C++ (Cpp) vgFlush Examples

Example #1

//Display functions
void display(float interval)
{
  int i;
  const VGfloat *style;
  VGfloat clearColor[] = {1,1,1,1};
  
  if (animate) {
    ang += interval * 360 * 0.1f;
    if (ang > 360) ang -= 360;
  }
  
  vgSetfv(VG_CLEAR_COLOR, 4, clearColor);
  vgClear(0,0,testWidth(),testHeight());
  
  vgSeti(VG_MATRIX_MODE, VG_MATRIX_PATH_USER_TO_SURFACE);
  vgLoadIdentity();
  vgTranslate(testWidth()/2 + tx,testHeight()/2 + ty);
  vgScale(sx, sy);
  vgRotate(ang);
  
  for (i=0; i<pathCount; ++i) {
    
    style = styleArrays[i];
    vgSetParameterfv(tigerStroke, VG_PAINT_COLOR, 4, &style[0]);
    vgSetParameterfv(tigerFill, VG_PAINT_COLOR, 4, &style[4]);
    vgSetf(VG_STROKE_LINE_WIDTH, style[8]);

  }
  vgFlush();
}
