Detailed Description

The need for this interface is because most of the API's are designed to accept Source-ID as input instead of file-name. Although, the source-id can very well be the file name, the API's do not assume that. Hence whenever an image data is required by image recognition, it relies on this interface to request and get the same from the application.

Member Enumeration Documentation

Enum ThumbnailSizeHint

An input to the thumbnailer expressing the desired size of the thumbnail expected by the image recognition.

Enumerator	Value	Description
ScreenSize	0	In some systems a display-sized thumbnails are stored for quick display of images (since large images take time to decode). The same thumbnails can be reused for image processing instead of attempting to decode the full image
LargeSize		In some cases the image recognition might require the full sized image. In such cases LargeSize is requested.
