    Hello everybody,

    Let me introduce myself... My name is Pablo. I'm from Buenos Aires, Argentina.

    I'm new here... Even though I've been reading many posts lately, learning a lot from the valuable information available, this is the first time I write...

    I would like to do something using B4A that actually don't know how to do. Coulnd't find anyone talking about it on the forum (should I look better??)... I'm currently preparing a B4A app that, after taking a picture, can open that file (or just open any other JPG) and let the user select just a portion of the picture and save it (using another file name).

    Could any of you guys point me some material / tutorials I can read? Are there any useful functions I can use? As I said... I basically need to select a part of an original JPG being then able to save it into another JPG file.

    Thanks in advance,

    Hola Pablo, mucho gusto, off the top of my head, i believe you should be able to use a cropping image function to do this, I've seen a few libraries that do this, just do a search for Crop Image and it should return some results.

    Actually, I found some here

    good luck!
