Image1.raw and image2.raw of 1500x15000 size are attached together.
I made an image of 3000x15000 size.
To save this as a raw file,
saveas(img,'image.raw');
I used the code.
"It's not a valid handle." ' The phrase came out and was not created.

Ran in:
yes，sir，may be use fwrite/fread to make raw file，such as
im = imread('rice.png');
figure; imshow(im, []);
fid = fopen('a.raw','w');
fwrite(fid,im);
fclose(fid);
fid2 = fopen('a.raw');
im2 = fread(fid2);
fclose(fid2);
im2 = reshape(im2, 256, 256);
figure; imshow(im2, []);
