Here is Java sample code to export PDF pages to images in various formats: PNG, JPG and TIFF using Qoppa’s PDF library jPDFImages.
When opening the PDF document, the sample below read the document from a local file, the code can be simply changed to read the file from a file input stream instead.
Export PDF to PNG
// open the PDF PDFImages pdfDoc = new PDFImages ("C://test//mydoc.pdf", null); // loop through the pages for (int count = 1; count <= pdfDoc.getPageCount(); ++count) { // export page image at 150 DPI resolution in PNG format pdfDoc.savePageAsPNG(count-1, "C://test//image_page_" + count + ".png", 150); // export page thumbnail at 20 DPI resolution in PNG format pdfDoc.savePageAsPNG(count-1, "C://test//thumbnail_page_" + count + ".png", 20); } |
Export PDF to JPEG
// open the PDF PDFImages pdfDoc = new PDFImages ("C://test//mydoc.pdf", null); // loop through the pages for (int count = 1; count <= pdfDoc.getPageCount(); ++count) { // export page image at 150 DPI resolution in JPEG format pdfDoc.savePageAsJPEG(count-1, "C://test//image_page_" + count + ".jpg", 150, 0.8f); // export page thumbnail at 20 DPI resolution in JPEG format pdfDoc.savePageAsJPEG(count-1, "C://test//thumbnail_page_" + count + ".jpg", 20, 0.8f); } |
Export PDF Pages to TIFF
// open the PDF PDFImages pdfDoc = new PDFImages ("C://test//mydoc.pdf", null); // loop through the pages for (int count = 1; count <= pdfDoc.getPageCount(); ++count) { // export page image at 150 DPI resolution in TIFF format pdfDoc.savePageAsTIFF(count-1, "C://test//image_page_" + count + ".tiff", new TIFFOptions (150, TIFFOptions.TIFF_PACKBITS)); // export page thumbnail at 20 DPI resolution in TIFF format pdfDoc.savePageAsTIFF(count-1, "C://test//thumb_page_" + count + ".tiff", new TIFFOptions (20, TIFFOptions.TIFF_PACKBITS)); } |
Export Whole PDF Document to Multi Page TIFF
It is possible to export all pages in the PDF document to a single TIFF:
PDFImages pdfDoc = new PDFImages ("C://test//mydoc.pdf", null); pdfDoc.saveDocumentAsTIFF("C://test//mydoc.tif", new TIFFOptions (150, TIFFOptions.TIFF_PACKBITS)); |
