Fixed form field and annotation appearance generation to match handling by Acrobat Reader [USD-27].

Creator
AddPagehandling updated to work better when applying creator content on top of rotated pages etc. [USD-20]
Makes it much more powerful to use the creator to apply content on top of arbitrary PDF files. The user can rely on the upper left corner always being in upper-left corner and consistent orientation with a PDF viewer.
NOTE: Could lead to strange results for users already manually accounting for page rotations with own code. Recommend testing before going into production.
v3.12.3
v3.12.2
This patch version 3.12.2 release of UniPDF contains the following fixes:
Fixes
- Fix in form field loading, better logic for differentiating non-terminal and terminal fields. Now properly handles linked fields.
- Further improvements in table processing and extraction in the extractor package
NOTE: The form field handling has been updated quite fundamentally but we have taken care to avoid regressions and done quite extensive testing. We recommend testing your code well while upgrading, especially if it works with fields.
v3.12.1
v3.12.0
UniPDF 3.12.0 contains both new features/enhancements (additions to export surface) as well as fixes.
New features and enhancements
- Added document timestamp signature handler option, which enables setting a fixed signature size instead of estimating it through the handler. This can save an extra call to the signature handler (and an extra API call if using an external handler).
Example:
sigLen := 6000 // Reserve 6000 bytes for signature.
handler, err := sighandler.NewDocTimeStampWithOpts(
testTimestampServerURL,
crypto.SHA512,
&sighandler.DocTimeStampOpts{SignatureSize: sigLen},
)
Fixes
- Improved page normalization function:
pdfutil.NormalizePage. Now takes MediaBox and CropBox into account.
Updated documentation forcreatorAddPagefunction to recommend callingpdfutil.NormalizePageprior to adding a page to avoid any surprising offsets or rotations due to some non-default settings. - Fixes in image handling, particularly regarding transparency. There was a regression in transparency handling from updated image handling in v3.10.0, which this corrects, as well as we have much expanded our test coverage to better cover different kinds of images.
