Re: A83: Ways of Drawing to the Screen?
Ok, it probably does, if you say so... I need to clarify more then. How do I
NOT make it write to the display so it does not look bad while its being
drawn...? I dont want it to the display, Just the buffer, and then copy the
buffer once Im done drawing everything... In your Periodic Table program, I
see the lines as theyre being drawn, and how do you make it so that they would
just pop up, and the whole table completely drawn? I know "_ILine" doesnt do
this on its own, so any ideas? Would "_Cline" be any different, or is that
just on how its points are inputted, or are there any flags to help correct
this problem that Im having of "_Iline" drawing to the display...?
