USING THE CODE

Convert All Pages of a PDF File to TIFF

The following steps show how to convert all pages of a PDF file to TIFF.

l  Initialize a PdfDocument object.

l  Load a PDF sample document using PdfDocument.loadFromFile() method.

l  Save all pages of the document to a TIFF file using PdfDocument.saveToTiff(String tiffFilename) method.

import com.spire.compression.TiffCompressionTypes;
import com.spire.pdf.PdfDocument;

public class PDFToTIFF {
    public static void main(String[] args) {

        //Initialize a PdfDocument object
        PdfDocument pdf = new PdfDocument();

        //Load a PDF sample document
        pdf.loadFromFile("sample.pdf");

        //Save all pages of the document to Tiff
        pdf.saveToTiff("output/PDFtoTiff.tiff");
    }
}


Convert Some Specified Pages of a PDF File to TIFF
 The following are steps to convert specified pages of a PDF file to TIFF.
l  Initialize a PdfDocument object.
l  Load a PDF sample document using PdfDocument.loadFromFile() method.
l  Save specified pages of the document to a TIFF file using PdfDocument.saveToTiff(String tiffFilename, int startPage, int endPage, int dpix, int dpiy) method.
import com.spire.pdf.PdfDocument;

public class PDFToTIFF {
    public static void main(String[] args) {
        //Create a PdfDocument instance
        PdfDocument pdf = new PdfDocument();
        //Load a PDF  sample document
        pdf.loadFromFile("sample.pdf");

        //Save specified pages of the document to TIFF and set horizontal and vertical resolution
        pdf.saveToTiff("output/ToTiff2.tiff",0,1,400,600);
    }
}
