Hyperion - editing custom button shapers

Editing

Hyperion is a visual editor for creating and editing files that define custom button shapers.

It has two panes - control panel on the left and editor panel on the right.

Use "Load image" button to load the source image in the editor panel. This image should have the shape / outline that you want to trace and serve as the basis for your custom button shaper.

Use "Load contour" button to load an existing .shaper file into the editor. Alternatively, you can start editing a new contour, as Hyperion starts you off with one major and one minor point.

Major and minor points serve to anchor the shape outline and create curved segments. Use radio buttons in the control panel to switch between add, delete and edit modes.

In edit mode, click and drag a major or minor point to change its location. In add mode, click to add a major point. In delete mode, click a major point to delete it and its minor point.

When you're done with editing, click "Save contour" to save the serialized representation of the contour.

Runtime usage

The extras pack comes with three helper classes that you can use to load and display custom button shaper outlines:

  • ShaperRepository has methods for reading and writing serialized .shaper files.
  • CanonicalPath is returned by .read and accepted by .write methods in the repository. After reading a serialized .shaper file, use CanonicalPath.getPath to get a Java2D GeneralPath that matches the size and insets of the relevant control.
  • BasePolygonShaper is the base abstract class that brings it all together, implementing the core SubstanceButtonShaper interface.

See XYZShaper classes in org.pushingpixels.substance.extras.api.shaperpack package for examples of how extra button shapers are implemented with these helper classes.
