Project Description

What I have doed myself is (see attachment):

1, I load a 32-bit-depth PNG file (1 pixel 4 byte) into a byte array.

2, I manipulate the byte array thus changing the pixels.

so far everything works... but what I can't seem to do is:

3, Take this manipulated byte array and save it back into a new PNG file.

So in short, your task is to write me a code snippet, a function, that

1, takes a byte array (containing the pixel data of a loaded 32 bit depth PNG file)

2, takes a string containing the Directory bath + the file name of the new png file.

3, creates this 32-bit-depth PNG file in the specified directory.

The code should be as simple and clean as possible. Nothing too fancy... I am a newbie programmer and would love to easily understand it.

Thank you.
