    GL_CHROMIUM_image is required.

Overview

    This extension provide a mechanism for creating a GpuMemoryBuffer
    backed image resource.

Issues

    None

New Tokens

    Accepted by the <usage> parameter of CreateGpuMemoryBufferImageCHROMIUM:

        MAP_CHROMIUM 0x78F1
        SCANOUT_CHROMIUM 0x78F2

New Procedures and Functions

    GLuint CreateGpuMemoryBufferImageCHROMIUM(GLsizei width,
                                              GLsizei height,
                                              GLenum internalformat,
                                              GLenum usage)

    Create a GpuMemoryBuffer backed image with width equal to <width>
    and height equal to <height> and format equal to <internalformat>.

    Returns a unique identifier for the image that could be used in
    subsequent operations.

    INVALID_VALUE is generated if <width> or <height> is nonpositive.

    INVALID_ENUM is generated if <internalformat> is not one of
    RGB or RGBA.

    INVALID_ENUM is generated if <usage> is not one of
    MAP_CHROMIUM or SCANOUT_CHROMIUM.

Errors

    None.

New State

    None.
