Add text overlay

GroupDocs.Viewer provides feature that allows to add text overlays over images. This feature is useful if you want to add selectable text over the image or implement a text search in image-based rendering.

Please note that due to Image Viewer’s architecture rendering results with text extraction enabled and disabled are different.

The setExtractText() property of PngViewOptions (or setExtractText() property of JpgViewOptions) class enables you to render document to display with text.

This example demonstrates how to render document for display with text.

    try (Viewer viewer = new Viewer("sample.docx")) {
        PngViewOptions viewOptions = new PngViewOptions();
        viewOptions.setExtractText(true);
        viewer.view(viewOptions);
    }
