We produce pdfs from a software system, but on occasion the pdfs may have a
blank page or two. I saw that there is java code to automatically remove
these blank pages, but I did not find any .Net code. Has anyone ever
written .Net code to remove blank pages? If so, would you guys be able to
help me? Here is the java code.
rivate int blankPdfsize = 20;
public void removeBlankPdfPages(String pdfSourceFile, String
pdfDestinationFile, boolean debug)
{
try
{
PdfReader r = new PdfReader(pdfSourceFile);
RandomAccessFileOrArray raf = new
RandomAccessFileOrArray(pdfSourceFile);
Document document = new Document(r.getPageSizeWithRotation(1));
// step 2: create a writer that listens to the document
PdfCopy writer = new PdfCopy(document, new
FileOutputStream(pdfDestinationFile));
// step 3: we open the document
document.open();
// step 4: we add content
PdfImportedPage page = null;
if (debug)
{
System.err.println("number of pages for "+pdfSourceFile+" =
"+r.getNumberOfPages());
}
for (int i=1;i<=r.getNumberOfPages();i++)
{
byte bContent [] = r.getPageContent(i,raf);
ByteArrayOutputStream bs = new ByteArrayOutputStream();
bs.write(bContent);
if (debug)
{
System.err.println("page content length of page "+i+" =
"+bs.size());
}
if (bs.size() > blankPdfsize)
{
page = writer.getImportedPage(r, i);
writer.addPage(page);
}
}
document.close();
writer.close();
raf.close();
r.close();
}
catch(Exception e)
{
System.err.println("IOException in removing blank pages from
"+pdfSourceFile+" = "+e);
}
}
