PDLineAppearanceHandler
Hi,
thanks for your support. We are using PDFBox 2.0.16 and it looks like
PDAnnotationLine.constructAppearances() makes the annotation rectangle a
lot larger when increasing the border width to values like 20, ... The
rectangle doesn't shrink again, when I decrease the border width again.
We are using this annotation as arrow.
It looks like PDLineAppearanceHandler.generateNormalAppearance
calculates too big/too small values in these lines:
rect.setLowerLeftX(Math.min(minX - Math.max(lineEndingSize * 10,
Math.abs(llo+ll+lle)), rect.getLowerLeftX()));
rect.setLowerLeftY(Math.min(minY - Math.max(lineEndingSize * 10,
Math.abs(llo+ll+lle)), rect.getLowerLeftY()));
rect.setUpperRightX(Math.max(maxX + Math.max(lineEndingSize * 10,
Math.abs(llo+ll+lle)), rect.getUpperRightX()));
rect.setUpperRightY(Math.max(maxY + Math.max(lineEndingSize * 10,
Math.abs(llo+ll+lle)), rect.getUpperRightY()));
Thanks a lot,
jens

Hi Tilman,
sorry, I wanted to say, that the value of the lowerLeftX value is
getting too small and the upperRightX values is getting too big. The
rectangle is never too small, just far too big.
Sorry for that.
Thanks again,
jens

Yes... I did that one, it was too difficult to calculate exactly the
size of that arrow part. I'm not surprised that it is too big, but that
it is too small??
I'd be interested to see an example of this.
