PDF to TIFF conversion performance

The java conversion seems far slower than the Dotnet offering. This sample file took 31 seconds with the java Aspose.PDF while the Dotnet Aspose.PDF only took 231 milliseconds.

I just downloaded the latest Aspose.Total for java and am using aspose-pdf-9.7.0-jdk16.jar.

Maybe I’m doing something wrong?

This is on a Windows 7 64bit workstation. Here’s my java code.

public static void main(String[] args) throws FileNotFoundException {
long tStart = System.currentTimeMillis();
// Open document
com.aspose.pdf.Document pdfDocument = new com.aspose.pdf.Document(“C:\Test\PDF\test.pdf”);
// Create stream object to save the output image
java.io.OutputStream imageStream = new java.io.FileOutputStream(“C:\Test\PDF\test.tiff”);

TiffSettings tiffSettings = new TiffSettings();

// Create Resolution object
com.aspose.pdf.devices.Resolution resolution = new com.aspose.pdf.devices.Resolution(200);
// Create TiffDevice object with particular resolution
com.aspose.pdf.devices.TiffDevice tiffDevice = new com.aspose.pdf.devices.TiffDevice(resolution, tiffSettings);
// Convert a particular page (Page 1) and save the image to stream
tiffDevice.process(pdfDocument,1,4, imageStream);

// Close the stream
try {
} catch (IOException e) {
long tEnd = System.currentTimeMillis();
long tDelta = tEnd - tStart;
double elapsedSeconds = tDelta;
