Save(Stream, SaveOptions)

Saves the drawing in the specified stream.

public void Save(Stream stream, SaveOptions options)
Public Sub Save(stream As Stream, options As SaveOptions)
Parameters
stream
System.IO.Stream

The stream in which to save the drawing.

options
SaveOptions

The saving options which can be used to define settings for save operation.

Remarks

Parameter options, currently, must be of type PdfSaveOptions, XpsSaveOptions or ImageSaveOptions.

Save(Object, String)

Saves the drawing to a System.Web.HttpResponse or System.Web.HttpResponseBase output stream or a System.Net.Http.HttpResponseMessage and sets appropriate HTTP response headers (Content-Type and Content-Disposition). Use this method in ASP.NET application to send the drawing to a client browser. File format is resolved from fileName extension. See remarks why httpResponse parameter is of type System.Object.

public void Save(object httpResponse, string fileName)
Public Sub Save(httpResponse As Object, fileName As String)
Parameters
httpResponse
System.Object

System.Web.HttpResponse object that can be retrieved through the Response property of the System.Web.HttpApplication, System.Web.HttpContext, System.Web.UI.Page or System.Web.UI.UserControl classes or System.Web.HttpResponseBase object or System.Net.Http.HttpResponseMessage object.

fileName
System.String

File name that will be presented in client browser when downloading a file.

Remarks
note

Supported only if updating the whole page with a postback and not if doing partial-page updates (when you use UpdatePanel controls to update selected regions of a page).

This method accepts System.Object rather than HttpResponse, HttpResponseBase or HttpResponseMessage because otherwise GemBox.Document assembly would have a dependency on System.Web or System.Net.Http assemblies and could not be used in applications which target Client Profile .NET Framework.

HttpResponse can be retrieved through the Response property of the HttpApplication, HttpContext, Page or UserControl classes.

For supported file extensions, see remarks for Save(String) method.

Exceptions
System.InvalidOperationException

If file extension is not specified or not supported. If file extension is not recognized, use Save(Object, String, SaveOptions) method overload instead.

Save(Object, String, SaveOptions)
