Hi Bharathkumar,
Thanks for contacting support.
I have tested the scenario using Aspose.Pdf for Java 9.0.0 in Eclipse Juno project running over Windows 7(x64) with JDK 1.7 and I am unable to notice any problem. The PDF pages are properly being converted to PNG and JPEG images. For your reference, I have also attached the some of the images images generated over my end. Can you please share some further details which can help us in identifying these problems. We are sorry for your inconvenience.
[Java]
//open
document<o:p></o:p>
com.aspose.pdf.Document
pdfDocument = new com.aspose.pdf.Document("c:/pdftest/AISB08.pdf");
//
loop through all the pages of PDF file
for (int pageCount = 1; pageCount <=
pdfDocument.getPages().size(); pageCount++)
{
//
create stream object to save the output image
java.io.OutputStream imageStream = new java.io.FileOutputStream("c:/pdftest/AISB08_Converted_Image" + pageCount + ".jpg");
//create
Resolution object
com.aspose.pdf.devices.Resolution
resolution = new com.aspose.pdf.devices.Resolution(300);
//create
JpegDevice object where second argument indicates the quality of resultant
image
com.aspose.pdf.devices.JpegDevice
jpegDevice = new com.aspose.pdf.devices.JpegDevice(resolution, 100);
//convert
a particular page and save the image to stream
jpegDevice.process(pdfDocument.getPages().get_Item(pageCount),
imageStream);
//close
the stream
imageStream.close();
}
