I am making a comic-book annotation program. The user needs to be able to draw arrows on top of a jpeg. Using the line command is useless, since it makes ugly jagged lines. I need a good antialiased line like the one that is drawn in Photoshop.
something like aa_line(20,100,50,150)
should draw aline from x20y100 to x50y150
there's no aa_line functions around, but you can still do it.
Antialias means also the line is blended to it's background, the distance to the line measuring the alpha level for alphablendending.
I also posted this question some time ago.

Unfortunately I did not have the time yet to figure out the algorithm.
Yeah I tried that a while ago... d*mn, I haven't been able to convert a single sample program from pascal or c or c++ that worked :p
So I don't have access to most good techniques because most of them are written in those languages :(
I just have to wait until someone else finds them and converts them to VB :p
