# This file houses conversion information for the preferences file.
# The converter functions take a line as argument and return a list:
# (Bool, NewLine),
# where the Bool says if we've modified anything and the NewLine is
# the new line, if so, which will be used to replace the old line.
# Incremented to format 2, r39670 by jrioux
# Support for multiple file extensions per format.
# No conversion necessary.
# Incremented to format 3, r39705 by tommaso
# Support for file formats that are natively (g)zipped.
# We must add the flag zipped=native to formats that
# were previously hardcoded in the C++ source: dia.
# Incremented to format 4, r40028 by vfr
# Remove support for default paper size.
# Incremented to format 5, r40030 by vfr
# Add a default length unit.
# No conversion necessary.
# Incremented to format 6, r40515 by younes
# Add use_qimage option.
# No conversion necessary.
# Incremented to format 7, r40789 by gb
# Add mime type to file format
2012-05-22 12:57:25 +00:00
# Incremented to format 8, 288c1e0f by rgh
# Add "nice" flag for converters
