 shows you the accessors to use :)

 This is a subclass of OpenCL::Mapped, representing mapped images.

+=item $pixels = $mapped->width
+=item $pixels = $mapped->height
+=item $pixels = $mapped->depth
+Return the width/height/depth of the mapped image region, in pixels.
 =item $bytes = $mapped->row_pitch
 =item $bytes = $mapped->slice_pitch
 Return the row or slice pitch of the image that has been mapped.
+=item $bytes = $mapped->element_size
+Return the size of a single pixel.
+=item $data = $mapped->get_row ($count, $x=0, $y=0, $z=0)
+Return C<$count> pixels from the given coordinates. The pixel data must
+be completely contained within a single row.
+If C<$count> is C<undef>, then all the remaining pixels in that row are
+returned.
+=item $mapped->set_row ($data, $x=0, $y=0, $z=0)
+Write the given pixel data at the given coordinate. The pixel data must
+be completely contained within a single row.
