Images To PDF
Developers can use IronPDF to combine multiple images into a single PDF document.
PdfDocument.fromImage method accepts a list of
Path objects, each of which reference a valid path to an image stored on a local file system. This gives the developer a lot of freedom in specificity. He can build this list to include groups of images spanning multiple directories, to include images matching specific naming or typing criteria, etc. In the case where the images are sourced from the same directory (as is the case in the above code example), the developer can simply utilize a
DirectoryStream among other
java.nio.file classes to quickly build up a list of all the images contained in the directory.
PdfDocument.fromImage will render each image referenced in the list on a separate page in the PDF document.
If the images need to be placed in separate PDF documents (not combined into one), then developers can do either of the following:
- Iteratively call
PdfDocument.fromImageusing lists containing only one Path object (e.g.
- Combine all images into one PDF document as shown in the above code example, and then copy each page into new PDF documents with the
