exif_thumbnail reads the embedded thumbnail of an 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.
The location of the image file. This can either be a path to the file or a stream resource.
The return width of the returned thumbnail.
The returned height of the returned thumbnail.
The returned image type of the returned thumbnail. This is either TIFF or JPEG.
Returns the embedded thumbnail, or false if the image contains no thumbnail.
If the file is used to pass a stream to this function, then the stream must be seekable. Note that the file pointer position is not changed after this function returns.
|The file parameter now supports both local files and stream resources.
