Patch 1.25.1, 2015-07-20
- Fix bug when parsing inline images. Occurred when merging
certain pages with inline images
- Fixed type error when creating outlines by utilizing the
isString() test

------------------------
BUGFIXES:
- Added Python 3 algorithm for ASCII85Decode. Fixes issue when
reading reportlab-generated files with Py 3 (jerickbixly)
- Recognize more escape sequence which would otherwise throw an
exception (manuelzs, robertsoakes)
- Fixed overflow error in generic.py. Occurred
when reading a too-large int in Python 2 (by Raja Jamwal)
- Allow access to files which were encrypted with an empty
password. Previously threw a "File has not been decrypted"

- Recognize abbreviated filter names (AlmightyOatmeal and
Matthew Weiss)
- Copy decryption key from PdfFileReader to PdfFileMerger.

of a file stream. Threw a "Stream has ended unexpectedly"
exception (speedplane)
FEATURES:
- Initial work on a test suite; to be expanded in future.
Tests and Resources directory added, README updated (robertsoakes)
- Added document cloning methods to PdfFileWriter:
appendPagesFromReader, cloneReaderDocumentRoot, and

- Added method for writing to form fields: updatePageFormFieldValues.
This will be enhanced in the future. See official documentation
(robertsoakes)
- New addAttachment method. See documentation. Support for adding
and extracting embedded files to be enhanced in the future
(moshekaplan)
- Added methods to get page number of given PageObject or
Destination: getPageNumber and getDestinationPageNumber.
