Getting form pixels

I need to get the pixel colors of a form in a non-sequential, non-
linear, almost random way. In other words, xy in one particular
sampling might be 122,34 followed by another sampling in which xy
might be 45,76 for example.
    Would it be faster to get the screen pixels than to use
form1.canvas.pixels[formx,formy] or is there another way? I realize
that I may be stuck with form1.canvas.pixels[formx,formy] but I'm
asking just on the possibility that there might be another way. The
form will display constantly changing imagery.

Well, I must be able to get the form pixel colors so I'll use the
canvas method but I'll be able to make up some speed lost because of
that by using a dynamic array to store the xy and other info that the
canvas method uses instead of reading that info from a text file. I'll
be using something like the code shown below. Merry Christmas!

  Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i type 
companions = array[1..7] of string;  grouper = array of
companions; begin item :=
grouper.create; setlength(item,arraysize);  //Various stuff here end;
