Page management

How to add, remove, count and manage the pages of your document. By Ludwig Zeller

Adding pages


#includepath "~/Documents/;%USERPROFILE%Documents";
#include "basiljs/bundle/basil.js";

function draw() {
    // add one page at the end of the document and jump to it
    b.addPage();
    b.text("Example 1", b.width / 2, b.height / 2, 100, 100);
}

b.go();

Removing pages


    // removes current page
    b.removePage();
    
    // fill up again...
    b.addPage();

    // removes page 1
    b.removePage(1);

Using references to pages


#includepath "~/Documents/;%USERPROFILE%Documents";
#include "basiljs/bundle/basil.js";

function draw() {

    var myPage = b.addPage();
    var myTextFrame = b.text("hello world", 20, 20, 100, 20); // add a text frame on that page
    b.page(1); // leave that page
    b.page(myTextFrame); // go to the page where this PageItem sits

    // removes myPage right away... you won't see it ever
    b.removePage(myPage);

}

b.go();

  • addPage() and page() return a reference to the new or determined page that you can store in a variable.
  • You can pass a PageItem such as a TextFrame to page() in order to jump to the page that contains the given PageItem

Populating larger documents and adding between pages


#includepath "~/Documents/;%USERPROFILE%Documents";
#include "basiljs/bundle/basil.js";

function draw() {
        
    // run this on an empty document with only one page!

    // add pages until 20
    for( var i = b.pageCount(); i < 20; i++) {        
        b.addPage();
        b.text("Example 2-" + i, b.width / 2, b.height / 2, 100, 100);
    }
    
    // set location of insertion
    b.addPage(b.AT_END); // default
    b.text("Example AT_END", b.width / 2, b.height / 2, 100, 100);
    b.addPage(b.AT_BEGINNING); 
    b.text("Example AT_BEGINNING", b.width / 2, b.height / 2, 100, 100);
      
    // adds a page before page 15
    b.page(10); // set current page
    b.addPage(b.BEFORE); // this refers to the current page
    b.text("Example BEFORE 10 becomes the new 10", b.width / 2, b.height / 2, 100, 100);

    // guess what!
    b.page(15);
    b.addPage(b.AFTER); 
    b.text("Example AFTER 15 becomes 16", b.width / 2, b.height / 2, 100, 100);

    b.println(b.pageCount());

}

b.go();

  • This example rises the page count to 20
  • You can use b.AT_END, b.AT_BEGINNING, b.BEFORE and b.AFTER to define where the new page should be inserted
