Android Question How to select a small part of JPG file and save it into antoher JPG?

[pablo77]

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,

Pablo

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
https://www.b4x.com/android/forum/pages/results/?query=crop+image&page=1&prefix=0

good luck!
