node-demo produces 2 blank pages

[dlcurry]

Using latest pdf.js - the one with drawLine...
With node.js v0.4.12, which might have something to do with it, the demo produces 2 blank pages; no text or graphics. Select All, copy, paste into a text doc pastes nothing. testFile57.pdf in the repo and download displays properly, select/copy/paste pastes the text into a text editor. Ubuntu Natty 11.04.

I note that in the repo/download file, the node version is v0.3.0-pre.

There are differences between the files:
testFile57:
%PDF-1.3

BT /F1 16.00 Tf ET
BT 56.69 785.20 Td (hello, I am PDF.) Tj ET
BT 56.69 756.85 Td (i was created using node.js version: v0.3.0-pre) Tj ET
BT 56.69 728.50 Td (i can also be created from the browser) Tj ET

endstream
endobj

testFile44 (mine):
%PDF-1.3

Similar block a bit later on - also has 'undefined'.

Update: I was able to get it to work:

1. node-demo.js:
   var doc = new pdf();
   doc.setFont(1); //<<<< added to make sure fonts[] had 1 font
   doc.text(20, 20, 'hello, I am PDF.');
   doc.text(20, 30, 'i was created using node.js version: ' + process.version);
   doc.text(20, 40, 'i can also be created from the browser');
2. pdf.js:
   var _addPage = function() {
   beginPage();
   // Set line width
   out(sprintf('%.2f w', (lineWidth * k)));

// 16 is the font size
pageFontSize = fontSize;
pageFont = font;
//DLC-->>>>>delete out('BT ' + fonts[font] + ' ' + parseInt(fontSize) + '.00 Tf ET');    
//fonts[] is undefined at this point when called by _addPage();

}

Alternately, rename setFont: function... to var _setFont = function... and move the function up where _addPage() is. Then create
setFont: function(f){
_setFont(f);
},
in its place. Then, where _addPage() is called to automatically create the first page, FIRST call
_setFont(1);

This change removes the need for node-demo.js to have an initializing call to setFont.
