PK_render_viewport_clip_t

typedef int PK_render_viewport_clip_t;

Used in:

PK_TOPOL_render_line_o_t

This typedef controls how entities which lie partially within the given
viewport or viewports are rendered.
If it is set to 'PK_render_viewport_clip_yes_c' then any lines which lie
entirely outside the viewport will not be output and clip information will be
supplied for any lines which cross the viewport boundaries. If the viewports
used are 3D viewports, then any clashes between rendering faces and viewport
faces will result in the generation of a clip line.
If it is set to 'PK_render_viewport_clip_no_c' then all lines associated with
these entities will be output but only if they belong to a face that clashes
with a viewport.
This field can take any one of the following values.
    'PK_render_viewport_clip_no_c'  : no viewport clipping (default)
    'PK_render_viewport_clip_yes_c' : viewport clipping enabled
