Convert PUB to JPG PNG TIFF Image Java

Microsoft Publisher Files are used for printing or publishing information. You can convert PUB) to JPG, PNG, or TIFF images programmatically using Java. In this article, you will learn how to convert the PUB file to different image formats:

PUB to Image Conversion – Java APIs Installation

Aspose.PUB for Java API supports working with PUB files. You can render the PUB files to PDF and then utilize Aspose.PDF for Java API to convert the output PDF file to image formats like JPG, PNG, TIFF, etc. You can download the JAR files for Aspose.PUB for Java and Aspose.PDF for Java API or specify the following configurations to download the APIs from the Maven repository:

Convert PUB to JPG Image Programmatically using Java

You can convert a Microsoft Publisher (PUB) file to JPG image with the following steps:

  1. Load input PUB file.
  2. Convert PUB to PDF file with convertToPdf method.
  3. Get page dimensions from the PDF document.
  4. Specify the Resolution and dimensions of the output image.
  5. Save output JPG image using JpegDevice.

The code below explains how to convert PUB to JPG image using Java:

// Load input PUB file
IPubParser parser = PubFactory.createParser("Test.pub");
Document doc = parser.parse();
// Convert PUB to PDF file
PubFactory.createPdfConverter().convertToPdf(doc, "Test.pdf");
// Load the PDF file
Document document = new Document("Test.pdf");
facades.PdfFileInfo info = new facades.PdfFileInfo(document);
for (Page page : document.getPages())
{
// Get page dimensions from the PDF document
int width = (int) info.getPageWidth(page.getNumber());
int height = (int) (info.getPageHeight(page.getNumber()));
// Set resolution for the output image
devices.Resolution resolution = new devices.Resolution(300);
// Create JPEG device with specified Width and Height
devices.JpegDevice jpegDevice = new devices.JpegDevice(width, height , resolution);
// Convert PUB to JPG image
jpegDevice.process(page, "Page" + page.getNumber() + ".jpg");
}

Convert PUB to PNG Image Programmatically with Java

You can convert a PUB file to PNG format image with the steps below:

  1. Load input PUB file with createParser() method.
  2. Convert PUB to PDF file.
  3. Specify width and height of output image.
  4. Finally, convert PUB to PNG image.

The following code shows how to convert PUB to PNG image with Java:

// Load input PUB file
IPubParser parser = PubFactory.createParser("Test.pub");
Document doc = parser.parse();
// Convert PUB to PDF file
PubFactory.createPdfConverter().convertToPdf(doc, "Test.pdf");
Document document = new Document("Test.pdf");
facades.PdfFileInfo info = new facades.PdfFileInfo(document);
for (Page page : document.getPages())
{
// Get page dimensions from the PDF document
int width = (int) info.getPageWidth(page.getNumber());
int height = (int) (info.getPageHeight(page.getNumber()));
// Create PNG device with specified Width and Height
devices.PngDevice pngDevice = new devices.PngDevice(width, height);
// Convert PUB to PNG image
pngDevice.process(page, "Page" + page.getNumber() + ".png");
}

PUB to TIFF Conversion Programmatically in Java

You can convert PUB file to a TIFF image with the steps listed below:

  1. Firstly, load the input Publisher (PUB) file.
  2. Convert PUB to PDF file using convertToPdf() method.
  3. Specify properties for TIFF image using TiffSettings class.
  4. Finally, convert PUB to TIFF image with TiffDevice instance.

The following code demonstrates how to convert PUB to TIFF image programmatically using Java:

// Load input PUB file
IPubParser parser = PubFactory.createParser("Test.pub");
Document doc = parser.parse();
// Convert PUB to PDF file
PubFactory.createPdfConverter().convertToPdf(doc, "Test.pdf");
Document document = new Document("Test.pdf");
facades.PdfFileInfo info = new facades.PdfFileInfo(document);
// Get page dimensions from the PDF document
int width = (int) info.getPageWidth((int)(1));
int height = (int) info.getPageHeight((int)(1));
devices.Resolution resolution = new devices.Resolution(300);
devices.TiffSettings settings = new devices.TiffSettings();
settings.setCompression(devices.CompressionType.None);
settings.setDepth(devices.ColorDepth.Default);
// Create TIFF device with specified Width and Height
devices.TiffDevice tiffDevice = new devices.TiffDevice(width, height , resolution, settings);
// Convert PUB to TIFF image
tiffDevice.process(document, "Output.tiff");
