		int	quality
	)

Constract a JpegOutput for writing to an IOChannel.

Parameters

out	The gnash::IOChannel to write the image to
width	The width of the resulting image
height	The height of the resulting image.
quality	The quality of the created image, from 1-100.

create()

std::unique_ptr< Output > gnash::image::JpegOutput::create ( std::shared_ptr< IOChannel >  out, size_t  width, size_t  height, int  quality  )

static

Create a JpegOutput, transferring ownership to the caller.

Parameters

out	The gnash::IOChannel to write the image to
width	The width of the resulting image
height	The height of the resulting image.
quality	The quality of the created image, from 1-100.

writeImageRGB()

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.

writeImageRGBA()

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.
