Tilman Hausherr commented on PDFBOX-3353:
-----------------------------------------
Some thoughts:
- PDSquareAnnotationTest.java tests itself, i.e. it tests a file that is
already there, not a file where the appearance stream is missing
- you used a different strategy in the square annotation handler to create the
AP than I did... yours is probably better, as it requires less calculations in
the code
- something must be done about that double content stream code, that would be
the "shared implementation" you mention
- appearance handlers should have some common code in the base class.
{{generateNormalAppearance}} has only 3 lines that are specific for this
annotation, all the rest could be common
- why is the PDAppearanceContentStream separated from the PDDocument, i.e. not
using any scratch file settings from it? Could this become a problem or is this
not relevant?
- why is that formatDecimal important?
