ufoProcessPreRender

void ufoProcessPreRender(
   ufoProcess process_instance,
   int        x1,
   int        y1,
   int        x2,
   int        y2);

Refer to the following table for command descriptions:

x1,y1,x2,y2

This function is optional. If supplied, it is called directly before the rendering of a rectangular region of the UFO process outputs.

When called, all raster inputs and outputs and parameters will be set in the process, such that all their attributes and values can be inquired. ufoProcessPreRender should be supplied if specific data initializations or allocations need to be performed before a render.

If the ufoProcessRenderLine or ufoProcessRenderPixel render function is supplied, performance will improve if parameter values are inquired and copied into some representation in the UFO user data within this function, and then referenced from the user data during rendering.
