The extraction of text is often encountered in work and study, in the previous article, has described how to extract the text in the ppt Chinese box, in this article, will explain how to use the C # code language to extract the text of SmartArt and annotations in the PPT document. Similarly, the program needs to use the spire.ppt for. NET, before writing the code, you need to install, and add reference DLL files into the project program.
1. extracting text from a SmartArt
Original file:
A SmartArt graphic is inserted in slide 2, containing text content
1 usingSpire.Presentation.Diagrams;2 usingSystem.Drawing;3 usingSystem.Text;4 usingSystem.IO;5 usingspire.presentation;6 7 namespaceextracttextfromsmartart_ppt8 {9 class ProgramTen { One Static voidMain (string[] args) A { - //Initializes an instance of the presentation class and loads the document -Presentation ppt =NewPresentation (); thePpt. LoadFromFile (@"C:\Users\Administrator\Desktop\Sample.pptx"); - //Create a new StringBuilder object -StringBuilder st =NewStringBuilder (); - //Traverse a SmartArt graphic in a document + for(inti =0; I < ppt. Slides.count; i++) - { + for(intj =0; J < ppt. Slides[i]. Shapes.count; J + +) A { at if(PPT. Slides[i]. SHAPES[J] isIsmartart) - { -Ismartart smartArt = ppt. Slides[i]. SHAPES[J] asIsmartart; - for(intK =0; K < SmartArt.Nodes.Count; k++) - { - St. Append (Smartart.nodes[k]. Textframe.text); in } - } to } + } - //writing text to a TXT document theFile.writealltext ("Result.txt", St. ToString ()); * } $ }Panax Notoginseng}
The extracted text is as follows:
2. extracting text from annotations
Original file:
on slide 1 , a comment is inserted that contains the text content
1 usingSystem;2 usingSystem.Text;3 usingspire.presentation;4 usingSystem.IO;5 6 namespaceextracttextfromcomment_ppt7 {8 class Program9 {Ten Static voidMain (string[] args) One { A //instantiates a presentation class and loads the document -Presentation ppt =NewPresentation (); -Ppt. LoadFromFile (@"C:\Users\Administrator\Desktop\comment.pptx"); the //Create a StringBuilder object -StringBuilder str =NewStringBuilder (); - //get all annotations on the first slide -Comment[] comments = ppt. slides[0]. Comments; + //Traverse Annotation Content - for(inti =0; I < comments. Length; i++) + { AStr. Append (Comments[i]. Text +"\ r \ n"); at } - //writing text to a TXT document -File.writealltext ("TextFromComment.txt", str. ToString ()); - } - } -}
The above method is to extract ppt SmartArt and annotated text in the implementation of the method for reference, I hope to help you, thank you for reading!
