i am pretty new on this platform. i am working on a project in which i have to perform following task. 1.) show an image on UIIMageView which is selected from photolibrary.(completed.) 2.) take a UILAbel and show the pixel of selected Image. (That's what i want to know who to do.) 3.) save in photolibrary(completed).

Thanks in advance.

HI you said u want to get the area of the image then what about the periperals means by using gestures u want to get measure the area of the image or you want measure someother way please let me know.

if based on finger moments you want to measure the area ok fine you can by using the locationinview method you can find the gesture starting point location values and gesture ending point locationvalues based on these you can find the area.
