Invert Color of Image?

[david.calvin]

Howdy,

 

I have a unique request to see if I can do this inside a jasper report file. Can I invert the colors of an IMAGE? Such as set it as negative colors?

I've seen ways to do it with css, js, and others methods but I do not see how any pair up to fit inside a jasper report.

 

Thank you all

You'll need to pre-negate the image and upload the images on top of each other and with the "Print When Expression" to determine which image to display in the report.
