try (Viewer viewer = new Viewer("YOUR_ARCHIVE_FILE_PATH")) {
    // Configure options here
} catch (Exception e) {
    e.printStackTrace();
}

Implementation Guide

Now, let’s focus on specifying filenames when rendering archives to PDFs.

Specifying Filename When Rendering Archive Files

This feature allows you to customize the output filename of your rendered PDF document. Here’s how:

Step 1: Define Output Directory and File Path

Start by setting up the output directory and file path using placeholders for easy customization:

import java.nio.file.Path;
// Define output directory and file path
Path outputDirectory = Path.of("YOUR_OUTPUT_DIRECTORY");
Path outputFilePath = outputDirectory.resolve("output.pdf");

Step 2: Initialize Viewer Object

Create a Viewer object with the archive file you wish to render:

import com.groupdocs.viewer.Viewer;
try (Viewer viewer = new Viewer("YOUR_DOCUMENT_DIRECTORY/SAMPLE_ZIP")) {
    // Continue to next steps
} catch (Exception e) {
    e.printStackTrace();
}

Step 3: Create PdfViewOptions

Set up PdfViewOptions to specify the rendering configurations:

import com.groupdocs.viewer.options.PdfViewOptions;
// Configure PDF view options
PdfViewOptions viewOptions = new PdfViewOptions(outputFilePath);

Step 4: Set Custom Filename

Use ArchiveOptions to set a custom filename for your rendered PDF document:

import com.groupdocs.viewer.options.FileName;
import com.groupdocs.viewer.options.ArchiveOptions;
// Specify the output PDF filename
viewOptions.getArchiveOptions().setFileName(new FileName("my_custom_filename.pdf"));

Step 5: Render Archive File to PDF

Finally, render your archive file using the specified options:

// Execute rendering process
viewer.view(viewOptions);

Troubleshooting Tips

  • Ensure all paths are correctly set and directories exist.
  • Verify that you have the correct version of GroupDocs.Viewer installed.

Practical Applications

Understanding how to specify filenames when rendering archives can be beneficial in various scenarios:
