Hi,
Requirement is , there is a thridparty application which reads multiple word
documents from a predefined input location and converts them in to one pdf
file and writes it to predefined output location location.
We need to read this pdf file and create a new pdf file and add page numbers
to all the pages of this pdf file.
We get an error - "Map failed" that gets printed in the output when the file
size is 200MB.
Code Snippet pasted below
public void execute(
String inputPdfName,
String outputDirName,
String outputPdfName,
BaseFont bf,
float fontSize
) throws Exception {
try {
Document document = null;
PdfReader reader = new PdfReader(inputPdfName);
int n = reader.getNumberOfPages();
PdfStamper stamp = new PdfStamper(reader, new
FileOutputStream(outputDirName + outputPdfName));
int i = 0;
PdfContentByte over;
float textSize = 0;
String strText = "";
float textBase = 0;
while (i < n) {
i++;
document = new Document(reader.getPageSizeWithRotation(i));
strText = i + "/" + n;
textSize = bf.getWidthPoint(strText, fontSize);
textBase = document.top();
over = stamp.getOverContent(i);
over.beginText();
over.setFontAndSize(bf,fontSize);
float adjust = bf.getWidthPoint("0", fontSize);
over.setTextMatrix(document.right() - textSize - adjust,
textBase);
over.showText(strText);
over.endText();
}
stamp.close();
document.close();
} catch (DocumentException de) {
System.err.println(de.getMessage());
} catch (IOException ioe) {
System.err.println(ioe.getMessage());
}
}
Does this code needs some tweaking to improve memory usage to avoid MAP
failed or OutofMemeory error????
Thanks
Saru
