title: Android - What is outputX/outputY and aspectX/aspectY when crop an image from gallery or camera?
body: <p>I read a lot of posts about cropping an image from gallery or camera, and I know outputX/outputY refers to the size of the output/cropped image. However, nobody ever explained what does aspectX/aspectY do? And what is the unit of outputX/outputY? Is it <code>dp</code>?</p>
