Hi
We are licenced version of aspose.pdf 4.5. We are running following code using either DOM or SimplePDF at a time.
And configuring it by static variables. Boolean withRowFormatting is set to true if we only need row formatting and false if we only need cell formatting.
Problem facing.
1. For large number of selection say 2000 rows and 255 columns, getting java out of bound exception.. also changed the JVM size to 2gb
2. In case of simple pdf, if we increase the number of columns more than 255, whatever the row count is ,
the downloaded pdf file shows 0 kb
Could you suggest , why PDF creation is consuming large amoumt JVM memory just to generate a PDF file of few Mbs
Here is snippet code, and its consuming large amount of memory to generate PDF for the both the cases
public class Test {
static int ROW = 2000; // Number of ROWS
static int COL = 300;// Number of COLUMNS
static Boolean withRowFormatting = true;
public static void main(final String[] args) throws Exception
{
SimplePDFAspose(); //PDF
DOMPDFAspose(); // Document
}
public static void DOMPDFAspose() throws Exception
