ulrich gratz updated PDFBOX-4159:
---------------------------------
Description:
When i use a large amount of {{AffineTransformations}} (apprx. more than 35)
the resulting document will open in Acrobat Reader, but each time a warning is
displayed, that there is a defect in the document. The code I use is like:
{code:java}
for (int i = 0; i < 50; i++) {
context.process(new ParagraphSegment("XXXXXXXXXXXXXXXXXX")); // basically
render line of text
final float y = VIEWPORT_TOP - this.heightOfRenderedSegments -
this.currentFont.getHeight();
Matrix translationMatrix = new
Matrix(AffineTransform.getTranslateInstance(VIEWPORT_LEFT, y));
this.contentStream.transform(translationMatrix)
}
{code}
When i skip the transformations or reduce the amount to 30, everything is fine.
The size of {{ty}} or page breaks do _not_ have an influence on the result, it
seems to be the amount of transforms.
I attached a simple PDF sporting the described effect. *Please note:* The
effect only occurs in the standalone Acrobat Reader, not the acrobat browser
plugin. So to see the error, download the PDF from this ticket and open it
independent from the browser.
