TI-BASIC / Re: Draw Pixel-By-Pixel
« on: September 07, 2010, 06:12:07 pm »
Ya. I'm just gonna kinda reiterate everything they said all at once so it hopefully makes more sense for future reference and such.
The first thing you need to do is go to [DRAW] by pressing [2ND] then [PRGM]. Then you need to choose ClrDraw which will erase all the pixels on the screen EXCEPT for equations that are set in [Y=], stat-plots, and the axes. To get rid of the equations and plot points there are many ways to do this. If you want a explanation on how, just ask. But after you get those so they aren't displaying anymore you need to push [2ND] then [ZOOM] to get into the [FORMAT] menu and scroll down and choose AxesOff. Now the graph screen should be completely clear. If you want to be sure you can simply run another ClrDraw. After all that click [GRAPH] and it should pull you up to the empty graphscreen. Click [2ND] then [PRGM] again to bring up the [DRAW] menu and go one menu to the right, to the [POINTS] menu. Go down and click Pt-Change( (or simply hit [3]) and it should take you back to the graphscreen with the cursor being a 3*3 cross with the center flashing. After that you just simply push [ENTER] to turn the pixel on and off. Use this to create the screen. (There are also other drawing functions you can use on the screen to help you, just experiment.) After you have the screen looking how you want to push [2ND] then [PRGM] to get back into the [DRAW] menu and go one menu to the left (or two to the right) and click StorePic. Unless you are using the Text( command (in which case push [CLEAR], [2ND] then [MODE], or [TRACE] or [GRAPH] and then do what I said to get StorePic) it should just appear on the homescreen with a space after the command. You then just put in a number, zero to nine, and push enter and then the graphscreen will be stored to Pic#, "#" being the number you chose. To recall this picture all you do is go back to that screen where you got StorePic but instead of choosing that you choose RecallPic in which it will put it on the homescreen (again, as long as you're not using the Text( command) and you simply type the number of the picture. Those commands are also the ones you would use to do the same inside of a program too, more or less.
Like DJ said, to have another person's calculator recall the correct picture you need to transfer the picture variable (using a transfer cable or by putting all the needed files in a group and then transferring or a number of different methods, point is that you need to have the correct one or it will look weird because the command will recall what ever is stored to those variables that are called, if that makes sense) to the other persons calculator. At which point it is all the work of the program to recall and such. Hopefully this helps more or something. If you have anymore questions just ask

Ah ok. What does a File Archiver do exactly?
Oh well.)
