Get Color Index (256 color)

[gamecreator]

I've been looking through the Image Class Reference and it seems like SFML can't do this but I just want to confirm.  I'm drawing a tile map out in a graphics program where each pixel represents a tile.  I was hoping to read the image into SFML and have it tell me which color index each pixel is (from 0 to 255) so I can draw the proper tile based on that.  However, while I can get the RGBA values, I can't find where I could get the pixel color index.  Is this possible with SFML?  If so, how can I do this?  I have no problem with writing a converter or something but just checking here first.  Thanks for any help.

SFML doesn't provide access to the color palette. You could just use the pixel position on the image though.

To be a little clearer, after SFML loads an image, all you get is an array of RGBA values (and a size), so any extra information such as the original palette is definitely lost.

Thank you both.
