Package com.idrsolutions.image.pdf

Class PdfEncoder

java.lang.Object

com.idrsolutions.image.JDeliImage

com.idrsolutions.image.pdf.PdfEncoder

All Implemented Interfaces:

com.idrsolutions.image.Encoder

public class PdfEncoder
extends com.idrsolutions.image.JDeliImage
implements com.idrsolutions.image.Encoder

Class generates a PDF from a BufferedImage or Image file
If the image is a multi-page TIFF then this class generates a multi-page PDF file

Example 1 (writing from a BufferedImage):

 File pdfFile = new File("C:\\path\\to\\output\\file.pdf");
 pdfFile.createNewFile();
 PdfEncoder encoder = new PdfEncoder();
 encoder.write(bufferedImage, pdfFile);
 

Example 2 (writing from a File):

 File pdfFile = new File("C:\\path\\to\\output\\file.pdf");
 pdfFile.createNewFile();
 PdfEncoder encoder = new PdfEncoder();
 encoder.write(new File("C:\\path\\to\\input\\image.PNG"), pdfFile); //can be BMP, JPEG, TIFF or any supported Image

write

public void write(BufferedImage image,
 File pdfFile)
           throws IOException

Write a buffered image into a PDF file.

Parameters:

image - buffered image to be converted

pdfFile - output PDF file to write to

Throws:

IOException - if an error occurs in writing image

write

public void write(File imageFile,
 File pdfFile)
           throws Exception

Writes an image file into a PDF file.

If the file is a multi-page TIFF then this method writes a PDF with the same number of pages as the TIFF file contains.

Parameters:

imageFile - input image file to be converted

pdfFile - output PDF file to write to

Throws:

IOException - if an error occurs in writing image
