Description

Dear Concerned,

 

Dear Concerned,

 

We need to convert images into PDF. We have many format of image type like tiff with any compression (G3, G4, LZW or Jpeg compression), JPEG, BMP, PNG. Images can be single strip or multistrip/multitiles.

 

We have converted these images into buffered image and add it to pdf page but for all type of image only compression set is /flatdecode. I need to set different compression for different image format.

 

Kindly suggest how to set the compression while inserting image in creation mode of PDF

 

Code:

{

PDDocument document = new PDDocument();

//generated buffered image BufferedImage bim;

                PDPage page = new PDPage(new PDRectangle((int) bim.getWidth(), (int)bim.getHeight()));

               document.addPage(page);

               //Creating PDImageXObject object 

               PDImageXObject imgObj = null;

         try

{                                 imgObj = LosslessFactory.createFromImage(document, bim);                                 }

catch (IOException e)

{                                                 // TODO Auto-generated catch block                                                 e.printStackTrace();                                 }

        //PDPageContentStream contentStream = new PDPageContentStream(document, page, AppendMode.OVERWRITE,true,true);

         PDPageContentStream contentStream = new PDPageContentStream(document, page);

               contentStream.drawImage(imgObj, 0, 0);

               contentStream.close();

               //fileForInput.close();

 

               document.save(outputFile + ".pdf");

               document.close();

}
