Preview imagesPreview images — Class describing preview images (or thumbnails) that are part of the metadata. |
GExiv2PreviewImage is an accessor to the preview images contained in the image's metadata. This could be anything from a thumbnail to a full-sized camera development of a RAW image.
The GExiv2PreviewImage is obtained by calling gexiv2_metadata_get_preview_image()
with an instance of GExiv2PreviewProperties that are describing the image
to be fetched.
