vqt_fontinfo()                                                          VDI

Syntax

VOID vqt_fontinfo( handle, first, last, dist, width, effects )
WORD handle;
WORD *first, *last, *dist, *width, *effects;

Function      vqt_fontinfo() returns information regarding the current
              text font.

Opcode        131

Availability  Supported by all drivers.

Parameters    handle specifies a valid workstation handle.
              first and last each point to a WORD which will be filled in
              with the first and last character in the font respectively.
              dist points to an array of 5 WORDs which indicate
              the distances between the baseline and the point indicated
              as follows:



              width specifies the width of the largest cell in the font in
              pixels not including effects.
              effects points to an array of 3 WORDs which contain
              information relating to the offsets of the font when printed
              with the current effects.



              effects[0] specifies the number of X pixels
                         of the left slant.
              effects[1] specifies the number of X pixels
                         of the right slant.
              effects[2] specifies the extra number of X pixels to
                         add to compensate for the special effects.

Binding       contrl[0] = 131;
              contrl[1] = contrl[3] = 0;
              contrl[6] = handle;

              vdi();

              *first = intout[0];
              *last = intout[1];
              *width = ptsout[0];
              dist[0] = ptsout[1];
              dist[1] = ptsout[3];
              dist[2] = ptsout[5];
              dist[3] = ptsout[7];
              effects[0] = ptsout[2];
              effects[1] = ptsout[4];
              effects[2] = ptsout[6];

Caveats       SpeedoGDOS is not capable of generating values for dist[1]
              or dist[2] so dist[1] is set to equal dist[0] and dist[2] is
              set to equal dist[3].
