Although it isn't obvious at first, in the Android Instagram app you can (after editing a photo) go back to the photo roll to view an old image. Then a frame appears with drag handles on the side; you can move the frame and resize it by dragging the handles, allowing you to crop to any part of the image.
How do I do this on Android? Is this a standard feature, is there a similar open source library?
take look at this project.
https://github.com/naver/android-imagecropview
This project is for imagecropview like instagram
Is this along the lines of what you want?

I want to scan a image to detect the colour and text from the image. I have found OCR tutorial to do the same and implement it. But I don't want to capture image just want to scan image and detect text. Is there any library with which I can detect the text and colour from image when I scan ?
Thanks!
You could take a look at google's Vision API. It has said feature and is fairly easy to use.
Here, I have some more examples at below link for OCR related codes:

On Android, I have .png images added as a resource in my /res/ folder.
Question: I want to display an image from the resource filling a screen, but allowing the user to pinch-to-zoom it. What UI component do I use? An ImageView? A WebView?
http://www.zdnet.com/blog/burnette/how-to-use-multi-touch-in-android-2-part-6-implementing-the-pinch-zoom-gesture/1847
How can I get zoom functionality for images?
Put your image in the assets folder, and point the WebView to it. The WebView will do everything for you, in terms of pinch to zoom functionality.
