LAVA 1.0 Content Posted June 13, 2008 Report Share Posted June 13, 2008 Some one knows about an activeX or dotNET control that can display images at a higher frame rate then the picture control. Currently I use the picture control to display 2d array of RGB value (32bits) as fast as I can, but I use Flatten Pixmap.vi and it takes 30ms to process my 640x480 image and it take a lot of CPU time. Is there other way to do this? Thanks Dany Quote Link to comment
AndyDm Posted June 13, 2008 Report Share Posted June 13, 2008 You can use IMAQ Draw from IMAQ Vision. As far as I know IMAQ Vision license is not required for this function. Andrey. Quote Link to comment

But this will require a bit more programming work with WinAPI. Andrey. Quote Link to comment

LAVA 1.0 Content Posted June 13, 2008 Author Report Share Posted June 13, 2008 It work great. I pass from 20fps 60% of CPU to 30fps 10% of CPU it's much better that way. Thank you all for the reply, and thank you Norm for the hack Dany Quote Link to comment
