Extracting Pdf to jpeg images conversion issues

Aspose.PDF Product Family

Hi,

I am facing issues in extracting pdf to jpg images

  1. In following pdf file it forms multiple copies of a image(equal to number of pages) and all the images do not get converted.
    file-sample_150kB.pdf (139.4 KB)

  2. In following pdf file there are no images but it forms a number of blank jpg images(equal to number of pages in the pdf file)programs.pdf (281.9 KB)

Here is the code I am using:
for (int pageCount = 1; pageCount <= document.getPages().size(); pageCount++)
{
Page page = page = pages.get_Item(pageCount);
XImageCollection images = images = page.getResources().getImages();
for(int imageCount = 1; imageCount <= images.size(); ++imageCount) {
XImage xImage = images.get_Item(imageCount);
zos.putNextEntry(new ZipEntry(fileNameWithOutExtension+pageCount+imageCount+".jpg")); //c
xImage.save(zos);
zos.closeEntry();
}
}

Thank you for contacting support.

For the first issue, a ticket with ID PDFNET-47304 has been logged in our issue management system for further investigation and resolution. However, for the second file, it contains several other images including inline images. You may check the same with Preflight by listing page objects or with below code snippet:

// Open document
Document pdfDocument = new Document(dataDir + "programs.pdf");
pdfDocument.Save(dataDir + "test.xml" , SaveFormat.MobiXml);

Likewise, below code snippet saves hundreds of images from this PDF document.

// Open document
Document pdfDocument = new Document(dataDir + "programs.pdf");
int counter = 0;
foreach (Page page in pdfDocument.Pages)
{
    foreach (XImage xImage in page.Resources.Images)
    {
        counter++;
        FileStream outputImage = new FileStream(dataDir + "output_" + counter + ".jpg", FileMode.Create);

        // Save output image
        xImage.Save(outputImage, System.Drawing.Imaging.ImageFormat.Jpeg);
        outputImage.Close();
    }
}
