Inputs

framebuffer-rect

a framebuffer-rect

Outputs

image

an image

Word description
Reads the rectangular region framebuffer-rect into a new image. The format of the image is determined by the component-order and component-type of the associated framebuffer-attachment.

Notes
User-created framebuffer objects require OpenGL 3.0 or one of the GL_ARB_framebuffer_object or GL_EXT_framebuffer_object extensions.
