XnView Software

First of all Thx a lot (again) for this fantastic piece of work

Alright, I have some questions about some functions of the SDK...

The tolerance parameter of gflAutoCrop will be used how?
Is it some kind of percentage.
How will it work.

And what does gflAverage exactly do?
Parameters (filter_size) work how?

It's the maximum difference between pixels!

It's a the filter size, so 3, 5, 7, 9, 11, 13

It's a filter like blur, an average between all pixels!

MaierMan, before asking you could try and check out the effects & filters in XnView. FAIK, often the GFL functions are named like the effects and filters.

How can I determine the background with a certain color tolerance before auto-crop?Also when I write 200 it crops,but when I make the tolerance 500, it does not make anything. When tolerance is more,should it crop if it crops for a lower value?
