Rendering Task Usage View

Aspose.Tasks for Java supports rendering project tasks to a variety of formats, such as PDF. Task usage can be rendered using Aspose.Tasks’ PresentationFormat with different timescale settings like Days, ThirdOfMonths and Months.

Rendering Task Usage View

The code snippet in this article reads a source MPP file that has several tasks with assigned resources and renders these to output PDF using the following steps:

1. Create an instance of Project Reader.
2. Read the source MPP file.
3. Initiate the SaveOptions object with the required timescale settings.
4. Set the presentation format to TaskUsage.
5. Render the project to PDF output.

// For complete examples and data files, please go to https://github.com/aspose-tasks/Aspose.Tasks-for-Java
// The path to the documents directory.
String dataDir = Utils.getDataDir(RenderTaskUsage.class);
//Read the source Project
Project project = new Project(dataDir + "RenderMe.mpp");
//Define the SaveOptions with required TimeScale settings as Days
SaveOptions options = new PdfSaveOptions();
options.setTimescale(Timescale.Days);
//Set the Presentation format to ResourceUsage
options.setPresentationFormat(PresentationFormat.TaskUsage);
String days = "result_days.pdf";
//Save the Project
project.save(days, options);

//Set the Tiemscale settings to ThirdsOfMonths
options.setTimescale(Timescale.ThirdsOfMonths);
String thirds = "result_thirdsOfMonths.pdf";
//Save the Project
project.save(thirds, options);

//Set the Timescale settings to Months
options.setTimescale(Timescale.Months);
String months = "result_months.pdf";
//Save the project
project.save(months, options);

Rendering Details Column to Output in Task Usage View

The details column included in the MPP file can be rendered to the output using the View’s DisplayDetailsHeaderColumn property. The following code sample illustrates the usage of this property.

// For complete examples and data files, please go to https://github.com/aspose-tasks/Aspose.Tasks-for-Java
// The path to the documents directory.
String dataDir = Utils.getDataDir(RenderTaskUsage.class);
Project project = new Project(dataDir + "Advanced Tracking C_Start.mpp"); // attached test project
// Default view in this mpp is TaskUsageView
UsageView view = (UsageView) project.getDefaultView();// as TaskUsageView;

// details header column will not be displayed
view.setDisplayDetailsHeaderColumn(false);
view.setRepeatDetailsHeaderOnAllRows(false);
view.setAlignDetailsData(StringAlignment.Near);
project.save("task usage1.pdf", SaveFileFormat.PDF);

// display details header column
view.setDisplayDetailsHeaderColumn(true);
// Repeat details header on all assignments rows
view.setRepeatDetailsHeaderOnAllRows(true);
view.setAlignDetailsData(StringAlignment.Far);
project.save("task usage2.pdf", SaveFileFormat.PDF);
project.save("task usage2.pdf", SaveFileFormat.PDF);
