Val tpsDocument = File( "Assets/tpsReport.pdf")ĭocumentEditor.importDocument( 0,, FileDataProvider(tpsDocument))Īgain we added the two documents, and for the final operation, we instructed the Document Editor to remove the first page. Val projectDocument = File( "Assets/projectPlan.pdf")ĭocumentEditor.importDocument( 0,, FileDataProvider(projectDocument)) With the two documents combined into one, we now have a front page that doesn’t reflect the data it holds.įile projectDocument = new File( "Assets/projectPlan.pdf") ĭocumentEditor.importDocument( 0,, new FileDataProvider(projectDocument)) įile tpsDocument = new File( "Assets/tpsReport.pdf") ĭocumentEditor.importDocument( 0,, new FileDataProvider(tpsDocument)) So now, let’s look into the many features of the Document Editor. We completed our task and merged two documents together. Opening and appending PDFs can be a memory-intensive process, so if you’re importing large documents, keep this in mind. One factor to be aware of is the size of the PDFs in memory. We can keep repeating these steps to merge as many documents as we desire. #Java pdf merge codeIn the code example above, we take a simple file path, but it’s also possible to pass a custom data provider that extends DataProvider to provide data from any source required, such as memory, network data, or even a cryptographic solution. Then we instruct the Document Editor where to find the document to import. With just a few lines of code and the PSPDFKit Document Editor, we managed to merge our documents into one.Įach document is added by calling the importDocument method, with 0 denoting index 0 and instructing the editor to place the pages before the given index (this is necessary for the first document, as there are no other indices to reference yet). val outputFile = File.createTempFile( "dogCatPair", ".pdf")ĭocumentEditor.saveDocument(FileDataProvider(outputFile)) Val catDocument = File( "Assets/cat.pdf")ĭocumentEditor.importDocument( 0,, FileDataProvider(catDocument)) val dogDocument = File( "Assets/dog.pdf")ĭocumentEditor.importDocument( 0,, FileDataProvider(dogDocument)) 0 denotes the page index of where to insert the document. 0 denotes the page index of where to insert the document.ĭocumentEditor documentEditor = new DocumentEditor() įile dogDocument = new File( "Assets/dog.pdf") ĭocumentEditor.importDocument( 0,, new FileDataProvider(dogDocument)) įile catDocument = new File( "Assets/cat.pdf") ĭocumentEditor.importDocument( 0,, new FileDataProvider(catDocument)) įile outputFile = File.createTempFile( "dogCatPair", ".pdf") ĭocumentEditor.saveDocument( new FileDataProvider(outputFile)) // Get two documents and merge them together. Get two documents and merge them together. We’ll merge these two pages together to create a PDF document with one page. In our hypothetical situation, we’ll have two PDF documents, each consisting of one page. If you’re looking for an expressive language with the possibility of native JavaScript and Java interoperability, it could be worth checking out the Kotlin guides. The great thing is that it works in most places Java does, so if you want the benefits of a new and interesting language but with the environment of Java, Kotlin is the way to go. Because it’s been around for such a long time and is still popular, we can be sure it won’t go away anytime soon.Ĭompared to Java, Kotlin is the new kid on the block. #Java pdf merge androidToday, it’s most likely known for being used with Android or on backend server work. Java has a long history and is used in many different environments. #Java pdf merge how toBut how do you do that? In today’s post, I’ll show how to merge multiple PDF documents into a single PDF using Java and Kotlin, thereby solving the redistribution problem! Java and Kotlin And in some cases, it can be useful to collate these documents to redistribute them. Many companies have reams of documents about customers, employees, inventory, etc.
