Scale(double, double) does nothing

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Add jar to project (eclipse)
2. Run code:

Thumbnails.of(file.getInputStream())
                    .scale(100, 100)
                    .outputFormat(newFile.getExtension())
                    .toFile(newFile.getAbsolutePath());

I want to recieve the scaled thumbnail image, but this piece of code does 
nothing without throwing any exception. What is interesting that if I change it 
to size (with same parameters):
Thumbnails.of(file.getInputStream())
                    .size(100, 100)
                    .outputFormat(newFile.getExtension())
                    .toFile(newFile.getAbsolutePath());

I am using 0.4.2 version on Win7x64, JDK version 6.

Forgot to add - interesting that if I change it to size (with same parameters) 
the code works fine

Sorry for the late response.

The `scale` and `size` methods achieve different things.

* The `scale` method is to be given a scaling factor, such as 0.5, to reduce 
the image to 50% of the original image.

* The `size` method is given the actual size that the thumbnail should be, in 
pixels.

Therefore, depending on what you're trying to achieve, the choice between using 
`size` or `scale` will differ.

Since you've mentioned in Comment 1 that using `size` works fine, I'm going to 
assume that the `size` method is able to achieve what is being sought after.

That said, using `scale(100, 100)` resulting in "nothing" does seem odd, so I'm 
have to try it out and see if I can reproduce the problem.

Thank you for the feedback.

This issue has not been updated in more than half a year, so I will assume that
