Extracting Images from Presentation in C# Throws ArgumentException

Aspose.Slides Product Family
,

I have a demo1.pptx file, and when I extracted the image on the 12th slide, an ArgumentException was thrown.
I copied this file as demo2.pptx, then deleted all the slides after the 12th slide, and then extracted
the same image, and it worked normally.

The Demo File

ExtraImageError.zip (700.1 KB)

Sample Code

void Main()
{
	var file1 = @"C:\Users\54390\Downloads\demo1.pptx";
	var file2 = @"C:\Users\54390\Downloads\demo2.pptx";
	
	//demo1.pptx
	var ppt = new Aspose.Slides.Presentation(file1);
	var slide = ppt.Slides[11];
	ExtraImage(slide);

	//demo2.pptx
	ppt = new Aspose.Slides.Presentation(file2);
    slide = ppt.Slides[11];
	ExtraImage(slide);
}

private void ExtraImage(ISlide slide)
{
	for (int i = slide.Shapes.Count - 1; i >= 0; i--)
	{
		var shape = slide.Shapes[i];

		if (shape is Aspose.Slides.PictureFrame)
		{
			var pf = shape as IPictureFrame;
			pf.PictureFormat.Picture.Image.Dump();
		}
	}
}

@sullivan,

@sullivan,

In Aspose.Slides for .NET, the IPPImage interface does not contain the Dump method. It looks like the issue is not related to Aspose.Slides. Please check your code carefully.

Sorry, dump is only supported in LINQPad, You can use Console.WriteLine() instead.

Console.WriteLine(pf.PictureFormat.Picture.Image);
