Convert a pdf page to image. text can't be seen

Aspose.PDF Product Family
1

I used Aspose.PDF to change a PDF page to jpg file. But the result is that the text can’t be seen.


what is the problem.

I did as your demo code below:

Document pdfDocument = new Document(“input.pdf”);

for (int pageCount = 1; pageCount <= pdfDocument.Pages.Count; pageCount++)

{

using (FileStream imageStream = new FileStream("image" +

pageCount + ".jpg", FileMode.Create))

{

//create JPEG device with specified attributes

//Width, Height, Resolution, Quality

//Quality [0-100], 100 is Maximum

//create Resolution object

Resolution resolution = new Resolution(300);

//JpegDevice jpegDevice = new JpegDevice(500, 700, resolution,

100);

JpegDevice jpegDevice = new JpegDevice(resolution, 100);

//convert a particular page and save the image to stream

jpegDevice.Process(pdfDocument.Pages[pageCount], imageStream);

//close stream

imageStream.Close();

}

}


the pdf is in attachments.

Hope to hear from you soon
