## The Parameter Tab

On the right side you can choose a tab titled 'Parameter'. There you can preview a part of the output image with the desired zoom. ( You find it in the same tabbed view as this help, click onto 'Parameter' above ). This view shows only a part of the result. It is only for giving you an impression of the zoom and for testing enlarging parameters.

You can drag around the contents with the mouse. When you click somewhere in the little 'Thumbnail Preview' on the left, the region around this point is displayed magnified in the right view.

By clicking onto the Preview button, you can see what the enlarger does with the contents of the magnified view.

In the Parameter Tab you can adjust some enlargement parameters:

- Sharpness: higher values lead to sharper edges, might look artificial if too sharp
- Flatness: higher values produce more 'painted' looking results with less gradients
- PreSharpen: applies simple sharpening to the source before enlarging
- Dithering: add a slightly analogue looking grain-structure to the result
- DeNoise: remove some noise and artifacts from the source
- FractNoise: just a gimmick: get some irregularity into your result; contours and colors are modified by plasma fractal noise.

You can switch between predefined settings in the combo box.
To change a setting, first check 'Allow Changes'.
You can create a new set cloning the current one by clicking 'New'. For a new settings name type something into the combo box, don't forget to hit the ''Return' key at the end to adopt the changed name.
