[pdf-devel] ASCII85Decode implementation

[Cirilo Bernardo]

Is there still work being done on the ASCII85Decode filter or is this
considered finished and should be debugged?

I have found a number of problems in the implementation:
1. An incomplete quintet at the end is not processed
2. The EOD sequence is "~>", NOT '~'; if "~>" is not found at the end,
this is an error
3. The quintet is not tested for the overflow condition (> 2^32 -1)
before conversion
4. The final quintet, if incomplete, is not tested for the condition
(count > 1).
