Convertir los datos del proyecto a PDF

Aspose.Tasks for C ++ API proporciona la capacidad de representar los datos del proyecto al formato PDF. Este artículo ofrece una descripción detallada de la variedad de opciones disponibles en Aspose.Tasks para exportar proyectos a PDF.

Guardar un proyecto como PDF

La clase Proyecto expone el método Guardar que se utiliza para guardar un proyecto en varios formatos. El método Guardar le permite representar datos del proyecto a PDF utilizando el tipo de enumeración SaveFileFormat.

Para guardar un proyecto en PDF:

1. Cargue un archivo de proyecto de Microsoft.
2. Guarde el proyecto en PDF usando SaveFileFormat.pdf.

Las siguientes líneas de código demuestran cómo lograr esto usando C ++.

// Read the input Project file
System::SharedPtr<Project> project = System::MakeObject<Project>(dataDir + u"CreateProject2.mpp");
    
// Save the Project as PDF
project->Save(dataDir + u"SaveProjectAsPDF_out.pdf", Aspose::Tasks::Saving::SaveFileFormat::PDF);

Fitting Contents to Cell Size

It is common that a task (or resource) name is so long that it is truncated when project views are rendered. Aspose.Tasks for C++ API provides the FitContent property in the SaveOptions class to avoid truncation of task and resource names. The code example given below renders a project to PDF format with the FitContent property set to true.

System::SharedPtr<Project> project = System::MakeObject<Project>(dataDir + u"CreateProject2.mpp");
System::SharedPtr<SaveOptions> saveOptions = System::MakeObject<PdfSaveOptions>();
    
// Set option fit content to true
saveOptions->set_FitContent(true);
saveOptions->set_Timescale(Aspose::Tasks::Visualization::Timescale::Months);
saveOptions->set_PresentationFormat(Aspose::Tasks::Visualization::PresentationFormat::TaskUsage);
project->Save(dataDir + u"FitContentsToCellSize_out.pdf", saveOptions);

Printing or Hiding Legends when Rendering

To let you print or hide the legends on each page, the SaveOptions class provides the LegendOnEachPage property. If this flag is set to true, legends are printed on each page in the output file.

System::SharedPtr<SaveOptions> saveOptions = System::MakeObject<PdfSaveOptions>();
    
// Set the LegendOnEachPage property to false to hide legends
saveOptions->set_LegendOnEachPage(false);

Supported Graphical Column Indicators

Aspose.Tasks for C++ API draws graphical column indicators when rendering project data to output PDF. The following graphical indicators are supported by Aspose.Tasks:

Indicator Type	Graphical Indicator
Task Indicators
Resource Indicators
Assignment Indicators

Saving to Multiple PDF Files

To save project data to multiple PDF files, set the SaveToSeparateFiles flag to true.

System::SharedPtr<Project> project = System::MakeObject<Project>(dataDir + u"Software Development Plan.mpp");
System::SharedPtr<PdfSaveOptions> saveOptions = System::MakeObject<PdfSaveOptions>();
saveOptions->set_SaveToSeparateFiles(true);
saveOptions->set_Pages(System::MakeObject<System::Collections::Generic::List<int32_t>>());
saveOptions->get_Pages()->Add(1);
saveOptions->get_Pages()->Add(4);
project->Save(dataDir + u"SaveToMultiplePDFFiles_out.pdf", System::StaticCast<Aspose::Tasks::Saving::SaveOptions>(saveOptions));

Customizing TextStyle for Project Data

Aspose.Tasks for C++ API allows developers to customize the text style for overallocated resources. By default, the style used for overallocated resources is similar to Microsoft Project (MSP), that is, red and bold. TextItemType.OverallocatedResources makes it possible to customize the color and style for the overallocated resources.

System::SharedPtr<Project> project = System::MakeObject<Project>(dataDir + u"CreateProject2.mpp");
System::SharedPtr<SaveOptions> options = System::MakeObject<PdfSaveOptions>();
options->set_PresentationFormat(Aspose::Tasks::Visualization::PresentationFormat::ResourceSheet);
    
System::SharedPtr<TextStyle> style = System::MakeObject<TextStyle>();
style->set_Color(System::Drawing::Color::get_OrangeRed());
style->set_FontStyle(System::Drawing::FontStyle::Bold);
System::setter_or_wrap(style.GetPointer(), &TextStyle::get_FontStyle, &TextStyle::set_FontStyle, System::Drawing::FontStyle::Italic);
style->set_ItemType(Aspose::Tasks::Visualization::TextItemType::OverallocatedResources);
    
options->set_TextStyles(System::MakeObject<System::Collections::Generic::List<System::SharedPtr<TextStyle>>>());
options->get_TextStyles()->Add(style);
project->Save(dataDir + u"CustomizeTextStyle_out.pdf", options);

Customizing Date Formats

Aspose.Tasks for C++ API allows developers to customize the date format using the DateFormat enumerator when rendering project data.

System::SharedPtr<Project> project = System::MakeObject<Project>(dataDir + u"CreateProject2.mpp");
    
auto options = [&]{ auto tmp_0 = System::MakeObject<PdfSaveOptions>(); tmp_0->set_PresentationFormat(Aspose::Tasks::Visualization::PresentationFormat::GanttChart); tmp_0->set_FitContent(true); tmp_0->set_UseProjectDefaultFont(false); tmp_0->set_DefaultFontName(u"Segoe UI Black"); return tmp_0; }();
project->Save(dataDir + u"CreateProject2_out.pdf", System::StaticCast<Aspose::Tasks::Saving::SaveOptions>(options));

Setting Default Font

Setting default font during rending of documents helps when a font is not found. In such a case, the default font replaces the missing font, and output is not affected. Aspose.Tasks for C++ API lets you specify the default font using the DefaultFontName property of the PdfSaveOptions as shown in the following code sample.

System::SharedPtr<Project> project = System::MakeObject<Project>(dataDir + u"CreateProject2.mpp");
project->Set(Prj::StartDate(), System::DateTime(2014, 9, 22));
    
// By default project.DateFormat == DateFormat.Date_ddd_mm_dd_yy (Mon 09/22/14) customize DateFormat (September 22, 2014)
project->Set<DateFormat>(Prj::DateFormat(), Aspose::Tasks::DateFormat::DateMmmmDdYyyy);
project->Save(dataDir + u"CustomizeDateFormats1_out.pdf", Aspose::Tasks::Saving::SaveFileFormat::PDF);
    
// Export to date format 19/07/2016
project->Set<DateFormat>(Prj::DateFormat(), Aspose::Tasks::DateFormat::DateDdMmYyyy);
project->Save(dataDir + u"CustomizeDateFormats2_out.pdf", Aspose::Tasks::Saving::SaveFileFormat::PDF);
