ClrDraw
RecallPic 0 //replace 0 with the pic to store in the list
95*64->Dim(LPIC //replace LPIC with the name of the list to store the pic to
For(A,0,94
For(B,0,63
If Pxl-Test(B,A
1->LPIC(95B+(A+1 //replace LPIC with the name of the list to store the pic to
End
End
You can of course optimise and change it, but this should give you the general idea.
Back to pic:
ClrDraw
For(X,1,95*64
If LPIC(X
Then
Int(X/95->B
X+1-95Ans
Pxl-On(B,Ans
End
End
StorePic 0

| Is there any way you could do something like 1->LStr1 so that the user could enter the name of the list they wanted before it starts storing the pic? |

| That is impossible in basic. Also, I think storing Pics to Strings takes much less space. |

Depends heavily in the compression routines that are used, still, I doubt any screen with more than half it's pixels turned on will be smaller in a string or list. |

Numbers in strings always take less space than in lists, unless each number is more than 9 digits.

My compression program works based on changes in color, not on what the color is. A completely black picture would take up the same amount of bytes as a completely white picture - 16 bytes. |

Yeah, but he means half and half or so. Like an actual picture, not just an empty (or dark screen)

| I compressed one 47 by 47 image out of your avatar (the one of the spider) and got 560 bytes (not exact since I did half and multiplied by two). If you put it into a regular pic file, it would only increase by about 50 bytes, since the rest would be left blank. |

Quote: Numbers in strings always take less space than in lists, unless each number is more than 9 digits. Jup, but Strings can become bigger than pics if there is too much data stored to them. So if anybody stores every single pixel of a pic to a string as x and y coordinates, for example, it would definetly become much bigger than a pic.
Quote: My compression program works based on changes in color, not on what the color is. Good for you, but who want's to store the pic of a completely white or black screen? Note I said it depends heavily on the compression routine used.

You have to use the little L. Press [2nd][STAT][>][^].

A little bug here, lists can't have more than 999 elements. You attempt to make one that is 6080. Oops.
And there's another, you can't Pxl-Text(>62,>94).

| When you create a list, you either say {0 -> Lname or go into the editor in the Stat menu, type in the name of the new list and press enter. |

Creating lists:
{1,2,3,4->LNAME
1->LNAME(1
1->Dim(LNAME
Replace NAME with any combination of up to 4 characters.

Up to 5 characters.
You can also do
{1,2,3,4 -> NAME
and it will assume NAME is a list and store to LNAME
