Integrate Aspose.Pdf with Aspose.Chart

Aspose.Chart and Aspose.Pdf

 

Aspose.Chart is a specialized product by Aspose to produce professional charts of many types. If developers need to add Chart objects from Aspose.Chart to their PDF documents, it is possible. Currently, the Chart object cannot be added directly to the Document Object Model of Aspose.Pdf but there is another way to do so which is explained in next section.

 

How to Add Chart in PDF?

 

Developers need to understand the steps below to perform this task:

 

• Developers would need to create a Chart object using Aspose.Chart
• Save the Chart
• Create a MemoryStream object and Save the Bitmap image to MemoryStream
• Finally, developers may create a Pdf document using Aspose.Pdf and add an Image to it. Set the ImageFileType to ImageFileType.MemoryBmp and ImageStream of Image to ImageOpenType.Memory ( where ImageFileType is enumeration in Aspose.Pdf ).

 

After performing the steps above, you are done and the Chart will be added to Aspose.Pdf as an Image .

 

Code Snippet

 

[C#]

 

 

   Chart chart = new Chart();

   chart.SmoothingMode = System.Drawing.Drawing2D.SmoothingMode.HighQuality;

 

 

   Series s = new Series();

   s.ChartType = ChartType.Bar;

   s.DataPoints.Add(new DataPoint(2, -2));

   s.DataPoints.Add(new DataPoint(4,  7));

   s.DataPoints.Add(new DataPoint(6, -9));

   chart.SeriesCollection.Add(s);

 

 

   System.IO.MemoryStream mstream = new System.IO.MemoryStream();

   chart.Save(mstream,System.Drawing.Imaging.ImageFormat.Png);

 

 

   Pdf pdf = new Pdf();

 

 

   Section sec = pdf.Sections.Add();

 

 

   Image img = new Image();

   img.ImageInfo.ImageFileType = ImageFileType.Png;

   img.ImageInfo.ImageStream = mstream;

 

 

   sec.Paragraphs.Add(img);

 

 

   pdf.Save("Chart.pdf");

 

 

[VB.NET]

 

 

'Create a chart object using Aspose.Chart and set its smoothing mode to

'high quality

Dim chart As Chart = New Chart()

chart.SmoothingMode = SmoothingMode.HighQuality

 

 

'Set the chart as bart chart and plot the data points on the chart using Series

Dim s As Series = New Series()

s.ChartType = ChartType.Bar

s.DataPoints.Add(new DataPoint(2, -2))

s.DataPoints.Add(new DataPoint(4,  7))

s.DataPoints.Add(new DataPoint(6, -9))

chart.SeriesCollection.Add(s) 

 

 

'Save the chart as Bitmap image

Dim bm As Bitmap = chart.Save()

 

 

'Create a MemoryStream object and save th Bitmap image to it

Dim mstream As System.IO.MemoryStream = New System.IO.MemoryStream()

bm.Save(mstream, System.Drawing.Imaging.ImageFormat.Png)

 

 

Dim pdf1 As Pdf = New Pdf()

Dim sec1 As Section = pdf1.Sections.Add()

 

 

Dim img As Image = new Image(sec1)

image1.ImageInfo.ImageFileType = ImageFileType.Png

image1.ImageInfo.ImageStream = msstream

sec1.Paragraphs.Add(image1)

 

 

pdf1.Save("Chart.pdf");
