I have Array of images, which I need to display on the Landscapeand portrait mode.. what I have done is that I have created a Array of images and displaying on the scrollView to see one at a time ..but problem is that When I move to Landscape to portrait or vice versa images get split ...view comes with the half previous image and half next.. this does not happen everytime...I dont know why the images are splitting and not exactly in half ...sometime split in different size..
#define portrait_width1 600.0
#define portrait_height1 600.0
#define landscape_width1 800.0
#define landscape_height1 445.0
