[Qt-interest] How to render text on Image with different color???

[trinathpujari]

Hi All,

          I have text drawn on QImage. Now i want to change back ground 
color as black and text as some other color(selected).I am checking each 
pixel color and updating the pixel color. But text is becoming distorted.
     Alternative to this i did invert pixel at that time text is coming 
properly but Back ground is different(Not black which i wanted).
          Please help me to resolve this.

Thanks in Advance,
Trinath
