Initialize a writer for JPEG images.
imageStage | the image to write from |
quality | sets the JPEG "quality" encoding parameter; this is a value between 0 and 100 |
smoothing | sets the JPEG "smoothing" encoding parameter; this is a value between 0 and 100 |
This function implements the logic for beginning the encoding of the given scene.
The scene must be a valid scene for the underlying image pipeline.
This function is called by write(). Derived classes must implement this function.
scene | the scene to decode and output |
Reimplemented from LTIGeoFileImageWriter.
|
virtual |
This function implements the logic for completing the encoding of the given scene.
This function is called by write(). Derived classes must implement this function.
Reimplemented from LTIGeoFileImageWriter.
|
virtual |
This function implements the logic for actually encoding a given strip of the given scene.
This function is called by write(). Derived classes must implement this function.
stripBuffer | the pixels for the current strip |
stripScene | the scene representing the strip being written |
Implements LTIGeoFileImageWriter.
