First of all it is important to be aware that saving styles is not allowed in the Simple Layout.

_____Save a New Style

Create a style as explained previously in 2.3 Chained Styles and in 2.4 Layered StylesTo save the created style, choose “Save Current Style” from the Styles menu or click the Save Style floppy icon in the Layer browser.

Whether you choose to save from the menu or the Save Style floppy disk icon, the “Save Style” dialog box appears. In the Publishing pane, enter a name for your style in the Name field and select the Category where the styles should be saved. Your own styles can be saved only in the User category, but you can create as many child-categories as you want inside the User folder as shown in tutorial 2.0 The Style Browser
You can also add a short description to the style or you can leave it blank. Next add a thumbnail to your style.  Either take the picture you are working with and using the scroll bar under the magnifying glass icon to zoom in or out of it to personalize the thumbnail, or choose from the reference images in the window to the right of your picture.  

In the Properties pane, select those properties you want to make modifiable after the saving. These properties will be seen in the Properties+Preview pane when applying the style to an image. You can set the range values – minimum and maximum – to each property. These range values serve as the recommended values when applying the style to other images. Any non-exported property will keep their current values, which will define the specifi look of the style. Click OK to save. 

Your style will appear in the User/chosen-category. We saved our style called Painting with Outlines in the main My Styles category.

You can test your style by applying it to your image. The style’s name is displayed on the Default Layer just like the built-in styles.

As you can see, the previously saved style has a few exported properties. You can update your own style anytime by clicking the double-arrow button in the Layer browser (on the left of the Save Style button). The Save Style dialog box appears again. Switch from the Publishing pane to the Properties pane and check all the properties you want to export. 

Click OK when you’re done. Your style is now updated. You can test your style again by applying it to your image. The style’s name is displayed on the Default Layer just like the built-in styles and its exported properties can now be modified in the Properties+Preview pane to best fit your images.


_____How to create a *.stylez package
“Stylez” is the name of a zipped file containing more than one style. To create style packages, simply save, and publish your styles.  Then zip them into a single archive (without directories). Rename the resulting file with a *.stylez extension.


It is recommended that you use 1000x1000px images to create styles that you intend to publish and share. This is the optimal image size that allows the correct property scaling. If you work with 4000x4000px size images, the properties (exported or not) will not be rescaled correcty on the end user's smaller images, while scaling from 1000x1000px to a 2000x2000px will surely give best results.

Choose the thumbnail that best shows the applied style’s effect on an image. You can zoom into the thumbnail to personalize it or to show more details, such as the textures, of your style. The reference images are 400 x 400 pixels, and the thumbnails are 200 x 200 pixels.

If you have several instances of the same filter in your style, their properties would have the same names if they were exported unchanged. The "Save Style" dialog will not allow this, so you must rename these exported properties. This is a good time to give them descriptive names, based on the role of the filter in the style.
