Basic Initialization

Begin by initializing the Editor class and setting up your document path:

String inputFilePath = "YOUR_DOCUMENT_DIRECTORY";
Editor editor = new Editor(inputFilePath, new WordProcessingLoadOptions());

Implementation Guide

We’ll break down the implementation into three main features: loading/editing documents, extracting resources, and saving them to the file system.

Loading and Editing a Document

Overview: Load a Word document and prepare it for editing using GroupDocs.Editor.

Initialize Editor: Create an Editor instance with the path to your Word document.
Edit Options Setup: Configure WordProcessingEditOptions to enable font extraction.
Editable Document Creation

// Initialize editor and edit options
String inputFilePath = "YOUR_DOCUMENT_DIRECTORY";
Editor editor = new Editor(inputFilePath, new WordProcessingLoadOptions());
WordProcessingEditOptions editOptions = new WordProcessingEditOptions();
editOptions.setFontExtraction(FontExtractionOptions.ExtractAll);
EditableDocument beforeEdit = editor.edit(editOptions);

Explanation: The FontExtractionOptions.ExtractAll parameter ensures all fonts are extracted during the editing process, providing comprehensive control over document formatting.

Extracting Resources from a Document

Overview: Extract images, fonts, and stylesheets for further processing or storage.

Extract Images

List<IImageResource> images = beforeEdit.getImages();

Extract Fonts

List<FontResourceBase> fonts = beforeEdit.getFonts();

Extract Stylesheets

List<CssText> stylesheets = beforeEdit.getCss();

Explanation: These methods retrieve all embedded resources, allowing you to handle each component separately.

Saving Resources to the File System

Overview: Store extracted resources into your desired directory for later use.

Save Images

String outputFolderPath = "YOUR_OUTPUT_DIRECTORY";
for (int i = 0; i < images.size(); i++) {
    IImageResource oneImage = images.get(i);
    File outputFile = new File(outputFolderPath + oneImage.getFilenameWithExtension());
    oneImage.save(outputFile.getAbsolutePath());
}

Save Fonts

for (int i = 0; i < fonts.size(); i++) {
    FontResourceBase oneFont = fonts.get(i);
    File outputFile = new File(outputFolderPath + oneFont.getFilenameWithExtension());
    oneFont.save(outputFile.getAbsolutePath());
}

Save Stylesheets

for (int i = 0; i < stylesheets.size(); i++) {
    CssText oneStylesheet = stylesheets.get(i);
    File outputFile = new File(outputFolderPath + oneStylesheet.getFilenameWithExtension());
    oneStylesheet.save(outputFile.getAbsolutePath());
}

Explanation: These loops iterate over each resource type, saving them individually to maintain organization and accessibility.

Retrieving Resource Content

To access the content of an image as a byte stream or base64-encoded string:

InputStream ms = images.get(0).getByteContent(); // For further processing
String base64EncodedResource = images.get(0).getTextContent();

Explanation: This snippet demonstrates how to retrieve and use resource contents in different formats, essential for data manipulation tasks.

Practical Applications

Document Archiving: Automate the archiving of document resources with metadata tagging.
Custom Document Templates: Extract and reuse stylesheets across multiple documents for brand consistency.
Dynamic Content Generation: Integrate extracted images into web applications or reports dynamically.
Compliance and Auditing: Maintain a record of all fonts used in legal documents to ensure compliance.

Performance Considerations

Optimize Resource Management: Ensure resources are disposed of properly using dispose() methods to free up memory.
Batch Processing: Handle large batches of documents efficiently by processing them in smaller chunks.
Monitor Memory Usage: Use Java profiling tools to monitor and manage memory consumption when dealing with extensive documents.
