Hello,

I would like to scale a JPEG image proportional, e. g. from 250 x 120 to 100 x 100.
But I'm not sure which method is the best one and how can I use it.
Could anybody give me an example?

Thanks. :)

Hi

You need to use IEImage.Resample():

You can pass -1 as the width or height to ensure it remains proportional, e.g.

Image.Resample( 100, -1, IEResampleFilter.FastLinear );
