ulrich gratz updated PDFBOX-4159:
---------------------------------
Description:
When i use a large amount of {{AffineTransformations}} 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}
// BROKEN
context.useFont(FontFace.FONT_TEXT);
for (int i = 0; i < 80; i++) {
context.contentStream.beginText();
context.contentStream.saveGraphicsState();
context.contentStream.transform(new
Matrix(AffineTransform.getTranslateInstance(0, VIEWPORT_TOP - i * 5)));
context.contentStream.showText("XXXXXXXXX");
context.contentStream.restoreGraphicsState();
context.contentStream.endText();
}
// WORKS
context.useFont(FontFace.FONT_TEXT);
for (int i = 0; i < 80; i++) {
context.contentStream.saveGraphicsState();
context.contentStream.beginText();
context.contentStream.transform(new
Matrix(AffineTransform.getTranslateInstance(0, VIEWPORT_TOP - i * 5)));
context.contentStream.showText("XXXXXXXXX");
context.contentStream.endText();
context.contentStream.restoreGraphicsState();
}
{code}
When i skip the transformations or reduce the amount to e.g. 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
independently from the browser.
