What's that canvas type?

[matmatmat]

Pls can anybody say to me, what type of canvas or UI component is used in application named: "VirtualSurgery" (or any similar)?
It's a canvas for image, where you can choose a part of it (with any mask) and crop it then.

Or generally, which one component is adapted for moving and zooming with image (like editing after camera shooting)?

Thanks

sry.. here is

there you can select some area of picture by that rectangle and crop it...

That image is a part of iOS SDK just like the background patter for grouped table views. Try this:

1. Open IB, create a view.
2. Click on the view, then in the Inspector window go to attributes and find Background, click the little box on the left.
3. Colors window will show, click the middle button (palettes) then in the Palette dropdown list select iPhone SDK. In the list below look for scrollView TexturedBackground.

So (after this long explanation), it's not a component. You'll have to create and code your own marker to select a portion of the screen.

omg i didn't want to know how to make pattern background

i asked how to code principially that one, you can choose any part of image and crop them of course ...

here's some other example:

(can be selected some part of image and then it's cropped just that part)

Can anybody tell me, which component were used for that (ImageView? ScrollView?)

Like I said in the last sentence, it's not one nor standard component. You'll have to make it yourself. Create a marker view, add gesture recognizers to it (pan to move, pinch to resize) etc.

[matmatmat]

of course i know its not a standard component... i only want to know how to proceed by creating that marker view... what component do you recommend to use, etc..

A UIView.
