Extract images from document page area Leave feedback

GroupDocs.Parser provides the functionality to extract images from document page area by the by the getImages(PageAreaOptions) and getImages(int, PageAreaOptions) methods:

Iterable<PageImageArea> getImages(PageAreaOptions options);
Iterable<PageImageArea> getImages(int pageIndex, PageAreaOptions options);

This method returns a collection of PageImageArea objects:

ImageOptions class is used to define the image format into which the image is converted. The following image formats are supported:

• Bmp
• Gif
• Jpeg
• Png
• WebP

PageAreaOptions parameter is used to customize text areas extraction process. This class has the following members:

Here are the steps to extract images from the upper-left corner:

• Instantiate Parser object for the initial document;
• Instantiate PageAreaOptions with the rectangular area;
• Call getImages(PageAreaOptions) method and obtain collection of PageImageArea objects;
• Check if collection isn’t null (images extraction is supported for the document);
• Iterate through the collection and get sizes, image types and image contents.

The following example shows how to extract only images from the upper-left corner:

// Create an instance of Parser class
try (Parser parser = new Parser(Constants.SampleImagesPdf)) {
    // Create the options which are used for images extraction
    PageAreaOptions options = new PageAreaOptions(new Rectangle(new Point(340, 150), new Size(300, 100)));
    // Extract images from the upper-left corner of a page:
    Iterable<PageImageArea> images = parser.getImages(options);
    // Check if images extraction is supported
    if (images == null) {
        System.out.println("Page images extraction isn't supported");
        return;
    }
    // Iterate over images
    for (PageImageArea image : images) {
        // Print a page index, rectangle and image type:
        System.out.println(String.format("Page: %d, R: %s, Type: %s", image.getPage().getIndex(), image.getRectangle(), image.getFileType()));
    }
}
