Figure Properties - SERC

Field Value
alpha Returns 1 if the format has an alpha channel, 0
otherwise
description A text description of the file format
imformats
Note The values for the isa, info, read, and write fields must be functions
on the MATLAB search path or function handles.
formats = imformats('fmt') searches the known formats in the MATLAB
file format registry for the format associated with the filename extension
'fmt'. If found, imformats returns a structure containing the characteristics
and function names associated with the format. Otherwise, it returns an empty
structure.
formats = imformats(format_struct) sets the MATLAB file format registry
to the values in format_struct. The output structure, formats, contains the
new registry settings.
Caution Using imformats to specify values in the MATLAB file format
registry can result in the inability to load any image files. To return the file
format registry to a working state, use imformats with the 'factory' setting.
formats = imformats('factory') resets the MATLAB file format registry to
the default format registry values. This removes any user-specified settings.
Changes to the format registry do not persist between MATLAB sessions. To
have a format always available when you start MATLAB, add the appropriate
imformats command to the MATLAB startup file, startup.m, located in
$MATLAB/toolbox/local on UNIX systems, or $MATLAB\toolbox\local on
Windows systems.
