Description
Transfers multi-valued (8- or 16-bit/pixel) source data to any quadrilateral rendering coordinates.
The source is always scanned horizontally, but diagonal scanning may be used in the drawing,
depending on the shape. In diagonally-scanned drawing, double-writing occurs to fill in gaps.
When repeated source referencing is selected as a rendering attribute (STYL = 1), the source is not
enlarged or reduced, but is referenced repeatedly.
When work referencing is selected as a rendering attribute (WORK = 1), transfer is performed while
referencing work area data for the same coordinates as the rendering coordinates.
The multi-valued source is referenced, and enlargement and reduction performed, taking in
multiples of 8 pixels in the multi-valued source coordinate X-direction as one unit. TDX must
therefore be specified in multiples of 8 pixels in order for multi-valued source referencing to be
carried out correctly.
