- PDF Engine
- JavaScript actions are not read for annotations and form fields when the JavaScript value is specified as non-String object i.e., Indirect Reference or Stream object in the action dictionary.
- Javascript actions represented as Indirect reference or PDFStream are not parsed resulting in NULL return value.
- Text and shapes are not rendered at correct location when cm transformations and shapes rendering occur between BT (BeginText) and ET (EndText) operations.
- Issue in storing and restoring negative font size resulting in incorrect rotation of the rendered text.
- Multiple text extraction issues related to Type0 and Type3 fonts which is producing incorrect output while converting from PDF to text.
