Just when I thought I was getting a better friend with IDL....
We run IDL on our RS-6000, X-windows.
What I need:
1.Read a graphic file (GIF - TIFF) into IDL and Dispaly it.
2.FFTransform the image and display the result.
I've been reading the information available on this subject in the idl's
user manual. According to this I should be able to do it with the following
command line:
READ_GIF,'/../.../filename.gif',variable1 (read gif image)
If I understand right the image will then be saved in a (byt)array
and should be ready to be FFT processed. BUT IT DOES NOT WORK! What am I doing
wrong? I get all the time a message:
IDL> image1=tiff_read("/u/jairo/img/62-10g.tif")
% Compiled module: TIFF_READ.
% Subscript range values must be >= 0, < size: ENT.
% Execution halted at TIFF_READ_FIELD
</usr/local/lib/idl/lib/data_io/tiff_read.pro( 148)> .
%Called from TIFF_READ </usr/local/lib/idl/lib/data_io/
tiff_read.pro( 242)>.
%Called from $MAIN$ .
Here the image is TIFF and is 256x256 pixels-8bits(grayscale).
CAN ANYBODY TELL ME HOW TO RESOLVE THIS !!!!
