Travailler avec le pied de page d'en-tête de page

Lecture des informations d’en-tête et de pied de page du fichier MPP

Aspose.Tasks pour l’API .NET offre la capacité de lire les informations d’en-tête et de pied de page du fichier MPP. L’API a des classes mappées à chaque onglet de la boîte de dialogue de configuration de la page du projet Microsoft comme détaillé dans la section ci-dessous.

• La boîte de dialogue de configuration de la page du projet Microsoft a 6 onglets. Ces onglets sont mappés à de nouvelles classes:- Page tab -> Aspose.Tasks.Visualization.PageSettings class
  • Margins tab -> Aspose.Tasks.Visualization.PageMargins class
  • Header, footer tabs -> Aspose.Tasks.Visualization.HeaderFooterInfo class
  • Legend tab -> Aspose.Tasks.Visualization.PageLegend class
  • View tab -> Aspose.Tasks.Visualization.PageViewSettings class

Adding Image to Page Header/Footer

Aspose.Tasks for .NET API provides the capability to manipulate the document’s page header and footer information. The example below shows how to add image to page’s header.

Project project = new Project("New Project.mpp");

project.RootTask.Children.Add("Task1");
PageInfo pageInfo = project.DefaultView.PageInfo;

using (Image image = Image.FromFile("Image1.png"))
{
    pageInfo.Header.CenteredImage = image;
    pageInfo.Legend.LeftImage = image;
    pageInfo.Legend.LeftText = string.Empty;
    MPPSaveOptions options = new MPPSaveOptions();
    options.WriteViewData = true;
    project.Save("AddImageToPageHeaderFooter_out.mpp", options);
}
