| ok, i know that pxlchk has its 0,0 in the top left corner and the point on has its in the bottom left, is there a little boolean magic to turn this around? i wanna pixl check a dot and if it is 1 then return the coord so it is in the proper context for the pt-on command |

i figured it out once... i dunno how i did it though  sorry! i know i either added or subtracted 47 from 1 number, and 31 with the other... just mess with it and it may work.... what zoom? that also effects it....
Note: my suggestions will only work with the Integer zoom...

If Pxl-Test(Y,X)
Pt-On(X+Xmin,Ymax-Y)
Example:
1->Xmin
1->Ymin
95->Xmax
63->Ymax
If Pxl-Test(Y,X
Pt-On(X+1,63-Y //You can replace 1 with Xmin and 63 with Ymax if you'd want to
You can optimize it of course, for example:
0->Xmin
0->Ymin
94->Xmax
62->Ymax
If Pxl-Test(Y,X
Pt-On(X,62-Y
Of course this only works with an x range of 95 and y range of 63. So if you're using a different windows setting, please say so and I (or somebody else) will think of something that works with your window setting.

| I'm glad that Darth made mention of the fact that it is better to use pxl-on rather than point on when you want to test a pixel. The benifit is just that, the coordinates are the same and don't require extra code that takes up space and speed. |
