When the length of the original bytes is not a multiple of 4, a special rule is used for round up. The Adobe's ASCII85 implementation is slightly different from its original in handling the last characters. r!uU!z>Lzs~TN)iterbytesordstructpackstrrange)rnboutic_s O/var/www/html/test/engine/venv/lib/python3.12/site-packages/pdfminer/ascii85.py ascii85decoder s IA C $Z 1$K 9d FAB#a&2+&AAvv{{4++ A $Y6 !3q6 !6 ; C $Yq1u$AB A$v{{4+Ga!e44  J#" Jrs ([a-f\d]{2})s#^(?:[a-f\d]{2}|\s)*([a-f\d])[\s>]*$cdtdtfd}d}tj|D] }|||z }tj |}|r|||j ddzz }|S)aASCIIHexDecode filter: PDFReference v1.4 section 3.3.1 For each pair of ASCII hexadecimal digits (0-9 and A-F or a-f), the ASCIIHexDecode filter produces one byte of binary data. All white-space characters are ignored. A right angle bracket character (>) indicates EOD. Any other characters will cause an error. If the filter encounters the EOD marker after reading an odd number of hexadecimal digits, it will behave as if a 0 followed the last digit. xrc2t|d}t|fS)N)intr)r rs rdecodezasciihexdecode..decode;s 2JaT{rrr 0)rhex_refindalltrail_researchgroup)rr$rr ms rasciihexdecoder,1sv%E C ^^D ! vay A vaggaj4'(( Jr) __doc__rerrrcompile IGNORECASEr&r(r,rrr2si  %B $bmm 4 2::=r}} M5r
