Resize: optional RIS? #25

Closed zvezdochiot closed 3 years ago

zvezdochiot commented 3 years ago

I'm trying to embed in resizeImage() an optional RIS:

        if (dialog->checkRIS->isChecked())
        {
            QImage imgb = img.scaled(dialog->orig_width, dialog->orig_height, Qt::IgnoreAspectRatio, tfmMode);
        }

How to optimally mirror the original image (data.image) relative to the distorted one (imgb)? Metacode:

<data.image> = <data.image> + multRIS * (<data.image> - <imgb>)
