A library is a storage place for a collection of tools or media. In Corel Painter, default libraries are available for the following resources: brushes, brush sizes, captured dabs, papers, color sets, gradients, looks, nozzles, textures, patterns, selections, scripts, images, weaves, and flow maps. The default libraries contain a vast array of resources that are ready for you to use. In addition, you can create your own libraries to better organize resources, or to store customized resources.
