Convert multi-page TIFF to PDF

Aspose.PDF Product Family
1

Dear Support,

I’m looking for an example of how to convert a multi-page TIFF image into a multi-page PDF file using the latest Aspose.PDF version 24.6. Previously, I used version 20.12, and my code in Java was as follows:

import com.aspose.pdf.*;
import com.aspose.pdf.internal.imaging.Image;
import com.aspose.pdf.internal.imaging.fileformats.tiff.TiffFrame;
import com.aspose.pdf.internal.imaging.fileformats.tiff.TiffImage;
import com.aspose.pdf.internal.imaging.imageoptions.BmpOptions;

private void processSingleTiffDocument(Task task, List<String> docNames) throws NnpMigrationDocToolsException {
    if (docNames.size() != 1) {
        LOGGER.error("Document '{}': Expected exactly one document name for TYPE 2 processing, found: {}!", this.documentLogName, docNames.size());
        throw new IllegalArgumentException("Expected exactly one document name for TYPE 2 processing, found: " + docNames.size());
    }

    Document pdfDocument = new Document();
    try {
        Path path = Paths.get(task.getDocDir().toString(), docNames.get(0));
        this.addTiffToPdfDocument(pdfDocument, path);
        this.savePdfDocument(pdfDocument, task, task.getDocDir().toPath());
    } finally {
        pdfDocument.close();
    }
}

private void addTiffToPdfDocument(Document pdfDocument, Path tiffPath) throws NnpMigrationDocToolsException {
    try (TiffImage tiffImage = (TiffImage) Image.load(tiffPath.toString())) {
        for (TiffFrame tiffFrame : tiffImage.getFrames()) {
            try (ByteArrayOutputStream outputStream = new ByteArrayOutputStream()) {
                tiffFrame.save(outputStream, new BmpOptions());
                outputStream.flush();
                try (ByteArrayInputStream inputStream = new ByteArrayInputStream(outputStream.toByteArray())) {
                    Page page = pdfDocument.getPages().add();
                    page.setPageSize(tiffFrame.getWidth(), tiffFrame.getHeight());
                    ImageStamp imageStamp = new ImageStamp(inputStream);
                    page.addStamp(imageStamp);
                }
            }
        }
    } catch (Exception e) {
        LOGGER.error("Document '{}': Error adding TIFF to PDF document! {}", this.documentLogName, e.getMessage());
        throw new MigrationException("Error adding TIFF to PDF document!", e);
    }
}

Unfortunately, this method seems incompatible with the new API. Could you please assist me with this?

Thank you in advance!

Is it possible if you could please share your sample TIFF for our reference in .zip format? We will use it to test the case and prepare a code sample for you to achieve the requirements. Also, please share if you have Aspose.Total license or only Aspose.PDF?

Thank you for the prompt response!

Of course, here is multi-page TIFF sample in .zip format:

Currently, we are exclusively using Aspose.PDF, and our company has a license for version 20.12. I’m testing the latest API (trial version with watermark) to see if it meets our requirements before considering the purchase of a new license :slight_smile:

We tested and found that the code was creating a PDF including only the first page of the input TIF. Therefore, a task as PDFJAVA-44161 has been generated in our issue tracking system to investigate and fix this behavior of the API. We will investigate and definitely come up with a solution to share with you. Please be patient and spare us some time.

We are sorry for the inconvenience.

The issue has been fixed, so multipage tiff is added in pdf with all frames.

Code 1 recommendation: Use aspose internal functionality to determine image width/height instead of using javax.imageio.ImageIO.

Code 2 enhancement: Saving TiffFrames in TiffCcittFax3/4 formats now preserves the 1bpp format (if present) for smaller PDFs and lower memory usage.
Use the following updated snippets:

Code 1:

Document doc = new Document();
// Add a page to the pages collection of the document
Page page = doc.getPages().add();
// Load the source image file into a Stream object
FileInputStream fs = new FileInputStream(dataDir + "file_000001.tif");

// Set margins so the image will fit, etc.
page.getPageInfo().getMargin().setBottom(0);
page.getPageInfo().getMargin().setTop(0);
page.getPageInfo().getMargin().setLeft(0);
page.getPageInfo().getMargin().setRight(0);

Image image1 = new Image();
// Set the image file stream
image1.setImageStream(fs);

// Get the size of the image and set the page size accordingly
Rectangle r = image1.getBitmapSize();
page.getPageInfo().setHeight(r.getHeight());
page.getPageInfo().setWidth(r.getWidth());

// Add the image into the paragraphs collection of the page
page.getParagraphs().add(image1);

// Save the document
doc.save(dataDir + "output_24_7__code1_use_getBitmapSize.pdf");

Code 2:

Document pdfDocument = new Document();
TiffImage tiffImage = (TiffImage) com.aspose.imaging.Image.load(dataDir + "file_000001.tif");

for (TiffFrame tiffFrame : tiffImage.getFrames()) {
    try (ByteArrayOutputStream outputStream = new ByteArrayOutputStream()) {
        if (tiffFrame.getFrameOptions().getBitsPerPixel() == 1) {
            tiffFrame.save(outputStream, new TiffOptions(TiffExpectedFormat.TiffCcittFax3));
            // or
            // tiffFrame.save(outputStream, new TiffOptions(TiffExpectedFormat.TiffCcittFax4));
        }
        outputStream.flush();
        
        try (ByteArrayInputStream inputStream = new ByteArrayInputStream(outputStream.toByteArray())) {
            Page page = pdfDocument.getPages().add();
            page.setPageSize(tiffFrame.getWidth(), tiffFrame.getHeight());
            ImageStamp imageStamp = new ImageStamp(inputStream);
            page.addStamp(imageStamp);
        }
    }
}

pdfDocument.save(dataDir + "output" + version + "_code2_TiffCcittFax3_.pdf");
