|
| -Overview
|
| -
|
| - This extension allows for more efficient uploading of texture data through
|
| - Chromium's OpenGL ES 2.0 implementation.
|
| -
|
| - For security reasons Chromium accesses the GPU from a separate process. User
|
| - processes are not allowed to access the GPU directly. This multi-process
|
| - architechure has the advantage that GPU operations can be secured and
|
| - pipelined but it has the disadvantage that all data that is going to be
|
| - passed to GPU must first be made available to the separate GPU process.
|
| -
|
| - This extension helps the application directly allocate and access texture
|
| - memory.

|
| -
|
| - GLuint CreateImageCHROMIUM (GLsizei width, GLsizei height,
|
| - GLenum internalformat)
|
| -
|
| - Allocate an image with width equal to <width> and height equal
|
| - to <height> stored in format <internalformat>.
|
| -
|
| - Returns a unique identifier for the allocated image that could be used
|
| - in subsequent operations.
|
| -
|
| - INVALID_VALUE is generated if <width> or <height> is nonpositive.
|
| -
|
| - void DestroyImageCHROMIUM (GLuint image_id)
|
| -
|
| - Frees the image previously allocated by a call to CreateImageCHROMIUM.
|
| -
|
| - INVALID_OPERATION is generated if <image_id> is not a valid image id.
|
| -
|
| - void* MapImageCHROMIUM (GLuint image_id, GLenum access)
|
| -
|
| - Returns a pointer to in the user memory for the application to modify
|
| - the image. <access> parameter defines if the user will read or write the
|
| - pixels.
|
| -
|
| - INVALID_OPERATION is generated if <image_id> is not a valid image id.
|
| -
|
| - INVALID_OPERATION is generated if the image was already mapped by a previous
|
| - call to this method.
|
| -
|
| - INVALID_ENUM is generated if <access> is not one of WRITE_ONLY, READ_ONLY
|
| - and READ_WRITE.
|
| -
|
| - void UnmapImageCHROMIUM (GLuint image_id)
|
| -
|
| - Removes the mapping created by a call to MapImageCHROMIUM.
|
| -
|
| - Note that after calling UnmapImageCHROMIUM the application should assume
|
| - that the memory returned by MapImageCHROMIUM is off limits and is no longer
|
| - accessible by the application. Accessing it after calling
|
| - UnmapImageCHROMIUM will produce undefined results.
|
| -
|
| - INVALID_OPERATION is generated if <image_id> is not a valid image id.
|
| -
|
| - INVALID_OPERATION is generated if the image was not already mapped by a
|
| - previous call to MapImageCHROMIUM.
|
| -
|
| - void GetImageParameterivCHROMIUM(GLuint image_id, GLenum pname,
|
| - GLint* params)
|
| -
|
| - Sets <params> to the integer value of the parameter specified by <pname>
|
| - for the image specified by <image_id>. <params> is expected to be
|
| - properly allocated before calling this method.
|
| -
|
| - INVALID_OPERATION is generated if <image_id> is not a valid image id.
|
| -
|
| - INVALID_ENUM is generated if <pname> is not IMAGE_ROWBYTES_CHROMIUM.
