A Wave question:

Does anyone know if it is possible to specify
the size of images when using the CGM device?
The size and position qualifiers, whether they are
specified in normal, data or device coordinates of
the TV command do not seem to work when using the
CGM driver. For example, with a 512 x 512 image,

set_plot,'cgm'
device,metafile_type='binary'
tv,image,xsize=.5,ysize=.5,/normal

and

set_plot,'cgm'
device,metafile_type='binary'
tv,image,xsize=1000,ysize=1000,/device

Do not seem to produce different output.
Any suggestions?
