Zitat von [email protected]:
Hi,
Hi,
I have a quick question about the Y-axis of the PDPage object, and why
it starts at the bottom of the page, rather than the top? We have an
application coded using AquaPDF that plots the Y-axis coordinates from
top to bottom - however I've noticed PDFBox plots the Y-axis from bottom
to top. Is there any way to reverse this? Or somehow flip the page?
I've tried the "setRotation" method on the page object, but this had no
effect.
Any help is much appreciated,
The pdf specification is based on postscript which use this unusual
coordinate system. You can use the mediabox of the page to calculate
your y coordinate. Try pdPage.findMediaBox().getUpperRightY() - y to
get the right position. If it isn't the getUpperRightY() you can try
it with getLowerLeftY() didn't know exactly which one it is.
Thanks in advance,
David
Best regards
Thomas
