Re: Zend PDF and the RPG Experiment -- WEB400

This is very cool (extremely cool actually!) I LOVE PHP! It's soooo much
easier to almost everything with PHP than it is with RPG.

But...this doesn't solve Aaron's problem of capturing the HTML form itself
and turning that into a PDF. At least not as I understood what he was
asking for.

This instead takes a separate instance of the data and rebuilds it into a
PDF, right?

Or maybe that's good enough for Aaron's needs in this case.

The one benefit to the approach I offered yesterday is that it captures the
users browser session exactly as is and creates an image of that which can
then be used as is or converted to a PDF or whatever. The data is only
touched once. With very little code. In fact, the entire code is a little
bit of JavaScript and a very small java program:

<HTML>

<HEAD>

<TITLE>Screen Capture Demo</TITLE>

<SCRIPT LANGUAGE="JAVASCRIPT">




function getScreenCaptureDimensions()
{
window.status = "Capturing Image of Document...please stand by...";
var sl = window.screenLeft;
var cw = document.body.clientWidth;
var ch = document.body.clientHeight;
var imagename = 'YourImage';
var st = window.screenTop;
st = st + 2;
ch = ch - 1;
sl = sl + 3;
var DimensionParms = ('"' +
sl + '" "' +
st + '" "' +
cw + '" "' +
ch + '" "' +
imagename + '"');

capturescreen(DimensionParms);
}




function capturescreen(inParms)
{
var oShell = new ActiveXObject("Shell.Application");
oShell.ShellExecute ("C:\\SCAP1.lnk", inParms, "0", "open", "0");
}

</SCRIPT>
</HEAD>
<BODY>
<FORM>

<CENTER>

Click on the button below to capture the screen to a JPEG file. <br>
A new image file named "YourImage.JPEG" will be created in the root
directory.<br>

<br><br>
<input type="Button" name="Capture" value="Capture Screen as JPEG"
onClick="getScreenCaptureDimensions()" />
</center>

Aaron,

I am starting a new thread.

I was hoping someone would open the door for PHP. I would recommend
Zend Server for IBM i Community Edition. (GA, VERY soon, beta available
at link below) This is the no charge runtime for PHP and includes Zend
Framework. Why do I mention ZF? Simply because there is support for
Zend_PDF which supports a template approach to PDF generation. I am
working with some folks to put an nice example here. See this link for
the documentation on Zend_PDF for more details:
http://framework.zend.com/manual/en/zend.pdf.html

Once you start with PHP, you may never go back to Java ;-)

Of course, you can use FPDF in this environment too.

I am not aware of another solution to deliver PHP to IBM i short of Rob
Ward. But all I see of his previous site is a blog now. If you hear of
one I would like to know.

Below is a really BASIC example of Zend_PDF in action without a
template. It's not gl;amorous but I think you get the idea. There are
quite a few interesting components in this little hunk of code. In
addition to the Zend_PDF example is an example of how you can use the
library list in PHP, using PHP functions, DB2 error trapping, DB2 Fetch
of a record into an associative array (one of my favorites) and the use
of the root file system to drop the PDF. Once it is there you can do
with it what you want like attach it to an email, archive, etc.

Why buy tools when you can get this for free?
