Macromedia Flash Guide - The Ink Bottle

Just as the Paint tool is used to change the fill of objects, you can use the Ink Bottle icon to modify the outline of object. The tool recognizes and works only on lines whether they form an outline of an object or are standalone lines created with the Line Tool or Pencil Tool.

In addition to changing the color of lines, you can also modify their thickness and style.

Flash ink bottle modifiers

Note: You can change the properties (color, style and thickness) of several lines (and outlines) by selecting all of them and clicking on the selection with the ink bottle modifier.

The Ink Bottle tool acts ONLY on lines, so if both ouline and fill are selected, only the outline will be changed.
