[Insight-users] Multiply an Image by Constant

[Miller, James V (Research)]

Sergio, 

You can use the ShiftScaleImageFilter to add a constant and scale the
intensity of every pixel in an image.

Subject: [Insight-users] Multiply an Image by Constant


Hi all,

I think is a little stupid question, but
could anyone tell me how can multiply a given image by a constant??

I am using filters like AddImageFilter, or MultiplyImageFilter.. for 
doing things like:
Image3 = Image1 + Image2
Image4 = Image1 * Image2

But I did not found a filter or function to do:
Image2 = Image1 * K

I thought about iterate over pixels and multiply each pixel by K.
But I don't know if there is a better solution....

Thanks for your possible answers..

Sergio.
