If you have photoshop, do the following to get the scanline effect:
New Document (Ctrl+N)
Height 3 pixels
Zoom in to the maximum(1600%)
Choose the Pencil Tool(right click on the Brush Tool Icon)
Make it 1 pixel large, black color.
Click it one time on the middle of the picture, and it should look like this:
Go to Edit>Define Pattern and that's it, scanline made.
Now on how to use it::
Open a sig/wall/whatever you're doing that requires the scanline, and do the following:
In the layers window click the icon on the bottom as higlighted on the picture??
Choose "Pattern" from the menu, and that's it. If nothing appears, jsut move the newly made layer on the top and it should be there, a 1 pixel scanline in perfect order over the whole picture.
"Ok. Quick question, what's a render and why do you use it?"
A render, as known on the forum boards is actually a high-quality picture of a character, car, acter, just about anything, and it is already cut and made transparent so you don't have to bother doing it yourself. On the other hand, a render is actually a term used in 3d programs, and fractal programs, etc. Renders are those cool 3d pictures and fractals you see all over the net, constructions, models, it's all a render because the program has to render
it to make it a jpeg.
Those are the crummy scan lines. If you pattern that, it would be 1 line black, then 2 lines clear...see what im saying? Its better to just make a 1 px wide by 2 px high.
