Hi Jan,

You write english well.  Do not be sorry :)

The mapscript module now lacks a method to iterate over the formats
in mapObj.formats.  The most likely names for built-in formats are

['gif', 'png', 'png24', 'jpeg', 'wbmp', 'swf', 'pdf', 'imagemap']

to find out what you have in the map, you do something like this:

formats = []
for fmtname in ['gif', 'png', 'png24', ...]:
	format = mymap.getOutputFormatByName(fmtname)
     if format:
         formats.append(format)

In the future, we should probably have a getOutputFormat() method
that works like getLayer() and that would allow

     formats = [mymap.getOutputFormat(i) for i in 
range(maymap.numoutputformats)]

but this will not be available until the 4.4 release at the soonest.

cheers,
Sean
