NAMEglReadBuffer, glNamedFramebufferReadBuffer − select a color buffer source for pixels
C SPECIFICATIONvoid glReadBuffer(GLenum mode); void glNamedFramebufferReadBuffer(GLuint framebuffer, GLenum mode);
PARAMETERSframebuffer Specifies the name of the framebuffer object for glNamedFramebufferReadBuffer function​. mode Specifies a color buffer​. Accepted values are GL_FRONT_LEFT, GL_FRONT_RIGHT, GL_BACK_LEFT, GL_BACK_RIGHT, GL_FRONT, GL_BACK, GL_LEFT, GL_RIGHT, and the constants GL_COLOR_ATTACHMENTi​.
DESCRIPTIONglReadBuffer specifies a color buffer as the source for subsequent glReadPixels(), glCopyTexImage1D(), glCopyTexImage2D(), glCopyTexSubImage1D(), glCopyTexSubImage2D(), and glCopyTexSubImage3D() commands​. mode accepts one of twelve or more predefined values​. In a fully configured system, GL_FRONT, GL_LEFT, and GL_FRONT_LEFT all name the front left buffer, GL_FRONT_RIGHT and GL_RIGHT name the front right buffer, and GL_BACK_LEFT and GL_BACK name the back left buffer​. Further more, the constants GL_COLOR_ATTACHMENTi may be used to indicate the ith color attachment where i ranges from zero to the value of GL_MAX_COLOR_ATTACHMENTS minus one​. Nonstereo double−buffered configurations have only a front left and a back left buffer​. Single−buffered configurations have a front left and a front right buffer if stereo, and only a front left buffer if nonstereo​. It is an error to specify a nonexistent buffer to glReadBuffer​. mode is initially GL_FRONT in single−buffered configurations and GL_BACK in double−buffered configurations​. For glReadBuffer, the target framebuffer object is that bound to GL_READ_FRAMEBUFFER​. For glNamedFramebufferReadBuffer, framebuffer must either be zero or the name of the target framebuffer object​. If framebuffer is zero, then the default read framebuffer is affected​.
ERRORSGL_INVALID_ENUM is generated if mode is not one of the twelve (or more) accepted values​. GL_INVALID_OPERATION is generated if mode specifies a buffer that does not exist​. GL_INVALID_OPERATION is generated by glNamedFramebufferReadBuffer if framebuffer is not zero or the name of an existing framebuffer object​.
