DCL:GRPH1:STPACK: Transformation Functions:List of Subroutines
vx, vy = NumRu::DCL.stftrn(ux,uy) Basic transformation NumRu::DCL.ststrn(itr,cxa,cya,vxoff,vyoff) Sets the parameters for basic transformation tx, ty = NumRu::DCL.stfrot(ux,uy) Rotation of a map coordinate NumRu::DCL.stsrot(theta,phi,psi) Sets the parameters for rotation of a map coordinate rx, ry = NumRu::DCL.stfrad(x,y) Unit transformation of angle NumRu::DCL.stsrad(lxdeg,lydeg) Sets parameters for unit transformation of angle.
There are also routines for inverse transformations with i as the 3rd character in the routine name, and parameter inquiry routines with q as the 3rd character.
