exif_thumbnail -- Retrieve the embedded thumbnail of a TIFF or JPEG image


string exif_thumbnail ( string filename [, int &width [, int &height [, int &imagetype]]] )

exif_thumbnail() reads the embedded thumbnail of a TIFF or JPEG image.

If you want to deliver thumbnails through this function, you should send the mimetype information using the header() function.

It is possible that exif_thumbnail() cannot create an image but can determine its size. In this case, the return value is FALSE but width and height are set.

Seznam parametrů
