Java에서 TIFF를 PDF로 변환하는 방법

Input Images

Step 1: Add Imports to Java Main File

Begin by including the necessary imports in your Java main file to utilize IronPDF for TIFF to PDF conversion:

import com.ironsoftware.ironpdf.*;
import java.io.IOException;
import java.nio.file.DirectoryStream;
import java.nio.file.Files;
import java.nio.file.Path;
import java.nio.file.Paths;
import java.util.ArrayList;
import java.util.List;

import com.ironsoftware.ironpdf.*;
import java.io.IOException;
import java.nio.file.DirectoryStream;
import java.nio.file.Files;
import java.nio.file.Path;
import java.nio.file.Paths;
import java.util.ArrayList;
import java.util.List;

Step 2: Convert Single TIFF to PDF File

To convert a single TIFF image to a PDF file with just a few lines of code, follow the example below:

import com.ironsoftware.ironpdf.PdfDocument;
import java.nio.file.Path;
import java.nio.file.Paths;
import java.util.List;
import java.util.ArrayList;

public class TiffToPdfConverter {
    public static void main(String[] args) {
        // List to hold paths of images
        List<Path> paths = new ArrayList<>();

        // Adding a single TIFF image to the list of paths
        paths.add(Paths.get("assets/file_example_TIFF_1MB.tiff"));

        // Convert the TIFF image to a PDF and save it
        PdfDocument.fromImage(paths).saveAs(Paths.get("example.pdf"));
    }
}

import com.ironsoftware.ironpdf.PdfDocument;
import java.nio.file.Path;
import java.nio.file.Paths;
import java.util.List;
import java.util.ArrayList;

public class TiffToPdfConverter {
    public static void main(String[] args) {
        // List to hold paths of images
        List<Path> paths = new ArrayList<>();

        // Adding a single TIFF image to the list of paths
        paths.add(Paths.get("assets/file_example_TIFF_1MB.tiff"));

        // Convert the TIFF image to a PDF and save it
        PdfDocument.fromImage(paths).saveAs(Paths.get("example.pdf"));
    }
}

Step 3: Convert Multiple TIFFs into a PDF File

For converting multiple TIFF images into a single PDF document, use the following code:

import com.ironsoftware.ironpdf.PdfDocument;
import java.io.IOException;
import java.nio.file.DirectoryStream;
import java.nio.file.Files;
import java.nio.file.Path;
import java.nio.file.Paths;
import java.util.ArrayList;
import java.util.List;

public class MultiTiffToPdfConverter {
    public static void main(String[] args) {
        // Directory containing the TIFF images
        Path imageDirectory = Paths.get("assets");
        List<Path> imageFiles = new ArrayList<>();

        // Load all TIFF images from the directory
        try (DirectoryStream<Path> stream = Files.newDirectoryStream(imageDirectory, "*.{tiff}")) {
            for (Path entry : stream) {
                imageFiles.add(entry);
            }
            // Convert the TIFF images to a single PDF and save it
            PdfDocument.fromImage(imageFiles).saveAs(Paths.get("multiple_images.pdf"));
        } catch (IOException exception) {
            throw new RuntimeException(
                    String.format("Error converting images to PDF from directory: %s: %s",
                            imageDirectory,
                            exception.getMessage()),
                    exception);
        }
    }
}

import com.ironsoftware.ironpdf.PdfDocument;
import java.io.IOException;
import java.nio.file.DirectoryStream;
import java.nio.file.Files;
import java.nio.file.Path;
import java.nio.file.Paths;
import java.util.ArrayList;
import java.util.List;

public class MultiTiffToPdfConverter {
    public static void main(String[] args) {
        // Directory containing the TIFF images
        Path imageDirectory = Paths.get("assets");
        List<Path> imageFiles = new ArrayList<>();

        // Load all TIFF images from the directory
        try (DirectoryStream<Path> stream = Files.newDirectoryStream(imageDirectory, "*.{tiff}")) {
            for (Path entry : stream) {
                imageFiles.add(entry);
            }
            // Convert the TIFF images to a single PDF and save it
            PdfDocument.fromImage(imageFiles).saveAs(Paths.get("multiple_images.pdf"));
        } catch (IOException exception) {
            throw new RuntimeException(
                    String.format("Error converting images to PDF from directory: %s: %s",
                            imageDirectory,
                            exception.getMessage()),
                    exception);
        }
    }
}
