In PowerPoint presentation, text is always associated with shapes. Text can be added, modified, and extracted from auto-shapes like text box, rectangle, oval, partial circle, etc. Use the following code sample to extract text from PowerPoint presentation. //Load the PowerPoint presentation IPresentation presentation = Presentation.Open("Sample.pptx"); //Text collection to store the extracted text List<string> textCollection = new List<string>(); //Iterate each slide in a presentation foreach (ISlide slide in presentation.Slides) { //Iterate all the shapes in the slide to get the text foreach (IShape shape in slide.Shapes) { //Check the shape is table if (shape is ITable) { ITable table = shape as ITable; //Iterate all the cells in the table and gets the text foreach (IRow row in table.Rows) { foreach (ICell cell in row.Cells) { //Get the text from the cell body string text = cell.TextBody.Text; //Add the extracted text into string collection. textCollection.Add(text); } } } else { //Iterate all the paragraphs in the shape and gets the text foreach (IParagraph paragraph in shape.TextBody.Paragraphs) { foreach (ITextPart textpart in paragraph.TextParts) { //Get the text from the paragraph string text = textpart.Text; //Add the extracted text into string collection textCollection.Add(text); } } } } } //Write the text collection to a text file System.IO.File.WriteAllLines("Sample.txt", textCollection); //Dispose the presentation instance presentation.Close(); You can download the sample here.
The TreeMap leaf nodes can be colored by using the Color property specified in the DesaturationColorMapping. The RangeMinimum and RangeMaximum must be specified to determine the opacity for each leaf node. The opacity of lead nodes are in the range of From and To mentioned in DesaturationColorMapping. XAML Refer to the following online documentation link for more details on DesaturationColorMapping. http://help.syncfusion.com/UG/winrt/documents/desaturationcolormap.htm Sample Location for DesaturationColorMapping DesaturationColorMapping.zip XAML The following screenshot displays DesaturationColorMapping. Figure 1: DesaturationColorMapping
The TreeMap leaf nodes can be colored using the Color property based on its Range, From and To, and the Brush, specified using RangeBrush collection of RangeBrushColorMapping.
