Description

startY	0	The y cooridinate of a reference point to align with the top-left corner the pattern.

The web page then includes an <IMG> tag as follows:

When the browser reads the HTML web page and sees the <IMG> tag, it will load the image using myimage.php from another HTTP connection.

Note that the above assumes the myimage.php is located in the same directory as your web page. If it is in a different directory, you would need to modify the path in the <IMG> tag.

For reference, the following is the source code of myimage.php.

<?php session_start(); print $HTTP_SESSION_VARS[$HTTP_GET_VARS["img"]]; ?>

Arguments

Argument	Default	Description
name	(Mandatory)	The name of the session variable used to store the chart image. If there are multiple chart images in the same web page, each image must use a different name.
imageFormat	PNG	A constant representing the format of the image. Must be one of the pre-defined constants PNG, JPG, GIF, BMP or WMP.

Return Value

A string representing the query parameters for retrieving the image using the myimage.php utility.
