Create new IFD and make it current IFD

Syntax

writeDirectory(t)

Description

writeDirectory(t) creates a new image file directory (IFD) and makes it the current IFD.

Examples

Add IFD to TIFF File

Create a new TIFF file and add two new IFDs to the file.

Create a Tiff object for a new file.

t = Tiff('myfile.tif','w');

Add a new IFD to the file and display the current directory number. You can use this new IFD to add image data and tags to the TIFF file.

writeDirectory(t);
currentDirectory(t)

ans =

Add another IFD to the file and display the current directory number. You can use this IFD to save an additional image to the same TIFF file.

writeDirectory(t);
currentDirectory(t)

ans = 
2

Close the Tiff object.

close(t);

Input Arguments
