GrayDraw (Grammer)
« on: November 03, 2011, 11:12:59 pm »
GrayDraw is currently a very simple grayscale drawing program. You just input the name of the file to open and if it doesn't exist, it is created, otherwise, it is used. Note that this version does not check if the var is archived or not and it won't check if it is the right size (in case the var already existed).

You can do some simple drawing in 4-level gray that works best on models with 15MHz.

I might end up adding the ability to draw other shapes such as lines, rectangles, and circles, in the future.
I should also add in error checking XD

In any event, it looks better on a real calc than it does in the screenie, but I have this one anyway :D

EDIT: Uploaded correct version XD

Does it create greyscale by alternating on and off for all the grey pixels?  It might look better if you choose to dither them such that every other grey pixel is on half the time, and the other pixels are on the other half time.

XD Runer just said to steal it from Axe O.O
The only problem is that I am using Grammer code to display the grayscale (not pure assembly). Though I could add actual grayscale support in the future...

Keoni, you realize that doesn't answer his question at all, that just makes him feel bad?

:) Thanks buttsfredkin and aeTIos :)
And I do have a command to draw a checkerboard pattern (both checkerboards) so what do I have to do with them? Do I perform AND logic with that and the buffer I want to display?

I at first didnt too. Most members are boys, and I also assume that with a new member.
