如何在PixelFormat=pf1bit的Bitmap中正常显示文字?

Question

源码如下:TImage显示正常,为淡淡的红色字.   Image2.Picture.Bitmap.PixelFormat:=pf1bit;
   Image2.Canvas.Brush.Style:=bsClear;
  
   Image2.Canvas.Font.Name:='黑体';
   Image2.Canvas.Font.Color:=clRed;
   Image2.Canvas.Font.Height:=32;
   Image2.Canvas.TextOut(0,0,'程序');TBitmap中无法显示,始终为黑色,为何?
   var
     pic:TBitmap;   pic:=TBitmap.Create;
   pic.PixelFormat:=pf1bit;
   pic.Width:=100;
   pic.Height:=100;
   pic.Canvas.Brush.Style:=bsClear;   pic.Canvas.Font.Name:='黑体';
   pic.Canvas.Font.Color:=clRed;
   pic.Canvas.Font.Height:=32;
   pic.Canvas.TextOut(0,0,'程序');
   pic.Free;只有将pic.PixelFormat:=pf24bit,才能正常显示.请问高手,如何解决?

pf1bit什么意思?用1位表示颜色,那自然只能有两种颜色~~~解决办法也简单,自己修改位图调试板颜色
