Discovered the following problem with aspose.slides. I have a presentation with a picture in the background. When I convert the slide in the image with slide.getThumbnail(), the background image is cut off. In version 2.9.6 it works, but since 3.0.0 the problem occurred. Can you help solve it. The presentation is attached.
I have observed the image shared by you. Can you please try using Aspose.Slides for Java 6.7.1 on your end and if there is still an issue then please share your feedback with us.
I have worked with the presentation file shared by you using following sample code by referencing Aspose.Slides for Java 6.7.1 on my end. I have not been able to reproduce the issue on my end in Windows Environment. Can you please try using the following sample code in your environment. If there is still an issue then please share the complete environment details with us where by you are reproducing the issue along with JDK version.
public static void GenThumbnail()
{
String path=“D:/Aspose Data/”;
//Instantiate a Presentation object that represents a PPT file
Presentation pres = new Presentation(path+“pres.ppt”);
//Accessing a slide using its slide position
Slide slide = pres.getSlideByPosition(1);
BufferedImage imgq = slide.getThumbnail(2f, 2f);
try {
ImageIO.write(imgq, “JPEG”, new java.io.File(path+"\Slides\Slide_"+Integer.toString(i)+".jpeg"));
Your code works perfectly. When I set my parameters slide.getThumbnail (new Dimension (999, 749)), the error appeared again. It is interesting that slide.getThumbnail (new Dimension (1000, 750)) works correctly.
I have worked over the custom dimensions shared by you and have been able to reproduce the issue specified.
