I´m testing “Tiff Editor” program for our customer.
I don´t understand, why first TIF picture offer only two colours (Black and White) and second picture offer more colours. Customer needs use object “Line” with red colour.
Same problem with Text tools.
The number of colors depends on the picture itself.
For black and white, only two colors are offered (black and white).
You can convert black and white to color.
In this case, you can use any color.
