Contradictory wording of cl_image_desc specification
Description of image_row_pitch (the same refers to image_slice_pitch) seems mutually contradictory. First spec says:
The image_row_pitch must be zero if ... . If image_row_pitch is zero and the image is created from an external memory handle, then the image row pitch is implementation-defined.
which implies that in some circumstances image_row_pitch may be zero, in others it must be zero. In the same paragraph spec says:
The image row pitch must be ≥ image_width × the size of an image element in bytes, and must be a multiple of the size of an image element in bytes.
Shouldn't this sentence begin with: "Otherwise, the image pitch must ..." ?
Good point. The intent as I understand it is that if row pitch is 0, and the image is an imported handle, then it is implementation defined. If it is imported and non-zero, then it is interpreted as a linear row-major order image.
