Changing the brightness and contrast of an image displayed in a picture control

[zou]

My Image Toolbox VIs can load and manipulate images, Compatible with LabVIEW picture control. And only costs half the price of ImgX.

Terry, Could you send an example VI using ImageX. I need to adjust brightness/contrast of an picture, but I'm unfamiliar with ActiveX controls.

Thanks

I know this is an old post, but someone else might find this useful...this is a very easy way to adjust contrast on either greyscale 8-bit image array or individual RGB arrays:

When implementing in Labview, do the calculations on each element as a double precision before converting to U8 data type and passing to the picture control.
