Vectorizer

This script makes a vector shape layer based on the composite image contents.

1. Open any image.
2. By default, the script selects on the picture the darker areas. To use the lighter areas, just invert the image color (fig. 1) by pressing [Ctrl+I] keys.
3. Run the "Vectorizer" script.
4. In the dialog box that opens, play with the "Threshold" slider to achieve the best black-to-white ratio (fig. 2). Now the darker areas of your image are selected (fig. 3).
5. There appears the "Refine Edge" dialog. If necessary, smooth the jagged edges to round the outlines of the created path (fig. 3).

   

6. Now that selection is converted to a vector path, the script asks you, if you want to create from it a shape layer (fig. 4).
7. If you click "No", the outline stays in the document just as Work Path and you can find it in the "Paths" dialog.
8. If you click "Yes", a new shape layer appears in the Layers palette. To change its color call the Color Picker by double-clicking on the "Color Fill" layer thumbnail (fig. 5).
