineTo(x, y);
}
Any other idea?
Is it possible to debug where those lines are "ignored" while rendering?
They are buffered right? The actual rendering is happening all of this stuff
done?
Not: cant find any working upload server atm (annoying company policy)

Attachments usually don't go through, you'd have to upload them somewhere.
In PageDrawer.java, the lines are in "linePath". For stroke it's the stroking
color.
