Controls

The SDK offers controls for all available tools. The default toolset consists of tools for Transform, Filters, Adjustments, Text, Stickers, Frames, Brush, Focus and Magic.

All available tools are implemented as PhotoEditToolController subclasses and get presented in a stacked layout, starting from the PhotoEditViewController as root, which is embedded in a ToolbarController for hierarchy and toolbar management. Each tool controller can be configured using its corresponding ToolControllerOptions subclass as described in the configuration and customization sections.

A single tool controller consists of four main views:

1. workspaceView - The view showing the image thats currently being edited and any changes, e.g. brush strokes or stickers, that are applied to it
2. overlays - A set of buttons that are overlaid on the workspaceView and offer functionality like ‘Redo’, ‘Undo’ or ‘Bring to front’
3. accessoryView - The default place for controls, that belong to the current tool
4. toolbar - The bottom toolbar, managed by the ToolbarController. Displays the current tool and allows apply/cancel actions.
