Except for PdfRenderer, which is under a different license due to its use of (A)GPL components, all of the plugins in this edition are released under the Freedom license (for v3) or the Apache license for v4.

Everything here can be found in the free download.

Logging, MvcRoutingShim, and PdfRenderer are separate DLLs (due to extra dependencies), but all the rest are found in ImageResizer.dll in the ImageResizer.Plugins.Basic namespace.
