I've written a program to process a bunch of png files that are generated by a seperate process. The capture mostly works, however there are times when the process dies and is restarting which leaves a corrupted image. I have no way to detect when the process dies or which file it dies one (there are ~3000 png files). Is there a good wa...

I am supposed to write a program that gets some PNG images from the user, does some simple edits like rotation and saves them inside a JAR file so that it can use the images as resources. The problem is when I open, say an 80kb image and then save it with C#, I get an image with the same quality but for 130kb space. And because it has to...
