Hi Shubhi,


Thank you for being patient.

I would like to share with you that, The shape thumbnails are drawn on transparent background. But transparency is not supported by bmp and jpeg formats. To save a shape thumbnail to these formats you need to convert it to non-transparent image, as in the code below:

Presentation ppt = new Presentation(path + “all.pptx”);
try {
ISlide slide = ppt.getSlides().get_Item(0);
for (IShape shape : slide.getShapes())
if (shape instanceof IChart) {
BufferedImage image = shape.getThumbnail(ShapeThumbnailBounds.Appearance, 1.0f, 1.0f);

// Converting to non-transparent image with white background
// for Bmp and Jpeg formats
BufferedImage convertedImg = new BufferedImage(image.getWidth(), image.getHeight(), BufferedImage.TYPE_INT_RGB);
convertedImg.getGraphics().drawImage(image, 0, 0, Color.WHITE, null);

File outputBmpImage = new File(path + “chart_” + UUID.randomUUID() + “.bmp”);
ImageIO.write(convertedImg, “bmp”, outputBmpImage);
File outputJpegImage = new File(path + “chart_” + UUID.randomUUID() + “.jpeg”);
ImageIO.write(convertedImg, “jpeg”, outputJpegImage);
}
} catch (IOException ex) {
ex.printStackTrace();
}

I hope this will be helpful. Please share if I may help you further in this regard.
