[Xpert]About XDrawLine

[martin_ding2001]

Hi, All     I got a strange problem about XDrawLine's speed. In Sun's Ultra 10 machine(U10), I use XDrawLine function to draw lines continuously, it works OK. But when I use the code in HP(changed nothing), and the XDrawline shows  more slow, even you can see how the line is drawed. The Sun and HP machine all support multi Visual, but XDrawline in them show different speed. However, if just use single visual(for example, use xmanager login HP, it may just supoort 24 bit true color), XDrawline works well enough, speed is as fast as we need.     Is there anyone who can me the reason and way to solve it?
