ImageIO API for GUI Support
The Need
When building GUI applications based on ITK, it is common to use the ImageFileReader and ImageFileWriter classes, that through the ImageIO Factories are capable of supporting a large number of image file formats.
There are in fact, so many file formats supported, that it is challenging to list them all in the File Dialog of a GUI at the application level.
Current Support
Currently the ImageIO classes support the GUI interfaces by providing the following API
ArrayOfExtensionsType GetSupportedWriteExtensions() const ArrayOfExtensionsType GetSupportedReadExtensions() const void AddSupportedWriteExtension( const char * extension ) void AddSupportedReadExtension( const char * extension )
Proposed API
Enumeration of Extensions
- Suggested API for the ImageIO classes
- unsigned int GetNumberOfExtensions() const;
- std::string GetNthExtension(unsigned int) const
