Class ScreenShot

java.lang.Object

io.cine.android.streaming.ScreenShot

public class ScreenShot
extends java.lang.Object

Created by lgorse on 2/11/15. This class defines the basic configuration required for a screenshot. The relevant variables are the filepath,the file prefix and the scale. FilePath means the folder path. The file name is an aggregate of the prefix, the timestamp of Now() and a png extension. Scale is important for space management - it allows the user to have some control over how much space his thumbnails are going to take.

The comments above are directly from the Grafika library. I shifted a lot of its content to this section so it makes sense to have it as a reminder. This method saves the contents of a Bytebuffer to an output stream, and generates a bitmap from that. It also applies any scaling and rotates/mirrors the image to take into account OpenGL scaling.

Parameters:

buf - must be rewound prior to being passed to this method. Essentially buff must be declared, and GLReadPixels called, then the buffer rewound Then it is ready to be passed to this method. It's important to do these preparation steps in an EGL context, and not on their own. That's why we make sure not to include them here. Maybe not a good idea?

width -

height -

Throws:

java.io.IOException
