Antialiasing and Alpha Blending o.O


Recommended Posts

You can go here for an explanation for Antialiasing and Alpha Blending:

C:\Program Files\Paint.NET\Help\en\Tools.html

Antialiasing helps you draw things with better and more smoother edges.

Alpha Blending controls the transparency of the image, I'm guessing.

Don' just guess :D

Anti-Aliasing is the smoothing of lines, which would normally have "stairs", because they are not going in horizontal or vertical direction.

I think this picture from the german wikipedia explains it quite well:

Alpha Blending is an option of Paint .NET which, if activated allows half (or at least not completely) transparent drawing over the picture without removing the existing colors, just modifying the alpha value.

Bah, I can't explain that one very well :wink:

Why not just quote the help file :)http://www.eecs.wsu.edu/paint.net/doc/2 ... Tools.html

When you choose a color, you may specify an Alpha component. This part of the color determines how to blend it in with the pixels that are already on the layer when you draw. An alpha value of 0 means completely transparent, whereas an alpha value of 255 means completely opaque. Antialiasing also uses alpha blending for the edges of shapes and brushes.

However, there are times when you do not want to blend a color in to the existing pixels, and instead want to replace the color on the canvas with exactly the color and alpha values you have specified.

It's not the easiest one to understand, but not having it would be an enormous loss of functionality, trust me :) I use it a lot, especially when doing per-pixel editing.

rick brewster has a gigantumonguous brain that is definitly hung like a horse. He knows almost everything about everything so his post I would regard as bible law. Mr brewster thanks very much for allowing me to use paint.net it has been a honour matched only by the honour of being able to use paint.net (which can be found at http://paintdotnet.12.forumer.com/viewt ... highlight="

But how do you use the alpha blending to fade one image into another? Say I have upload a new image and then I put a white rectangle along the border so that it blends. Isn't this what I would use alpha blending for? I guess I don't know how to do it. Does each of the images have to be on a seperate layer to work? Any guidance would be helpful. Thanks.
