Details:

There will be NO grapic output if imshow is used for large images.


img_data = uint8(randn(3072, 4096)*255);
figure(); imshow(img_data)


If the range to display will be reduced, the selected image range will be
shown as expected.


img_data = uint8(randn(3072, 4096)*255);
figure(); imshow(img_data(1:2050,1:4096))


The same for RGB images.
