§ Output()

gnash::image::Output::Output	(	std::shared_ptr< IOChannel >	out,
		size_t	width,
		size_t	height
	)

inline

Construct an Output for writing to an IOChannel.

Parameters

out	The gnash::IOChannel to write the image to. Ownership is shared.
width	The width of the resulting image
height	The height of the resulting image.

§ writeImageData()

void gnash::image::Output::writeImageData	(	FileType	type,
		std::shared_ptr< gnash::IOChannel >	out,
		const GnashImage &	image,
		int	quality
	)

static

Write the given image to the given IOChannel in a specified format.

Parameters

type	The image format to write in (see GnashEnums.h)
out	The IOChannel to write to.
image	The image to write.
quality	The quality of the image output, from 0..100. Values outside this range will be clamped to the minimum or maxium value. The quality is not used for all formats.
