Hi,

How can I get postion and size of a Portion? I used to work with PowerPoint automation and can get those values via PowerPoint.TextRange (use BoundHeight, BoundWidth, BoundLeft and BoundTop properties).

I’m stuck at this. Please help.

Thanks

Dear phucbui,

Thanks for using Aspose.Slides.

You cannot get them via Aspose.Slides. However, you can get X, Y, Heigh and Width of overall TextFrame.

@phucbui,

Earlier, Aspose.Slides provided support for getting coordinates for any text on text frame level. However, now API has introduced the support for getting the coordinates position, width and height of text belonging to any text frame on paragraph as well as on portion level. Using few simple API calls, you can serve the purpose on your end. In the following examples, we have demonstrated the use of the new features for your convenience.

	public static void GetParagraphCoordinates()
	{
		// The path to the documents directory.
		string dataDir = @"C:\Aspose Data\";

		// Instantiate a Presentation object that represents a presentation file
		using (Presentation presentation = new Presentation(dataDir + "TestText.pptx"))
		{
			IAutoShape shape = (IAutoShape)presentation.Slides[0].Shapes[0];
			var textFrame = (ITextFrame)shape.TextFrame;
			RectangleF rect = ((Paragraph)textFrame.Paragraphs[0]).GetRect();
			Console.WriteLine("The following shows the paragraph's actual coordinates on slide");
			Console.WriteLine(String.Format("Paragraph Text: {4} has coordinates (X: {0}, Y: {1}), Width: {2} and Height{3}", rect.X, rect.Y, rect.Width, rect.Height, ((Paragraph)textFrame.Paragraphs[0]).Text));
		}
	}

	public static void GetPortionCoordinates()
	{
		string dataDir = @"C:\Aspose Data\";
		using (Presentation presentation = new Presentation(dataDir + "TestText.pptx"))
		{
			IAutoShape shape = (IAutoShape)presentation.Slides[0].Shapes[0];
			var textFrame = (ITextFrame)shape.TextFrame;

			foreach (var paragraph in textFrame.Paragraphs)
			{
				Console.WriteLine("The following shows the coordinates for all the portions inside paragraph");

				foreach (Portion portion in paragraph.Portions)
				{
					var rect = portion.GetRect();//.GetCoordinates();
					//Console.Write(Environment.NewLine + "Corrdinates X =" + point.X + " Corrdinates Y =" + point.Y);
					Console.WriteLine(String.Format("Portion Text: {4} has coordinates (X: {0}, Y: {1}), Width: {2} and Height{3}", rect.X, rect.Y, rect.Width, rect.Height, portion.Text));
				}
			}
		}
	}
