Public API Changes

Support of the shape points editing has been added

Support of the shape points editing has been added. New classes, interfaces, enums, and GeometryShape methods have been added.

New classes:

New interfaces:

New enums:

Public methods have been added to the GeometryShape class and its descendants:

Feature description:

Customization of the shape geometry assumes editing points of an existing shape.

Edit shape points

To provide the mentioned functionality GeometryPath class and IGeometryPath interface have been added. GeometryPath instance represents a geometry path of the IGeometryShape object.

To retrieve GeometryPath from the IGeometryShape instance GeometryPath method has been added. Please note that shapes may be built from a few smaller shapes (e.g. an “equal” sign) so this method returns an array of IGeometryPath objects.

To set GeometryPath to the shape two methods have been added: IGeometryShape.SetGeometryPath(IGeometryPath geometryPath) for solid shapes and SetGeometryPaths(IGeometryPath[] geometryPaths) for composite shapes.

IOutput.BindResource method has been added

BindResource method has been added to IOutput interface.

Method declaration:

/// <summary>
/// Binds resource to output file.
/// </summary>
/// <param name="outputFile">Output file.</param>
/// <param name="obj">Resource object.</param>
void BindResource(IOutputFile outputFile, object obj);

Return type of all IOutput.Add method overloads has been changed

Return type of all Add method overloads in IOutput interface has been changed from void to IOutputFile. All these methods now return IOutputFile object that has been created during adding to output.

New declaration of all IOutput.Add methods:

/// <summary>
/// Adds an output element for the context object.
/// </summary>
/// <param name="path">Output path.</param>
/// <param name="templateKey">The key of the template used for context object transformation before output.</param>
/// <param name="contextObject">Context object.</param>
/// <returns><see cref="IOutputFile"/> object for the context object.</returns>
IOutputFile Add<TContextObject>(string path, string templateKey, TContextObject contextObject);

/// <summary>
/// Adds an output element for the image.
/// </summary>
/// <param name="path">Output path.</param>
/// <param name="image">Image to output.</param>
/// <returns><see cref="IOutputFile"/> object for the image.</returns>
IOutputFile Add(string path, IPPImage image);

/// <summary>
/// Adds an output element for the image.
/// </summary>
/// <param name="path">Output path.</param>
/// <param name="image">Image to output.</param>
/// <returns><see cref="IOutputFile"/> object for the image.</returns>
IOutputFile Add(string path, Image image);

/// <summary>
/// Adds an output element for the font.
/// </summary>
/// <param name="path">Output path.</param>
/// <param name="font">Font to output.</param>
/// <param name="fontStyle">Font style.</param>
/// <returns><see cref="IOutputFile"/> object for the font.</returns>
IOutputFile Add(string path, IFontData font, FontStyle fontStyle);

/// <summary>
/// Adds an output element for the video.
/// </summary>
/// <param name="path">Output path.</param>
/// <param name="video">Video to output.</param>
/// <returns><see cref="IOutputFile"/> object for the video.</returns>
IOutputFile Add(string path, IVideo video);

/// <summary>
/// Adds an output element for the text content.
/// </summary>
/// <param name="path">Output path.</param>
/// <param name="textContent">Content to output.</param>
/// <returns><see cref="IOutputFile"/> object for the text content.</returns>
IOutputFile Add(string path, string textContent);

Two IOutput.Add method overloads have been added

Two Add method overloads have been added to IOutput.

Methods declaration:

/// <summary>
/// Adds an output element for the text content.
/// </summary>
/// <param name="path">Output path.</param>
/// <param name="textContent">Content to output.</param>
/// <returns>IOutputFile for the text content.</returns>
IOutputFile Add(string path, string textContent);

/// <summary>
/// Adds an output element for the image.
/// </summary>
/// <param name="path">Output path.</param>
/// <param name="image">Image to output.</param>
/// <returns><see cref="IOutputFile"/> object for the image.</returns>
IOutputFile Add(string path, Image image);

The first method overload adds an output element for the text content. It can be used to add custom javascript, css, html files to your document output. The second method overload adds an output element for the image. It can be used to add arbitrary image to your document output.

Methods usage example (adding hello world html page with presentation first slide preview):

Presentation pres = new Presentation();
WebDocumentOptions options = new WebDocumentOptions();
WebDocument document = new WebDocument(options);

string htmlContent = "<html><head><title>Sample page</title></head><body><h1>Just a sample page. Hello world!</h1><br/><img src="thumbnail.png"/></body></html>";
Bitmap thumbnail = pres.Slides[0].GetThumbnail();

document.Output.Add("index.html", htmlContent);
document.Output.Add("thumbnail.png", thumbnail);

document.Save();

Two IOutput.Add method overloads have been removed

Two Add method overloads have been removed from IOutput interface.

Removed methods signatures:

void Add(string path, IOutputFile outputFile);
void Add(string path, IOutputFile outputFile, object obj);
