How to change brightness and contrast in an enhanced meta file

[Dielmann]

Hi
I need to know how to change brightness and contrast in an enhanced meta file.
This modification must be done between the GetEnhMetaFile and PlayEnhMetaFile functions.
Any hints or code pieces if available are welcome.

ICM is a way to change colors.

Another way is enumerating all EMF records, and change all the pen, brush, bitmap colors within it. You can enumerating them and play them in the same loop.
