I have a better idea that I'll commit next week: pass the rectangle to
isValidAppearanceStream() and check whether the width / height difference isn't
larger than 1.
{code:java}
private static boolean isValidAppearanceStream(PDRectangle rect,
PDAppearanceEntry appearance)
{
if (appearance == null)
{
return false;
}
if (!appearance.isStream())
{
return false;
}
PDRectangle bbox = appearance.getAppearanceStream().getBBox();
if (bbox == null)
{
return false;
}
if (Math.abs(rect.getWidth() - bbox.getWidth()) > 1 ||
Math.abs(rect.getHeight() - bbox.getHeight()) > 1)
{
// PDFBOX-6223: don't like it if bbox and rectangle are of very
different sizes
return false;
}
return Math.abs(bbox.getWidth()) > 0 && Math.abs(bbox.getHeight()) > 0;
}
{code}
The logic of checking if an appearance already exists has been there since at
least 2014, although there have been changes to check that it is valid, so this
change keeps the spirit of the implementation.
