Public API and backward incompatible changes

To simplify and clarify the API, we have separated the web document rendering options into the WebDocumentOptions class. In previous versions, you had to use the WordProcessingOptions class, which was not intuitive.

public class WebDocumentOptions {

    public WebDocumentOptions() {
        // Implementation
    }

    public PageSize getPageSize() {
        // Implementation
    }

    public void setPageSize(PageSize pageSize) {
        // Implementation
    }

    public float getLeftMargin() {
        // Implementation
    }

    public void setLeftMargin(float leftMargin) {
        // Implementation
    }

    public float getRightMargin() {
        // Implementation
    }

    public void setRightMargin(float rightMargin) {
        // Implementation
    }

    public float getTopMargin() {
        // Implementation
    }

    public void setTopMargin(float topMargin) {
        // Implementation
    }

    public float getBottomMargin() {
        // Implementation
    }

    public void setBottomMargin(float bottomMargin) {
        // Implementation
    }
}

The following code snippet demonstrates how to set Web document options when rendering HTML file to PDF:

try (Viewer viewer = new Viewer("Invoice.htm")) {
    // Create a PDF file for with page size set to A3 1190 x 842 points.
    PdfViewOptions viewOptions = new PdfViewOptions("output.pdf");
    viewOptions.getWebDocumentOptions().setPageSize(PageSize.A3); 
    viewer.view(viewOptions);
}
