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 L/var/www/html/ai-engine/env/lib/python3.11/site-packages/pdfminer/ascii85.py ascii85decoder s* IA C $ZZ 1$KK 199d FAB#a&&2+&AAvvv{4+++ A $YY6663q66666 ; CC $YY 5q1u$$AB AAv{4++Ga!eG44 E  Jrs ([a-f\d]{2})s#^(?:[a-f\d]{2}|\s)*([a-f\d])[\s>]*$cdtdtfd}d}t|D]}|||z }t|}|r$|||ddzz }|S)a ASCIIHexDecode 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. xrcBt|d}t|fS)N)intr)r rs rdecodezasciihexdecode..decode=s 2JJaT{{rrr 0)rhex_refindalltrail_researchgroup)rr$rr ms rasciihexdecoder,2s%E C ^^D ! ! vvayyA) vvaggajj4'((( Jr) __doc__rerrrcompile IGNORECASEr&r(r,rrr2s  %D $bm 4 4 2:=r} M M5r
