I used SetTextColor(1,0,0) to change to RED text. It work fine. Now, on the same document, I want to switch back to BLACK. SetTextColor(1,1,1) doesn't work. It gives me white (invisible) color instead.

I tried something counter intuitive to me: SetTextColor(0,0,0). It is how you choose BLACK. Problem resolved.

The 3 values are RGB values between 0 and 1. Other libraries use a range of 0 and 255.
0,0,0 = Black (0% red, 0% green, 0% blue) 1,1,1 = White (100% red, 100% green, 100% blue) 1,0,0 = Red (100% red, 0% green, 0% blue) Andrew. |
