Deprecated CGGLContext Functions

A function identified as deprecated has been superseded and may become unsupported in the future.

Deprecated in OS X v10.6

CGGLContextCreate

Creates a Quartz graphics context from an OpenGL context. (Deprecated in OS X v10.6.)

CGContextRef CGGLContextCreate (
   void *glContext,
   CGSize size,
   CGColorSpaceRef colorspace
);

Parameters

glContext: The context that the OpenGL system uses to manage OpenGL drawing.
size: The dimensions of the OpenGL viewport rectangle.
colorspace: An RGB color space that serves as the destination space when rendering device-independent colors. If NULL, Quartz uses the default RGB color space. Quartz retains the color space you pass in; on return, you may safely release it.

Return Value

A new Quartz graphics context. You are responsible for releasing this object by calling CGContextRelease.

Discussion

The use of this function is not recommended.

Creates a Quartz context from the OpenGL context glContext. The context establishes an OpenGL viewport rectangle with dimensions specified by the size parameter by calling glViewport(3G). If non-NULL, the colorspace parameter should be an RGB profile that specifies the destination space when rendering device-independent colors.

Availability

Available in OS X version 10.3 and later.
Deprecated in OS X v10.6.

Declared In

CGGLContext.h

CGGLContextUpdateViewportSize

Updates the size of the viewport associated with an OpenGL context. (Deprecated in OS X v10.6.)

void CGGLContextUpdateViewportSize (
   CGContextRef c,
   CGSize size
);
