  12 # This file houses conversion information for the preferences file.
  13
  14 # The converter functions take a line as argument and return a list:
  15 #       (Bool, NewLine),
  16 # where the Bool says if  we've modified anything and the NewLine is
  17 # the new line, if so, which will be used to replace the old line.
  18
  19 # Incremented to format 2, r39670 by jrioux
  20 #   Support for multiple file extensions per format.
  21 #   No conversion necessary.
  22
  23 # Incremented to format 3, r39705 by tommaso
  24 #   Support for file formats that are natively (g)zipped.
  25 #   We must add the flag zipped=native to formats that
  26 #   were previously hardcoded in the C++ source: dia.
  27
  28 # Incremented to format 4, r40028 by vfr
  29 #   Remove support for default paper size.
  30
  31 # Incremented to format 5, r40030 by vfr
  32 #   Add a default length unit.
  33 #   No conversion necessary.
  34
  35 # Incremented to format 6, r40515 by younes
  36 #   Add use_qimage option.
  37 #   No conversion necessary.
  38
  39 # Incremented to format 7, r40789 by gb
  40 #   Add mime type to file format
  41
  42 # Incremented to format 8, by rgh
