Hi Ben,
I think you need to clarify this. An image is composed of all kinds of
data, depending on the type of image it is. Things like header
information, version #, color palettes, and other info related to the image
but not actually part of the image itself are included in the binary file
along with the image data itself. You can't just "convert" the image
portion of an image file to hex without knowing something about the
internal layout of the binary data.
I assume what you mean here is if you have an image all of one color you'd
like to get the hex code for that color. So, as I said above, it's not so
easy as just going in and picking a pixel and getting its color. You have
to know something about the image format's image representation.
Otherwise, I suspect that the GD library may have a function to get the
color of a particular pixel whose location (x,y) you specify, though I
don't know the function's name off-hand. You might want to look thru the
GD documentation.
