show and save the big size image

Hi everyone,

1. Is there anyone knows how to show the big size image?

Let say I have 2000 x 3000 pixel image. When I tried to show up used the "imshow" function, there will be any warning message

Warning: Image is too big to fit on screen; displaying at 17%

And I need to display all part image on screen (use the scroll panel)

2. How to save/export this big size image(1) without white border? So I can get 2000x3000 output image.

Thanks in advance

Does you monitor have 2000 x 3000 pixels? If not there are different solutions:

• The image is scaled automatically e.g. by using the image() command.
• The image is scaled manually, see imresize.
• The image must be scrolled.

You can use imwrite to export the image array directly. This is much better than re-importing the image from the figure again.
