Cliff and others, It makes sense when I look at what you are doing and when I make random 4 x6 x1 matrices I am able to deal with them as images without a problem. I tried adding a trailing axis of length 1 and I called it FINAL_IMAGE. see the code below:
ID600x600x1=: 600 600 1 $ 1 , zeros6 NB. 600 zeros appended $ID600x600x1 600 600 1 view_image ID600x600x1 600 600 1 FINAL_IMAGE=:FINAL dot ID600x600x1 $FINAL_IMAGE 400 600 1 BW256 view_data FINAL_IMAGE NB. This is exactly what I want as a JPEG 600 400 view_image FINAL_IMAGE NB. Not working properly 400 600 1 NB. and these are the following errors I received: (,:"1 FINAL_IMAGE) write_image 'imagefilename.jpg' |domain error: memw | (,m) memw addr,0,sz 85 0 1 (,:"0 FINAL_IMAGE) write_jpeg 'test_image.jpg' |domain error: memw | (,m) memw addr,0,sz Do the errors I recieved help? If not, I just attached my code. Sorry if it is against forum rules to attach my code or files. It should operate on any 400x600 image, the one I used was just named lion.jpg Brandon ******************************************************************************************* image3 has 4 allowed image data types, but matrices are not on the list for images; view_image adds one more type (filenames) http://ww2.lafayette.edu/~reiterc/j/image3help/image3.html view_data is more ad hoc, better to work with view_image and write_image etc. Add a trailing axis of length 1 is what you need, I think (,:"1 FINAL) write_image 'imagefilename.jpg' or 85 0 1 (,:"1 FINAL) write_image 'imagefilename.jpg' should work . . . .
