This is the time to resize the image if you wish. When you choose the Změna velikosti / Resize command (Nový obraz / New image menu), The Panorama Factory runs the modal Změna velikosti obrazu / Resize image dialog box.  You enter the new size of the image with this dialog box.

The Panorama Factory scales the image using low-pass filtering so that the resulting image is free of sampling artifacts.

If you want to change the image size later, select the resized image and use the Zdroje / Show source command (Obraz / Image menu) to redisplay the Změna velikosti obrazu / Resize image dialog box.

You can also resize a group of images by selecting a group of thumbnails before choosing the Změna velikosti / Resize command.  All the images will resize to the same width or height (or both), depending upon which numbers you enter into the dialog box.

On the other hand, if you like the size the way it is, just advance to the next step without resizing the image.
