TransformationResize issue with very "long" image

Hi,

I have an issue with the TransformationResize calculation of the image high. With an image with

w:954, h: 6228 and an setting_display_size of : 3600

It calculates an h: 146

The generated Image by the thumbnail-function is not "nice" and not usable for OCR.

I do not understand the details of the function TransformationResize.execute_on function, but I looks like development is not finished (e.g. fit is always false).

I am happy to support if there is a short "requirements" description for this function, that I am not going into a wrong direction.

For OCR I would prefer to use the original Image-size or make the size configurable.

As an quick workaround I added "size=None" :

class OCRBackendBase(object):
    def process_document_page(self, document_page):
            logger.info(
                'Processing page: %d of document version: %s',
                document_page.page_number, document_page.document_version
            )

            image = document_page.get_image(size=None)

All inputs and suggestions welcome.

thx & br Matthias
