void VuoImageRenderer_destroy

(

VuoImageRenderer

ir

)

Destroys and deallocates the image renderer.

This function may be called from any thread.

Todo:

VuoImage VuoImageRenderer_draw	(	VuoImageRenderer	ir,
		VuoGlContext	glContext,
		VuoShader	shader,
		unsigned int	pixelsWide,
		unsigned int	pixelsHigh
	)

Produces a new VuoImage by rendering shader.

This function may be called from any thread. (However, the caller is responsible for ensuring that the GL context is not used simultaneously on multiple threads.) (Additionally, the caller is responsible for ensuring that the same VuoImageRenderer is not used simultaneously on multiple threads.)

unsigned long int VuoImageRenderer_draw_internal	(	VuoImageRenderer	ir,
		VuoGlContext	glContext,
		VuoShader	shader,
		unsigned int	pixelsWide,
		unsigned int	pixelsHigh,
		bool	outputToIOSurface
	)

Helper for VuoImageRenderer_draw().

VuoImageRenderer VuoImageRenderer_make

(

void

)

Creates a reference-counted object for rendering a VuoImage.

This function may be called from any thread.
