Quick Start

After installing the panel it will appear in the Window > Extensions (Legacy) Photoshop menu.

Note that Lasso Draw isn’t a usual Photoshop tool like a Brush or a Move Tool, but rather a mode for all the selection tools (and the Line Tool!): an easy way to automate the process of acting on a selection (and also since it’s not a native tool there will always be a bit of lag). The way the panel works is it waits for you to create a selection and then acts on it, meaning that Lasso Draw should be turned On or Off. This could be as easy as you want: the state of the tool could be modified directly from the panel by selecting Off, Add or Clear modes or using a keyboard shortcut to toggle between Off and Add.

Additionally, holding Ctrl (Windows) or Cmd (Mac) or E before finishing the selection will cut the shape instead of adding to it, acting as Clear mode. holding Shift or I before finishing the selection will pick a color from the first point of selection. In this example I cut a part of the crown while holding Ctrl and then sample a brighter yellow color with Shift:

Holding both the Ctrl/Cmd and Shift key in the same time when finishing the selection will make the panel to not act on the selection. This is useful, for example, for transforming a selected area without the need to turn the panel off.

If you have a selection already when turning on the panel, it will be acted upon. If you turn on a panel with a non-selection tool, the Lasso Tool will be selected. The panel could be turned off automatically when a non-selection tool is selected or when it’s turned off (see options).

The panel includes several fill modes: from the most basic “fill selection with the foreground color” to more advanced modes like “fill with noise”, “play action” or something absolutely out of the world: “transform”.

And the Line Tool can be used instead of the selection tool with certain modes. In this example the Line Tool is used with the Gradient mode:

The panel also has some basic API to be used in scripts.
