Hi guys,

I'm looking to buffer a reference image from my web cam live feed and compare it to the web cam live feed thereafter. I've sent up the buffer chain but when I include pix_diff it produces the following text in the console [pix_diff]: two images do not have equal dimensions (320x240 != 640x480) . How do I get rid of this error message? Am I doing something wrong?

cheers

Well, as the message suggests, the two images don't have the same dimensions. It sounds weird though as both images come from the same camera, right?
Anyway, if you send each image to a [pix_dimen] and set the same dimensions to both [pix_dimen]'s arguments, you'll get rid of this message.
