writeDirectory - Class: Tiff

Create new IFD and make it current IFD

Syntax

Description

tiffobj.writeDirectory() create a new image file directory (IFD) and makes it the current IFD. Tiff object methods operate on the current IFD. If you are creating a TIFF file that only contains one image, you do not need to use this method. With single-image TIFF files, just close the Tiff object to write data to the file.

Examples

Open a TIFF file for modification and create a new IFD in the file. writeDirectory makes the newly created IFD the current IFD. Replace the name myfile.tif with the name of a TIFF file on your MATLAB path.

t = Tiff('myfile.tif', 'r+');
dnum = t.currentDirectory();
t.writeDirectory();
dnum = t.currentDirectory();

References

This method corresponds to the TIFFWriteDirectory function in the LibTIFF C API. To use this method, you must be familiar with the TIFF specification and technical notes. View this documentation at LibTIFF - TIFF Library and Utilities.
