Chart saved as Thumbnail image is very poor in quality

Hi,


We are using Aspose slide (java) to read .pptx files. When we save the charts in .pptx file as thumbnail image using the following code, the image generated is of very poor quality when compared to the image saved manually.

BufferedImage image = s.getThumbnail(ShapeThumbnailBounds.Shape, 1, 1);
ImageIO.write(image, “png”, new File(dataDirOut + slideNum+j + “.png”));

The image saved manually is crystal clear whereas the image saved through code is very poor in quality and is contrived.

PFA images and pptx file.

Is there any way to save the chart as images without losing quality. Appreciate your help in this regard.

PFA source .pptx file. This issue is highly critical for our Business users. Appreciate a quick turnaround on this.
