void gnash::image::JpegOutput::writeImageRGB

(

const unsigned char *

rgbData

)

[virtual]

Write RGB image data using the parameters supplied at construction.

Parameters:

rgbData

The raw RGB image data to write as a JPEG.

Implements gnash::image::Output.

void gnash::image::JpegOutput::writeImageRGBA

(

const unsigned char *

rgbaData

)

[virtual]

Write RGBA image data using the parameters supplied at construction.

Note: transparency is ignored because JPEG doesn't support it!

Parameters:

rgbaData

The raw RGBA image data to write as a JPEG.

Reimplemented from gnash::image::Output.
