Public API Changes

Slides on Android via Xamarin

Xamarin is the set of tools and libraries that extend .NET and allows to build applications for Android using C# and Visual Studio. We have added support for Xamarin platform, and now you can use it to build your C# application with Aspose.Slides for Android.

Get Text Location in a Table Cell

Method IPortion.GetRect() has been added. This method extends and actually replaces method IPortion.GetCoordinates() which is marked as obsolete now.

Methods IPortion.GetRect() and IParagraph.GetRect() can be applied to text within table cells. The following example shows how the properties work.

Let’s say, we have a table with some text inside and a simple AutoShape nearby.

todo:image_alt_text

The code snippet below generates these objects:

using (Presentation pres = new Presentation())
{
	ITable tbl = pres.Slides[0].Shapes.AddTable(50, 50, new double[] { 50, 70 }, new double[] { 50, 50, 50 });
	IParagraph paragraph0 = new Paragraph();
	paragraph0.Portions.Add(new Portion("Text "));
	paragraph0.Portions.Add(new Portion("in0"));
	paragraph0.Portions.Add(new Portion(" Cell"));

	IParagraph paragraph1 = new Paragraph();
	paragraph1.Text = "On0";

	IParagraph paragraph2 = new Paragraph();
	paragraph2.Portions.Add(new Portion("Hi there "));
	paragraph2.Portions.Add(new Portion("col0"));

	ICell cell = tbl.Rows[1][1];
	cell.TextFrame.Paragraphs.Clear();
	cell.TextFrame.Paragraphs.Add(paragraph0);
	cell.TextFrame.Paragraphs.Add(paragraph1);
	cell.TextFrame.Paragraphs.Add(paragraph2);

    IAutoShape autoShape = pres.Slides[0].Shapes.AddAutoShape(ShapeType.Rectangle, 400, 100, 60, 120);
	autoShape.TextFrame.Text = "Text in shape";
}

The source code snippet below will add a yellow frame to all paragraphs and a blue frame to all portions which contain substring “0”.

  1. First, we get coordinates of the left top corner of the table cell:
double x = tbl.X + cell.OffsetX;
double y = tbl.Y + cell.OffsetY;
  1. Then, we use IParagrap.GetRect() and IPortion.GetRect() methods to add frame to portions and paragraphs:
foreach (IParagraph para in cell.TextFrame.Paragraphs)
{
   if (para.Text == "")
	   continue;

   RectangleF rect = para.GetRect();

   IAutoShape shape =
	   pres.Slides[0].Shapes.AddAutoShape(ShapeType.Rectangle,
		   rect.X + (float)x, rect.Y + (float)y, rect.Width, rect.Height);

   shape.FillFormat.FillType = FillType.NoFill;
   shape.LineFormat.FillFormat.SolidFillColor.Color = Color.Yellow;
   shape.LineFormat.FillFormat.FillType = FillType.Solid;

   foreach (IPortion portion in para.Portions)
   {
	   if (portion.Text.Contains("0"))
	   {
		   rect = portion.GetRect();
		   shape =
			   pres.Slides[0].Shapes.AddAutoShape(ShapeType.Rectangle,
				   rect.X + (float)x, rect.Y + (float)y, rect.Width, rect.Height);

		   shape.FillFormat.FillType = FillType.NoFill;
	   }
   }
}
  1. Now we should add a frame to AutoShape paragraphs:
foreach (IParagraph para in autoShape.TextFrame.Paragraphs)
{
	RectangleF rect = para.GetRect();
	IAutoShape shape =
	    pres.Slides[0].Shapes.AddAutoShape(ShapeType.Rectangle,
        rect.X + autoShape.X, rect.Y + autoShape.Y, rect.Width, rect.Height);

	shape.FillFormat.FillType = FillType.NoFill;
	shape.LineFormat.FillFormat.SolidFillColor.Color = Color.Yellow;
	shape.LineFormat.FillFormat.FillType = FillType.Solid;
}

Result:
