B4J Question Iterate over files to resize images

[Giu]

Hi,

Today I had to create a little project, and I did in python because I was in a hurry for deliver, but because I want to dive into B4J since a lot of time ago, I want to replicate this little project in B4J

I have a folder with thousands of images. I need to take each image, resize a couple of times, do a web request with them (POST and PATCH) and move this files to another files writing a log file.
About web requests I think is OkHTTPUtils2 what I have to use, and about OS file moving and so on, I have to dive into the forum, but what I searched in the forum and I didn't found, was about image manipulation. What should I use for this?

Regards.

The answer to this:

What should I use for this?

Yes, here it is,

although tbh I usually download that spreadsheet to the local PC and use regular spreadsheet software = way faster and simpler

about image manipulation. What should I use for this?

I just published [Source code] ImageScaler for resizing images without UI component 3 weeks ago. You can tweak the source code as you like. If you need more powerful or advanced image resizing methods like batch processing, async or multithread , you can check the Java source code of ImgScalr .
