It seems that you are going to have to modify the image data of the picture file. There are some examples of this on the community website. Depending on the bit depth of the image the following example may not work. You should be able to modify this example to take in a jpeg with (Read JPEG File.vi).

Hi,

You can extract Hue plane of the color image, modify the extracted plane and replace it back to original image.

Thanks for the reply.

I think with IMAQfill I can get this job done...

Glad to hear you figured it out

I also was able to write up an example which modify the amounts of Red, Green, and Blue. This example extracts the red, green, and blue hue planes from a 32 bit RGB image. I have imported an IMAQ shipping example image from file.I put it on the community website.
