C # extract PPT text and picture implementation scheme

In a text -to-text document, we can extract textual information or images from the document as needed,C #code can be extractedWordand thePDFfiles in the text and pictures, then the same, we can also extractPPTthe text and pictures in the slide. This document will describe how to use theC #to implement extractionPPTthe manipulation of text and pictures. The first is the need to install componentsspire.presentation, and then add a referenceDLLfile into the project. The following are the main code steps.

1. extracting text

Step One: creating a presentation instance and loading the document

Presentation Presentation = newpresentation (@ "C:\Users\Administrator\Desktop\sample.pptx", fileformat.pptx2010);

Step Two: Create a StringBuilder object

StringBuilder sb = Newstringbuilder ();

Step three: Traverse the slides and the graphics on the slide to extract the text content

 foreach  (islide slide in presentation. Slides)             {                 foreach  (ishape shape in  slide. Shapes)                 {                      if  (Shape isiautoshape)                      {                         foreach  ( textparagraph tp in  (Shape asiautoshape). textframe.paragraphs)                          {                              SB. Append (TP. Text +environment.newline);                         }                     }                 }             }

Step four: Write TXT document

File.writealltext ("Target.txt", sb.) ToString ()); Process.Start ("Target.txt");

2. Extract pictures

There are two cases of extracting pictures here, one is to extract all the pictures in the entire document, and the other is to extract only the pictures from a particular slide in the document.

2.1 extract All pictures

Step One: Initialize an instance of the presentation class and load the document

Presentation ppt = newpresentation ();pp T. LoadFromFile (@ "C:\Users\Administrator\Desktop\sample.pptx");

Step two: Traverse the picture in the document, extract the picture and save

for (int i = 0; I <ppt. Images.count; i++) {image image = ppt. Images[i].     Image; Image. Save (String. Format (@ ": \.. \images{0}.png ", i)); }

The extracted picture has been saved to the project folder

2.2. extracting pictures from a specific slide

Step One: Create an instance of the presentation class and load the document

Presentation PPT = NewPresentation (); Ppt. LoadFromFile (@ "C:\Users\Administrator\Desktop\sample.pptx");

Step two: Get the third slide, extract and save the picture

int i = 0;foreach (IShape s inppt.slides[2].       Shapes) {if (s isslidepicture) {slidepicture PS = s asslidepicture; Ps. PictureFill.Picture.EmbedImage.Image.Save (String.        Format ("{0}.png", i));    i++;        } if (s ispictureshape) {Pictureshape PS = s aspictureshape; Ps. EmbedImage.Image.Save (String.        Format ("{0}.png", i));    i++; }}

The picture from the third slide you extracted is saved to the specified location

The above shows how to extract text and pictures, the steps are simple and practical, I hope to help you, thank you for reading!
