[Gambas-user] PictureBox.Picture.Image[x, y] output interpretation

[kevinfishburne]

When retrieving the value of a pixel at x,y from the picture in a picturebox
control it outputs a single value. How does this value represent the pixel's
value, and can it be easily converted to an RGB value?

This is something that's going to need to be done 4,294,967,296 times, so is
there a quicker way to reference pixel RGB values from a large image? The
image being read will be of a varying format, 8192x8192 pixels and
grayscale. The high number of "reads" is because it's being used as a
modifier by an algorithm that is generating a 65536x65536 grayscale image.
