icetSetContext(3) IceT Reference icetSetContext(3)NAME
icetSetContext -- changes the current context.
Synopsis
#include <IceT.h>
void icetSetContext( IceTContext context );
Description
The icetSetContext function sets the IceT state machine to work with the context defined by context and the state associated with it. Fur-
ther calls to IceT functions will operate based on the state encapsulated in context. Changing the state of the context is a fast opera-
tion.
Errors
ICET_INVALID_VALUE
context is not valid.
Warnings
None.
Bugs
None known.
Notes
The behavior of icetSetContext is somewhat indeterminate if context is not valid. Usually, an ICET_INVALID_VALUE error will be raised, but
it is possible that the context will be set to some other context.

icetGLSetReadBuffer(3) IceT Reference icetGLSetReadBuffer(3)NAME
icetGLSetReadBuffer -- set OpenGL buffer for images
Synopsis
#include <IceTGL.h>
void icetGLSetReadBuffer( GLenum mode );
Description
Set the OpenGL buffer from which to read images to composite. After the draw callback (specified by icetGLDrawCallback) returns, IceT grabs
the rendered image from the OpenGL buffer specified by mode. This buffer is also used to write back fully composited images if the
ICET_GL_DISPLAY option is on.
mode is an OpenGL value that specifies the buffer. It is passed to glReadBuffer and glDrawBuffer. Accepted values are GL_FRONT, GL_BACK,
GL_LEFT, GL_RIGHT, GL_FRONT_LEFT, GL_FRONT_RIGHT, GL_BACK_LEFT, GL_BACK_RIGHT, and any of the GL_AUXi identifiers.
The current read buffer used is stored in the ICET_GL_READ_BUFFER state variable. The default value is GL_BACK.
Errors
ICET_INVALID_OPERATION
icetGLInitialize has not been called for this IceT context.
ICET_INVALID_ENUM
mode is not a known OpenGL buffer identifier.
Warnings
None.
Bugs
The check of mode is perfunctory. It just checks mode against a list of known buffers. It does not check to see if the buffer actually
exists or for any other buffers that might be defined in an OpenGL extension.
