Integrate with ImageGear for Java

As an alternative to using ImageGear Java PDF to open image formats such as JPEG, TIFF, and others (for example, if you want to convert a TIFF or JPEG image to a PDF), you can use the ImageGear for Java SDK if you have it installed. After the image is opened, you can save it as a PDF document using ImageGear Java PDF.

Integrating the ImageGear for Java and ImageGear Java PDF libraries will enable you to do the following:

Open an image like JPEG, TIFF, etc.
Export the image to a BufferedImage
Create a PDF document with a blank page
Add the image to this PDF page
Save the PDF document

The following is an illustration of how to open an image and convert it to a BufferedImage:

	Copy Code
import com.accusoft.imagegearpdf.; import com.accusoft.imagegear.core.; import com.accusoft.imagegear.formats.; import java.awt.image.BufferedImage; import java.io.; import javax.imageio.ImageIO; class PdfDemo { static { // Load ImageGearJavaPDF library. System.loadLibrary("IgPdf"); // Initialize ImageGear common formats. ImGearCommonFormats.initialize(); } // Load image file to a BufferedImage. public BufferedImage readFileToBufferedImage(String imageFilename) { try { // Open the image file stream. ImGearStream imageStream = ImGearStreams.fileStream(imageFilename, "r"); // Load the first page (in case of the multi-page image) of the image file ImGearPage imagePage = ImGearFileFormats.loadPage(imageStream, 0, null); // Close the image file stream. imageStream.close(); // Convert the image page to a BufferedImage. BufferedImage bufferedImage = ImGearFileFormats.exportToImage(imagePage); return bufferedImage; } catch (Throwable ex) { // Failed to load image file. System.err.println("Exception: " + ex.toString()); return null; } } }

                     return null;
    	      }
       }
}
