Public API changes

This section lists public API changes that were introduced in Aspose.HTML for .NET 18.7. It includes not only new and obsoleted public methods, but also a description of any changes in the behavior behind the scenes in Aspose.HTML which may affect existing code. Any behavior introduced that could be seen as a regression and modifies existing behavior is especially important and is documented here.

Added APIs:

Introduced a new type of Aspose.Html.Forms namespace: ButtonElement object.

 /// <summary>

///  The ButtonElement represents a wrapper that is associated with the HTMLButtonElement.

/// </summary>

public class ButtonElement: FormElement<HTMLButtonElement>

{

    /// <summary>

    /// Represent the name attribute of the Button element.

    /// </summary>

    public override string Name { get; set; }

    /// <summary>

    /// Represents the Id attribute of the Button element.

    /// </summary>

    public override string Id { get; set; }

    /// <summary>

    /// Represents the string value of the button element that is directly mapped to the 'value' attribute.

    /// </summary>

    public override string Value { get; set; }

    /// <summary>

    /// Type of the form control.

    /// </summary>

    public ButtonType Type { get; set; }

}

Added CSSMarginRule object according to CSS specification.

 public interface ICSSMarginRule : ICSSRule

{

    /// <summary>

    /// The name attribute must return the name of the margin at-rule.

    /// </summary>

    string Name { get; }

    /// <summary>

    /// The declaration-block of this rule.

    /// </summary>

    ICSSStyleDeclaration Style { get; }

}

Added the overridden methods to the FormSubmitter object that allow to specify CookieContainer during the web request/response operations.

 public class FormSubmitter

{

    /// <summary>

    /// Submits the form data to the server with specified cookies.

    /// </summary>

    public SubmissionResult Submit(CookieContainer cookieContainer) {}

    /// <summary>

    ///  Submits the form data to the server with specified user credentials and cookies.

    /// </summary>

    public SubmissionResult Submit(ICredentials credentials, CookieContainer cookieContainer) {}

    /// <summary>

    /// Submits the form data to the server with specified user credentials and cookies.

    /// </summary>

    public SubmissionResult Submit(ICredentials credentials, TimeSpan timeout, bool preAuthenticate, CookieContainer cookieContainer) {}

}

The ResponseMessage object has been changed and now supports CookieContainer property.

 namespace Aspose.Html.Net

{

    /// <summary>

    /// Represents a response message.

    /// </summary>

    /// <seealso cref="System.IDisposable" />

    public class ResponseMessage : IDisposable

    {

        /// <summary>

        /// Gets or sets the cookie collection.

        /// </summary>

        public CookieCollection Cookies { get; set; }

    }

}

The abstract renderer object has been extended with ability to render multiple documents into a single output device; all derived classes HtmlRenderer, SvgRenderer, MhtmlRenderer and EpubRenderer have been extended as well.

 public abstract class Renderer<TDocument> : Renderer

{

    /// <summary>

    /// Defines method for rendering multiple <see cref="TDocument"/>s into specific <see cref="IDevice" />.

    /// </summary>

    public abstract void Render(IDevice device, params TDocument[] documents);

}
