How to Display Image in C++
Hi!
I'm trying to write a function in C++ to show an image on the screen.
How could I do that?
I have already created a .JPG image but I was unable to use it inside a C++ software.
Please, explain me.
Thanks in advance!

Which OS are you using?
Which compiler / IDE are you using?
Do you want to do all the maths yourself - shouldn't take more than a year or two.

Or do you want to use a library that just gives you the pixels?

Same goes for the display side.
Do you want to write each pixel yourself, or do you want to use a library to do some (or all) of the work for you?
Many GUI toolkits provide the means to display an image from a file, with very little code on your part.
