如果位图大于2500x2500,则不会旋转,否则会旋转 返回值始终为true。是否有任何设置可以设置增加大小限制?
pts[0].x := dynamicBMP.height;
pts[0].y := 0;
pts[1].x := dynamicBMP.height;
pts[1].y := dynamicBMP.width;
pts[2].x := 0;
pts[2].y := 0;
y := plgblt(TempBmp.canvas.Handle,
pts,
dynamicBMP.canvas.Handle,
0,
0,
dynamicBMP.width,
dynamicBMP.height,
0,
0,
0);
if y = false then
raise Exception.Create('Plgblt failed');
