NAME

       xyflat - compute hierarchical coordinates

SYNOPSYS

       #include "mph.h"
       void xyflat(xout, yout, x, y, xins, yins, x1, y1, x2, y2, trsf)
       long ∗xout, ∗yout;
       long x, y;
       long xins, yins;
       long x1, y1, x2, y2;
       char trsf;

PARAMETERS

       xout, yout          Values  filled by the function call, return values, that represent coordinates of the
                           point in the figure

       x, y                Coordinates of a point in the instance

       xins, yins          Coordinates of the lower left corner of the instance

       x1, y1, x2, y2      Coordinates of the abutment box of the model of the instance

       trsf                Geometrical operation applied to the instance

DESCRIPTION

       xyflat computes coordinates relative to a model of instance in order to give them in figure  coordinates,
       taking care of the transformation performed on the instance.
       This function is very useful when flattening, or getting coordinates of an object belonging to an istance
       at figure level.
       Care must be taken that the  x1,  y1,  x2,  y2  parameters  are  not  the  current  figure  abutment  box
       coordinates, but the instance model abutment box coordinates.

EXAMPLE

       #include "mph.h"
       long GET_CON_X(insname, conname, index)
       char ∗insname, ∗conname;
       long index;
       {
       phfig_list ∗ptfig; /∗ pointer on model of instance called insname ∗/
       phins_list ∗ptins; /∗ pointer on instance called insname ∗/
       phcon_list ∗ptcon; /∗ pointer on the conname called con inside ptins ∗/
       long x_con, y_con; /∗ return values, y_con here for beauty ∗/
          ptins = getphins(WORK_PHFIG, insname);
          ptfig = getphfig(ptins->FIGNAME, 'P');
          ptcon = getphcon(ptfig, conname, index);
          xyflat(&x_con, &y_con, ptcon->XCON, ptcon->YCON,
             ptins->XINS, ptins->YIINS,
             ptfig->XAB1, ptfig->YAB1, ptfig->XAB2, ptfig->YAB2,
             ptins->TRANSF);
          return x_con;
       }
