[Gambas-user] Suddenly no more color printing

[Rolf-Werner Eilert]

One of my programs should be able to print PDFs with colors (background 
colors in table cells).

It did so last year and it did so during winter. But when I use it now, 
it suddenly makes grayshades instead of the colors.

As far as I remember, I have not changed anything in these code parts 
(printing part), and I guess it's the same Gambas version (3.12.2 on 
Ubuntu Mate 18.04.2). There are outstanding updates, and I haven't 
updated the system for couple of months, but alas...

Where would you look first? I need these colored tables...

Thanks for your ideas!

Rolf
