How do I copy a block of memory (image) in LV array

[pdx]

Hi,
I need to read and copy image data from memory to LV array. I use HWaccess VI (read a byte) but the loop time is too long, is there any solution with specific DLL which realise a total copy in LV array ?

Thanks
Francois.

My system: P4/Win2000/LV 6.0/IMACVISION

If you just want to copy an IMAQ Image into a 2D array, I recommend using the IMAQ ImageToArray.vi.

If you have NI Vision installed, then you could also use the IMAQ GetImagePixelPtr.vi to return the memory location of the first pixel and reference the rest from there.
