+# Name:        wx.lib.embeddedimage
+# Purpose:     Defines a class used for embedding PNG images in Python
+#              code. The primary method of using this module is via
+#              the code generator in wx.tools.img2py.

+    PyEmbeddedImage is primarily intended to be used by code generated
+    by img2py as a means of embedding image data in a python module so
+    the image can be used at runtime without needing to access the
+    image from an image file.  This makes distributing icons and such
+    that an application uses simpler since tools like py2exe will
+    automatically bundle modules that are imported, and the
+    application doesn't have to worry about how to locate the image
+    files on the user's filesystem.
+
+    The class can also be used for image data that may be acquired
+    from some other source at runtime, such as over the network or
+    from a database.  In this case pass False for isBase64 (unless the
+    data actually is base64 encoded.)  Any image type that
+    wx.ImageFromStream can handle should be okay.
