replace image pixel values using replace array subset - too slow!

[sau]

Hi

I would like to replace specific pixels in my image such that I get a specific pattern.  I'm using replace array subset but since my image from the ccd is in fact 2048 x 1536, the vi runs very slowly.  Is there any image functions that I could use instead?

The pattern that I want is every 2nd row and col (bayer pattern) and the user will get to choose how large of an area to replace.

Thanks,

sau

Hi sau -

I recommend building a mask (with IMAQ Mask) for the image and applying it to get the desired effect. You can build it from user input with the IMAQ ROIToMask function.
