  there is a number of ways to do this
  1 create a variable in fr with no value, when you use it in the report and it is
  encountered by the report engine the external ongetvaLUE EVENT OF FR IS FIRED and
  you canpass a value into it from delphi.
  see the programmers manual on working with variables.
  2 create a custom function to use in fr, see the developers manual
  on how to create custom functions
  3 create a library of customfunctions and compile them and install them into fr
  so they can be seen from the function list

  Thank you.
  I already solved that, I wrote a function to get R, G, B values from TColor. Calculate the color from from begincolor and endcolor of gradient.
  
  create a library of custom functions - I didn't think about it, thank you, next time I'll do so.
