Detailed Description

Image viewer widget for KStars.

Author:

Thomas Kabelmann

Version:

1.0

This image-viewer automatically resizes the picture. The output works with kio-slaves and not directly with the QImage save-routines because normally the image-files are in GIF-format and QT does not save these files. For other formats, like PNG, this is not so important because they can directly saved by QImage.

The download-slave works asynchron so the parent-widget can be used at this time. The save-slave works synchronously, but this is not important because the files are at this time local saved and this works not so long.
