如何使用Aspose.Slides提取幻灯片中的图像

Posted 2023-04-27

参考技术A String path = @"..\..\..\";

//Accessing the presentation
PresentationEx pres = new PresentationEx(path+"demo.pptx");
ImageEx img = null;
int slideIndex = 0;
for (int i = 0; i < pres.Slides.Count; i++)

slideIndex++;
//Accessing the first slide
SlideEx sl = pres.Slides[i];
System.Drawing.Imaging.ImageFormat Format = System.Drawing.Imaging.ImageFormat.Jpeg;
for (int j = 0; j < sl.Shapes.Count; j++)

// Accessing the shape with picture
Aspose.Slides.Pptx.ShapeEx sh = sl.Shapes[j];

if (sh is AutoShapeEx)

AutoShapeEx ashp = (AutoShapeEx)sh;
if (ashp.FillFormat.FillType == FillTypeEx.Picture)

img = ashp.FillFormat.PictureFillFormat.Picture.Image;




else if (sh is PictureFrameEx)

PictureFrameEx pf = (PictureFrameEx)sh;
if (pf.FillFormat.FillType == FillTypeEx.Picture)

img = pf.PictureFormat.Picture.Image;


String ImageType = img.ContentType;
ImageType = ImageType.Remove(0, ImageType.IndexOf("/") + 1);

//
//Setting the desired picture format
switch (ImageType)

case "jpeg":
Format = System.Drawing.Imaging.ImageFormat.Jpeg;
break;

case "emf":
Format = System.Drawing.Imaging.ImageFormat.Emf;
break;

case "bmp":
Format = System.Drawing.Imaging.ImageFormat.Bmp;
break;

case "png":
Format = System.Drawing.Imaging.ImageFormat.Png;
break;

case "wmf":
Format = System.Drawing.Imaging.ImageFormat.Wmf;
break;

case "gif":
Format = System.Drawing.Imaging.ImageFormat.Gif;
break;

//
String ImagePath = path+"Image_";
img.Image.Save(ImagePath + "Slide_" + slideIndex.ToString() + "." + ImageType, Format);
