Description

pinq_ws_tran3 queries the workstation state list and returns values for the following:

•Workstation transformation update state

•Requested workstation window limits in normalized projection coordinate points

•Current workstation window limits in normalized projection coordinate points

•Requested workstation viewport limits in device coordinates

•Current workstation viewport limits in device coordinates

If the application requests a workstation transformation change but Digital PHIGS does not provide it by the time the application calls this function, the workstation transformation update state is PUPD_PEND.
