 Priority:  major                     |   Milestone:  6.4.0                    
Component:  Raster                    |     Version:  svn-develbranch6         
 Keywords:  i.fft, r.mfilter, i.ifft  |    Platform:  Unspecified

 # fft of some raster image[[BR]]
 i.fft in=a real=a_real imaginary=a_imaginary

 # do something with the real_fft_image, e.g. r.mfilter[[BR]]
 r.mfilter in=a_real filter=some_filter out=a_real_filtered

 # perform i.ifft[[BR]]
 i.ifft real=a_real_filtered imaginary=a_imaginary
 output=a_via_fft_filtered

 ERROR: Unable to open real-image in the 'cell_misc' directory. Raster map
 probably wasn't created by i.fft[[BR]]


 # questions
   Is it fair enough to ask for this support?[[BR]]
   Or is there a reason why _r.mfilter_ alters the i.fft-products in such a
 way that _i.ifft_ can't handle?
