This tutorial shows how to create a Java application that uses the
RasterCodecs class to save each page of a multipage image into a separate image file.

Get familiar with the basic steps of creating a project by reviewing the Add References and Set a License tutorial, before working on the Split a Multipage Image File Into Separate Files - Java tutorial.
Start with a copy of the project created in the Add References and Set a License tutorial. If that project is unavailable, follow the steps in that tutorial to create it.
The references needed depend upon the purpose of the project. References can be added by local
.jar files located at
For this project, the following references are needed:
This tutorial uses LEADTOOLS Codec library support. For a complete list of which JAR files are required for your application, refer to Files to be Included with your Java Application
The License unlocks the features needed for the project. It must be set before any toolkit function is called. For details including tutorials for different platforms, refer to Setting a Runtime License.
There are two types of runtime licenses:
Adding LEADTOOLS references and setting a license are covered in more detail in the Add References and Set a License tutorial.
With the project created, the references added, and the license set, coding can begin.
Main.java class in the Project Explorer. Add the following statements to the
import block at the top.
// import block at the top
Add a new method called
SplitFile(). Call this new method in the
run() method after the
SetLicense(); method call. Add the below code to the
SplitFile() method to split a multipage file into separate
PNG files. For this tutorial we used this multipage TIFF file.
String multipageFile = "C:\\LEADTOOLS22\\Resources\\Images\\merged.tif";
RasterCodecs codecs = new RasterCodecs();
int totalPages = codecs.getTotalPages(multipageFile);
for (int page = 1; page <= totalPages; page++)
File tempFile = new File(multipageFile);
String fileWithoutExt = tempFile.getName();
fileWithoutExt = fileWithoutExt.substring(0, fileWithoutExt.lastIndexOf("."));
String outputFile = "C:\\LEADTOOLS22\\Resources\\Images\\" + fileWithoutExt + "_page" + page + ".png";
RasterImage image = codecs.load(multipageFile, page);
codecs.save(image, outputFile, RasterImageFormat.PNG, 0);
Run the project by pressing Ctrl + F11, or by selecting Run -> Run.
If the steps were followed correctly, the application runs and creates new
PNG files. Each page of the sample TIFF file should be created as a
PNG image file, with the page number appended to the name.
This tutorial showed how to add the necessary references to load all the pages of a
TIFF image file and split them into separate
