Title: Immages in C
Post by: MauryG5 on May 04, 2025, 04:30:27 pm

Sorry guys, I was trying to insert images in jpg format in a code written in C, but I can't figure out how to do it. I've read various information on the net but nothing that is really useful. I was wondering if it is possible to load images using C as a programming language...

Yes, with libjpeg. Works pretty much anywhere.

Hi Classic, thank you for the information, I knew I could count on you. Listen, is there a general procedure or a written code to understand in detail how to write? Always thanks

Something like this would give you a starting point: https://github.com/bitristan/libjpeg-sample/tree/master

Yes perfect thanks, yesterday I looked on github but I hadn't found this part yet. Above all I have to understand how to enter the path each time to make it send the photos I have to display to the screen. It seems that for each new photo I have to write all these lines of code, good work then... ;D

I rewrote all that example code and entered the width and height in the required parameters, those of a photo that I'm trying to run.

Now I managed to get it to start, I made a mistake in the startup file after compiling and then I didn't understand where to put my file. I managed to get the image to start, everything is,
thank you very much Classic!
