C++ (Cpp) FrameBufferFontDBFind Examples

Example #1

int txtbox(char *fntname,float sze,int num,char *txt,float *box,void *data) {
  struct FrameBufferFontDB *fontdb;
  struct FrameBufferFont *fnt;
  int tbox[3];

  fontdb=(struct FrameBufferFontDB *)data;
  if (fontdb==NULL) return -1;
  fnt=FrameBufferFontDBFind(fontdb,fntname,sze);
 
  FrameBufferTextBox(fnt,num,txt,tbox);
  
  box[0]=1.1*tbox[0];
  box[1]=1.1*tbox[1];
  box[2]=1.1*tbox[2];
  return 0;
