Sets the pixel values in an image.
The function image-access-transfer-to-image sets the pixel values in an image object from the values in a corresponding Image Access object image-access .
image-access must be an Image Access object returned by make-image-access.
Notionally mage-access-transfer-to-image transfers the pixel data from image-access to the window system, though it might do nothing on platforms where the window system allows direct access to the pixel data.
