y axis is reversed

dear all,

when i'm calling images to be shown and write axis on, i found y axis is reversed, i mean if the image is 512x512 ,i found the (x, y) coordinates is (0,512) not (0,0) as it is supposed to be. it starts from high value to low value bottom to top.

how can i solve this problem?

thanks and best regards

Please compare "axis image" to "axis xy" in the documentation, http://www.mathworks.com/help/techdoc/ref/axis.html

thanks alot for replying my question. actually i've tried both axis image and axis xy but no effect on the image.
