virtual void VRS::GIFWriter::write	(	SharedObj *	obj,
		const std::string &	filename
	)			const [virtual]

The GIF writer can handle single images (3 or 4 layers or palette) and iterators over images.

If an Iterator< SO<Image> > is passed to the writer, all images are written into one animated gif file. In that case, frame rate and repeat count specified while construction is used.

Implements VRS::ObjectWriter.

const [virtual]

Format name is "GIF file format", and suffix is "gif".

Implements VRS::ObjectWriter.

static void VRS::GIFWriter::writeFile	(	Image *	image,
		const std::string &	filename
	)			[static]

Write the image as GIF file.

VRS::GIFWriter::VRS_TYPEINFO	(	GIFWriter	,
		ObjectWriter
	)

> for this method, no GIFWriter instance is necessary. But only one image per file can be written. To create an animated gif, use write() instead.
