# Scaling and Edge Effects

## Content



The **Scalable** property is set to **True** by default. When the **Scalable** property is enabled you can use the **ScaleEffects** property to set the scale factor for the image. You can set the scale effect factor from **0** to **1**. The default value is **0.5**. Given a scaling factor greater than **0.5**, scaling will brighten the image and less than **0.5**, scaling will darken the image.

You can achieve a more brightening or darkening effect using the **ScaleEffects** property more than using the **Offset** property since it preserves the relative contrast of the image better. You will not notice the effects of the **ScaleEffects** property if the **Offset** property is zero.

You can specify the width of the element's edge by setting its **Width** property. When the **Scalable** property is true it is measured in relative units, otherwise it's measured in pixels.
