Open an image as described in section 1.2 "Open image and Apply Random Style". Switch from Projects to the Style Browser on the right. Select a style (e.g. Building Blocks/Simple Styles/Random Painter). There are three methods for applying the selected style to the image.

• Press “Enter” on the selected style.
• Double-click the selected style.
• Drag and drop the selected style directly onto the layer. The layer will be highlighted.

The style's name is displayed automatically in the Layer Browser. For complex styles that require a few seconds for application, you will see the processing occur in the Compositing viewport and in the Rendering Preview Progress Bar. You may cancel the processing at any time if you do not like the resulting effect, or if you want to try another style instead, just by clicking the Abort button, or using the Esc key.

Select the layer in the Layer Browser, and switch to the “Properties + Preview” pane. If the style has exported properties, adjust the property that you want to modify by dragging the slider to the desired value. The resulting image will be rendered in real time in the Preview window and then in the Compositing viewport.
