Adobe PDF Library - It is based on the technology of Adobe Acrobat software.JasperReport - It is an open source Java reporting tool which generates a report in PDF documents.iText - It is an open source Java library which supports the development and conversion of PDF documents.Libraries to create and manipulate PDF document: ![]() Each PDF file has fixed, secure and multidimensional layout including text, fonts, graphics, audio, video, animation and hyperlinks. The main goal of PDF document is to enable the users to exchange and view electronic/digital documents easily and reliably. It is developed and specified by AdobeĀ® Systems as a universally compatible file format based on the PostScript format. ![]() It is independent of the environment in which it was created or the environment in which it is viewed or printed. It is a file format which is used to display a printed document in digital form. Our PDFBox Tutorial includes all topics of PDFBox Tutorial such as Introduction, Features, Create First PDF Document, Adding Page, Load Existing Document, Adding Text, Adding Multiple Lines, Removing Page, Reading Text, Extracting Phone Number, Working With Metadata, Working with Fonts, Working with Attachments, Inserting Image, Extracting Image, Get Location and size of Image, Adding Rectangles, Splitting PDF Document, Merging PDF Document, Validation, Encrypting PDF Document, etc. We can also use it to digitally sign, print and validate files against the PDF/A-1b standard. It allows the creation of new PDF documents, manipulation of existing documents, bookmarking PDF and the ability to extract content from PDF documents. It supports the development and conversion of PDF Documents. PDFBox is an open-source library which is written in Java. Our PDFBox Tutorial is designed for beginners and professionals both. Import .PDFBox Tutorial provides basic and advanced concepts of PDFBox Library. Import .FileCacheRandomAccessOutputStream Most of the following code is from the OP with some changes due to package name change and more ImageParam control settings. Here the sample pdf I am going to use is princeCatalogue. Some new features were added to "icafe" recently such as better quantization and ordered dither algorithms which is used in the following example code. It's been a while since the question was asked and I finally find time and a wonderful ordered dither matrix which allows me to give some details on how "icafe" can be used to get similar or better results than calling external ghostscript executable. I found that the produced tif from ghostscript strongly differs in quality from the tiff produced by icafe (the group 4 tiff from ghostscript looks greyscale-like) Throw new MyException(ErrorMessages.GHOSTSTSCRIPT_ERROR) Private static void savePdfAsTiff(PDDocument pdf) throws IOException ", exitVal) Import cafe.io.FileCacheRandomAccessOutputStream The sample pdf which I use in the example is located here: import Has anybody an idea what the issue is here? The sample code works for me for 288 dpi but strangely NOT for 300 dpi, the exported tiff remains just white. ![]() I'm trying to convert PDFs as represented by the .PDDocument class and the icafe library ( ) to a multipage tiff with group 4 compression and 300 dpi.
