c# - Paint Draw Image from another Thread? -

i read can increase drawing speed/time drawing paint event, , can draw unscaled.

so try on panel.

the problem though, image recieved in thread gui, , don´t know how give paint event.

i don´t want invoke , stuff (as incredibly slow, @ least when have used it).

the code look, this.

protected override void panel1_paint(object sender, painteventargs e, image u) {          e.graphics.drawimageunscaled(u, point.empty);  } 

though there tried using override add add image in field, ald wanted make static, call thread. sadly t didn´t work.

but well, tried.

private void panel1_paint(object sender, painteventargs e) {       //   e.graphics.drawimageunscaled(u, point.empty);  } 

there "working" one, except can´t image it.

i tried making image variable, save image in variable, , paint it. paint never see image in it, can´t access image, guess cause it´s written thread.

//initialize private image im;  ////////  thread  im = image.fromstream(....); ////////////7           void panel1_paint(object sender, painteventargs e)         {                  if(im !=null)                 e.graphics.drawimageunscaled(im, point.empty);                   } 

this how tried, , failed.
