pixel invert plugin

I have a VFD screen. VFD's have a habit of degrading pixels and was wondering if anyone has made a plugin to invert the pixels that are lit.

If there are no plugins that do this, I am willing to create one if someone would point me in the direction of the source code for the bugnum.dll plugin.

CVS yielded no results.

I don't think this is possible because the characters are 5x8 on a 6x9 matrix so

would turn out something like:

BTW if you hunt around you will find the sources for bignum in amongst the lcdsmartie sources on sourceforge.

Yea thanks for that. I tried it as well by inverting all the custom chars into the LCD screen via a micro and had the same effect.

Like you mentioned it is the spaces in between that kills the effect.

It would only work if you could invert the backlight as well
