Image Compare

infonoteinfonote Member Posts: 233
Hi,

How can I compare 2 images with the same filename, to see if there have been any changes to the image since the last time it was checked?
Is there a function in NAV which does this?

Thanks in advance
Peter

    You can create a checksum for each file and compare these. If they are the same, then the files are identical.

    Search the forum or the Internet for terms as MD5, SHA1, CRC.

    i don't think NAV can compare images, because NAV is a business solution software. so why NAV compare images, what is that important? Which conditions required images comparing?

    Probably, a binary compare will suffice to do the job for you. If so just read the two pictures, one byte (CHAR) at a time, and compare. Luc's suggestion might perform better, if you can find and implement a working solution.
