Detailed Description

H3DImageLoaderNode is a virtual base class for classes that read an image file format such as PNG or JPEG and construct an Image class with the data from the file.

Each subclass must define the loadImage () function. It is used by e.g. the ImageTexture node.

Member Function Documentation

virtual string H3D::H3DImageLoaderNode::defaultXMLContainerField (   )  [inline, virtual]

Returns the default xml containerField attribute value. For this node it is "imageLoader". Reimplemented from H3D::Node.

H3DImageLoaderNode * H3DImageLoaderNode::getSupportedFileReader (  const string &  url  )  [static]

class that can handle that file type. If no such class is registered NULL is returns.

virtual Image* H3D::H3DImageLoaderNode::loadImage (  const string &  url  )  [pure virtual]

Pure virtual function to load an Image from a url. Returns: An Image * with the image data loaded from the url. Implemented in H3D::RawImageLoader.

static void H3D::H3DImageLoaderNode::registerFileReader (  const string &  name, CreateNodeFunc  create, SupportsFileFunc  supports )  [inline, static]

Register a file reader that can then be returned by getSupportedFileReader(). Parameters: name  The name of the class create  A function for creating an instance of that class. supports  A function to determine if the class supports a given file type.
