## Implement

You can implement a new type of image loader plugin.
implement LoadBitmapFromImage and LoadImageHeader in the loader-dummy.cpp file.

 bool LoadImageHeader( const Dali::ImageLoader::Input& input, unsigned int& width, unsigned int& height )
 {
  bool success = false;
  /* Loads the header of a image file and fills in the width and height appropriately. */

  return success;
 }

 bool LoadBitmapFromImage( const Dali::ImageLoader::Input& input, Dali::Devel::PixelBuffer& bitmap )
 {
   bool success = false;
   /* Loads the bitmap from an image file.  This function checks the header first */

   return success;
 }

And register your new image loader in tizen-image-loader.cpp
 1) add type of new file formats
   enum FileFormats
  {
    // Unknown file format
    FORMAT_UNKNOWN = -1,

    // formats that use magic bytes
    FORMAT_DUMMY = 0,
    FORMAT_TOTAL_COUNT
  };

 2) add function of new image loader
  const Dali::ImageLoader::BitmapLoader BITMAP_LOADER_LOOKUP_TABLE[FORMAT_TOTAL_COUNT] =
  {
    { 0x0,                0x0,                LoadBitmapFromImage,  LoadImageHeader,  Dali::Integration::Bitmap::BITMAP_2D_PACKED_PIXELS },
  };

 3) add file extensions and formats
   const FormatExtension FORMAT_EXTENSIONS[] =
  {
    { ".dummy",  FORMAT_DUMMY  }
  };

## Build
To use the new Image Loader plugin, You must change the use_image_loader value to 1.
 packaging/dali-extension.spec
 # Use Image Loader Plugin
 %define use_image_loader 1

 When you build the dali-extension, dali-extension-image-loader-plugin.armv7l.rpm file is created.
