X xwings Unregistered / Unconfirmed GUEST, unregistred user! 2001-09-25 #24 呵呵,好啊,各位少等几天. 到时一定把源码贴出来. 大家觉得好的话不要忘了给分就可以了.
D dark_eagle Unregistered / Unconfirmed GUEST, unregistred user! 2001-09-25 #25 没问题,只要是用directx抓图实时监视远程屏幕的,你要多少分尽管出声!
火 火凤凰 Unregistered / Unconfirmed GUEST, unregistred user! 2001-09-25 #28 如果不要求写硬盘的话,我觉得我一秒能抓15祯左右(800*600*16M色), to xwings 用directx的. 抓屏。怎么抓?能给例子吗?

C caowei Unregistered / Unconfirmed GUEST, unregistred user! 2001-10-12 #30 测试结果: Piii-800, 128M, 1024*768: bitblt用时间250ms...... 还能快吗?
C caowei Unregistered / Unconfirmed GUEST, unregistred user! 2001-10-12 #34 不会吧? 12MS????? 我的程序代码: time1 := gettickcount; //建立screen bitmap ScreenBmp := TBitmap.Create; ScreenBmp.Width := screen.Width; ScreenBmp.Height := screen.Height; ScreenBmp.PixelFormat := pf24Bit; dc := GetWindowDC(0); try ScreenCanvas.Handle := dc; BitBlt(ScreenBmp.Canvas.Handle, 0,0,screen.Width,screen.Height, dc, 0,0,SRCCOPY); finally ReleaseDC(0, DC); end; ShowMessage(inttostr(gettickcount-time1)); 800*600: 差不多150MS左右!!!!!!!

老 老赵 Unregistered / Unconfirmed GUEST, unregistred user! 2001-10-12 #37 我指的是 dc := GetWindowDC(0); BitBlt(ScreenBmp.Canvas.Handle, 0,0,screen.Width,screen.Height, dc, 0,0,SRCCOPY); 这二句,不包括其他语句的执行时间. 另外,您的代码我运行 72ms 奇怪,啥也没动! ShowMessage(inttostr(gettickcount-time1)); 换为caption:=(inttostr(gettickcount-time1)); 60ms.

C caowei Unregistered / Unconfirmed GUEST, unregistred user! 2001-10-13 #38 那12MS是指哪部分呢? 我也感觉很奇怪啊.....是我的机器有问题? 我是在98,2000下都测试了. 要不,就是显示卡的问题. 我用的是SIS 6326, 8M显存.
