project.android.imageprocessing.output.JPGFileEndpoint
- All Implemented Interfaces:
- GLTextureInputRenderer
public class JPGFileEndpoint
- extends GLRenderer
- implements GLTextureInputRenderer
A JPG image renderer extension of GLRenderer.
This class accepts a texture as input and renders it to a jpeg image file.
Images will be saved to file every time the texture is updated. If increment is on, it will save the file with the
given base name and an added number in the format "filePath%d.jpg". The filepath is the path and name of the image
file that should be written to (".jpg" will be appened automatically). This class does not
handle displaying to the screen; however it does use the screen to render to the video recorder, so if display is not
required the opengl context should be hidden. Storing to the camera roll is optional. If it is false, the context is allowed
to be null. Either way the image is written to filePath; however, it will only be visible in the gallery if storing to media is
true. Storing to media may slow down the file writing. Also, if it is true, every image will be stored to the camera roll whether or not increment
is on.
