Below is the code which i have tried to convert the booklet to A4 pdf to cut
vertically...However cropping X or Y axis and importing a page has different
result. you can take any booklet pdf and give a try.
Each Page would have two sides - one on left hand side and other on right hand
side. Booklet sample
* 2 page booklet: Type 4,1,- 1st page and 2nd page - 2,3
* 4 page booklet: Type 8,1,2,7,6,3,4,5
* 10 page booklet: Type 20,1,2,19,18,3,4,17,16,5,6,15,14,7,8,13,12,9,10,11
if front and back printed it would be 1 paper,
if front and back printed it would be 2 paper,
if front and back printed it would be 5 page,
{code}
for(int i=0; i<noOfPages; i++) {
System.out.println("Page No (PDF From Booklet): "+ (i+1));
PDDocument outdoc = new PDDocument();
PDPage page = document.getPage(i);
PDRectangle cropBox = document.getPage(i).getCropBox();
float upperRightY = cropBox.getUpperRightY();
float lowerLeftY = cropBox.getLowerLeftY();
cropBox.setLowerLeftY(upperRightY/2);
page.setCropBox(cropBox);
outdoc.importPage(page);
cropBox = page.getCropBox();
cropBox.setUpperRightY(upperRightY/2);
cropBox.setLowerLeftY(lowerLeftY/2);
page.setCropBox(cropBox);
outdoc.importPage(page);
outdoc.save(f.getParent()+File.separator+"sample_"+(i+1)+".pdf");
outdoc.close();
}
{code}
