Hi, I used: print('-dtiff','example.tif') in my code. now, i need to save the image (example.tif) in a specified directory. My code is: baseFileName = sprintf('TEST%d.tif', j); fullFileName = fullfile(pathName, baseFileName); imwrite(example, fullFileName);

but this error occurs: ??? Undefined function or variable 'example' any idea?

tnx, Azi

Why not use print() directly.

print('-dtiff',fullFileName)

My problem with using print is that, i want the resulted image to be saved like this automatically after each running:

TEST1.tif

TEST2.tif

...

that's the reason i used : sprintf('TEST%d.tif', j)- j will be incremented each time.

any suggestion?

tnx

Look in the documentation of IMWRITE: IMWRITE(A, filename) expects A to be an array containing the pixel values. But in your code "example" is not a defined variable.

I assume you want to move the file:

movefile('example.tif', fullFileName);

Most likely Jiang's answer would be better: Sinmply create the picture file at the wnated location directly.
