plotting Ascii in bitmap [message #52327]

Hi,

I need to plot colored numbers (and letters) on a bitmap and then save the
result. It's not necessary to view the overlay bitmap in IDL.
so:
x = read_tiff('bitmap.tif')
overlay=x ;maybe be make an RGB here..
plottext('kjdhkj',positionrow,positioncol)
plottext('323',positionrow,positioncol)
write_tiff, x, 'overlay.tif'

Does anyone know how the plottext() function should look like? I did it once
by:
tvsxcl,x
plot, stuff
oplot, stuff...
tvrd, overlay
but this isn't very practical if x is 5000x5000 bitmap...

Thanks,

Gert
