ufoProcessSetRenderPassMode

    void ufoProcessSetRenderPassMode(
       ufoProcess process_instance,
       int pass_number,
       ufoPassMode pass_mode);

Refer to the following table for command descriptions:

Command | Description
    pass_number
| pass for which the mode is being set
    ufoPassMode
    ufoHorizontalPass
| horizontal line scanning (default)
    ufoVerticalPass
| vertical line scanning

ufoProcessSetRenderPassMode sets the rendering of a particular pass to be either horizontal (the default) or vertical.

If the pass mode is set to ufoVerticalPass then the X and Y arguments passed to UFO render user functions are swapped for that pass.

ufoProcessSetRenderPassMode may be called within ufoProcessDefine to affect all renders, or within ufoProcessPreRender to affect the subsequent render.
