Functions
void	VuoImage_free (void *texture)
	Decrements the retain count of the OpenGL Texture Object associated with the specified VuoImage, and frees the texture VuoImage struct.
VuoImage	VuoImage_make_internal (unsigned int glTextureName, unsigned int glInternalFormat, unsigned long int pixelsWide, unsigned long int pixelsHigh)
	Helper for VuoImage_make and VuoImage_makeClientOwned.
VuoImage	VuoImage_make (unsigned int glTextureName, unsigned int glInternalFormat, unsigned long int pixelsWide, unsigned long int pixelsHigh)
	Returns a new VuoImage structure representing the specified glTextureName.
VuoImage	VuoImage_makeClientOwned (unsigned int glTextureName, unsigned long int pixelsWide, unsigned long int pixelsHigh, VuoImage_freeCallback freeCallback, void *freeCallbackContext)
	Returns a new VuoImage structure representing the specified glTextureName.
VuoImage	VuoImage_makeFromBuffer (unsigned char *pixels, unsigned int format, unsigned int pixelsWide, unsigned int pixelsHigh)
	Uploads the specified pixel data to the GPU and returns a new VuoImage referencing it.
static void	VuoImage_deleteImage (VuoImage image)
	Deletes image's GL texture.
VuoImage	VuoImage_makeColorImage (VuoColor color, unsigned int pixelsWide, unsigned int pixelsHigh)
	Makes a solid-color image.
VuoImage	VuoImage_makeCopy (VuoImage image)
	Returns a new texture copy of the passed image.
VuoRectangle	VuoImage_getRectangle (const VuoImage image)
	Returns a rectangle (in Vuo Coordinates) at the origin, with width 2 and height matching the image's aspect ratio.
VuoImage	VuoImage_valueFromJson (json_object *js)
	Decodes the JSON object js to create a new value.
json_object *	VuoImage_jsonFromValue (const VuoImage value)
	Encodes value as a JSON object.
json_object *	VuoImage_interprocessJsonFromValue (const VuoImage value)
	Returns a JSON object containing an interprocess handle for the specified texture.
char *	VuoImage_summaryFromValue (const VuoImage value)
	A brief summary of the contents of this texture.
