Hi all,
I=B4m writting because I have a colours trouble. I have to use the
BLACK colour in a graphic mode screen, I think you have to rewrite the
colours routine, and made a BLACK color and a TRANSPARENT colour by diferent
constants.
Thanks,
Red Knight

This gave me a lot of grief a while back. Apparently, it's a problem with
how the PC does colors, not with Euphoria.
The solution is simple - use polygon() to clear the screen to the color that
you want. So if you want to clear the screen to a background color of WHITE,
draw a filled white polygon the size of the screen. It's the solution that I
use.

There is also another method which I used, where you save a piece of the
background the same size of the image to display, display the image, and then
fill in the black area around the image with pixels from the saved image. You
can create a data sequence with the relative points around the picture and
use a repeating algorhythm to fill in the black area with saved pixel data.
