> Senario 2.
> After loading pdf through PDFRenderer(pdf), We are trying to take the first page and convert that into preview image, so we are calling "pdfRenderer.renderImageWithDPI(0, 300, ImageType.RGB)", it takes more time to return the bufferimage.
> after we called ImageIOUtil.writeImage(bufferedImage, fileName, 175) tooks more time to save it to local and the size of the image is very huge.
> for example.
> total size of the pdf - 2.7 mb
> first page image size - 14 MB.
