Old Paper - Put an old paper texture on the screen

[Dav]

Here's a little SUB I made a while back and never shared.  Thought it may be useful.  It paints an old paper texture at given screen coordinates and you can specify the color of the paper.  It uses a very small grey paper image which is layered with a given color using the LINE statement.  The texture looks okay when filling both small and large screen areas.  I've found it handy for several kinds of programs.

This method is kind of outdated now that QB64PE can embed image files, and also has BASE64 built-in.  But for those who still like to stick things in code, here you go.

Hello! Nice program!

I have always wondered how an image can be drawn using those characters. Can you please enlighten me?

[SpriggsySpriggs]

@Delsus, the image is being stored in a deflated string that he then inflates and loads into memory. It's just the raw binary of the image but compressed.

Dang I was hoping to see what Rho used for the Wiki, the realistic looking rough paper. That might be done with an image also? Don't think its drawing that paper.

[Pete]

No, no, no! That's a utility, not a program!!!  

My artistic talent is strictly linear in nature, so I could never come up with stuff like this in a million years. +2
