You could just put a label on top of it.

I would usually go for either having a fully custom drawn component,
where I manage all paint, like here:

http://wiki.lazarus.freepascal.org/Developing_with_Graphics#Create_a_custom_control_which_draws_itself

Or, if using a TImage, try to put a label on top of it. I've never
needed to draw to the canvas of a TImage, because I usually use
TCustomControl descendents for complex drawing, but there are
instructions here:

http://wiki.lazarus.freepascal.org/Developing_with_Graphics#Draw_to_a_TImage

Then cache the TBitmap in the creation of your form and free on it's
destruction.
