Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

Hi All

Using a MM+ with a colour LCD I would like to use the Text command
without it using a background colour.
I have a BMP for the background and would like to overlay the text on the bmp
without the text setting its own background colour

Is this possible ?

Regards
Jman

Not without some significant changes to the firmware. The way it works is that a display region is created the size of the character, the software then clocks through the character's bitmap and either sends the foreground or background colour without having to do any further pixel positioning

To do what you want the firmware would need to send each foreground pixel individually and re-position over each background pixel. This would be much slower.

It could be done in a CFunction but it would be a pretty complex one and not fast
