54.2Exntension to Function's Capability

This module extends the capability of function image() and instance method image#write() so that they can read/write TIFF files.

When function image() is provided with a stream that satisfies the following conditions, it would recognize the stream as a TIFF file.

  • The identifier of the stream ends with a suffix ".tif" or ".tiff".

When instance method image#write() is provided with a stream that satisfies the following condition, it would write image data in TIFF format.

  • The identifier of the stream ends with a suffix ".tif" or ".tiff".

54.3Extension to image Class
