Aspose.Tasks提供根據不同時間尺度的設置來渲染甘特圖的功能。根據這些時間刻度設置（包括日，月，季度）有多個選項可用來渲染甘特圖圖像。使用這些選項可以將甘特圖渲染進一張圖片中。本文詳細描述了這一過程。

ImageSaveOptions類的Timescale屬性決定了項目的Timescale時間尺度設置。這個時間尺度默認為天,當然也可使用月或著季度為單位。下面是代碼示例:

• 讀取一個項目文件
• 使用不同的時間尺度進行設置
• 將文件保存為圖像形式進行輸出

C#

Project project = new ProjectReader().Read("NewProductDev.mpp");

// Save to one page image (Timescale.days by default)
project.Save("NewProductDevDays.jpeg", new ImageSaveOptions(SaveFileFormat.JPEG));


// Save to one page image (Timescale.ThirdsOfMonths)
ImageSaveOptions options = new ImageSaveOptions(SaveFileFormat.JPEG);
options.Timescale = Timescale.ThirdsOfMonths;

project.Save("NewProductDevThirdsOfMonths.jpeg", options);

// Save to one page image (Timescale.Months)
options.Timescale = Timescale.Months;
project.Save("NewProductDevMonths.jpeg", options);

// There is IRender property for compliance with Project.Export interface
options.RenderParam = new BaseImageRenderParam(null, Point.Empty, new Size(800, 600), 100, 0, true);

project.Save("NewProductDevRenderOptions.jpeg", options);

VB.NET

Dim project As Project = New ProjectReader().Read("NewProductDev.mpp")

'Save to one page image (Timescale.days by default)
project.Save("NewProductDevDays.jpeg", New ImageSaveOptions(SaveFileFormat.JPEG))

'Save to one page image (Timescale.ThirdsOfMonths)
Dim options As ImageSaveOptions = New ImageSaveOptions(SaveFileFormat.JPEG)
options.Timescale = Timescale.ThirdsOfMonths

project.Save("NewProductDevThirdsOfMonths.jpeg", options)

'Save to one page image (Timescale.Months)
options.Timescale = Timescale.Months
project.Save("NewProductDevMonths.jpeg", options)

'There is IRender property for compliance with Project.Export interface
Dim baseImageRenderParam As BaseImageRenderParam = New BaseImageRenderParam(Nothing, Point.Empty, New Size(800, 600), 100, 0, True)

project.Save("NewProductDevRenderOptions.jpeg", options)
