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.
