Revision 491, 7.7 kB (checked in by jerome, 17 years ago)

Major code cleaning. Now clearer, although probably a bit slower since
a file can be opened several times.
Now universal line opening mode is only used when needed (PS, PDF and plain
text), and binary opening mode is used for the other formats.
This mean we will be able to remove mmap calls wherever possible, finally.

39    - Added a minimal parser for ESC/PAGES03 style documents.
40   
41    - Fixed another problem in the code handling the output of Canon's

54   
55  * 2.17 :
56 
57    - Fixed problems in the handling of PJL number of copies (COPIES= and QTY=)

61 
62    - Fixed a problem in the PCL3/4/5 parser to accomodate line based
63      report generators which expect the printer to skip to next page
64      based on lines per page instead of sending a specific command.
65     
66  * 2.15 :
67   
68    - Fixed a regexp in the PDF parser which caused some files to be
69      incorrectly accounted for.

83      respectively for a grayscale page and a coloured page.
84 
85  * 2.12 :
