Detailed Description

A widget for showing a scaled version of an image (QPixmap).

The scale is just a suggestion, given to Qt by calls to sizeHint(), which returns the image size multiplied by the scale. The actual rendered size is the largest that fits the image into the current widget size without changing the aspect ratio. It is always rendered in the center.
