[mapguide-users] Re: Generate a pdf view of the current map

[ram282]

I had successfully generated pdf in this way.... 

In this, I am temporarily saving the image files and after generating the
pdf, I am deleting them. Yo should require the php file called fpdf.php,
through which u are going to generate the pdf.  

And I also changed some configuration settings in the php.ini (LOCATED AT
C:\Program Files\OSGeo\MapGuide\Web\Php\php.ini)

remove the semicolon at the start of the lines
;extension=php_curl.dll
;extension=php_gd2.dll    in the php.ini file....

 Here is the code..

<?php

$fusionMGpath = '../../layers/MapGuide/php/';
include $fusionMGpath . 'Common.php';
require($fusionMGpath . 'fpdf.php'); 


  $locale = "en";
    $mapName = "";
    $sessionId = "";
    $isTitle = "";
    $isLegend = "";
    $isArrow = "";
    $title = "";
    $scale = "";
    $centerX = "";
    $centerY = "";
    $dpi = "";
    $Server= "";
    
    $clAgent = "Fusion%20Viewer";
    $tempMapImgPath="";
    GetRequestParameters();
    $agent = GetRootVirtualFolder() . "/mapagent/mapagent.fcgi";

save the above code as some file  mappdf.php in the folder  C:\Program
Files\OSGeo\MapGuide\Web\www\fusion\widgets\Print


I will call this pdf file from print.js (widget) 

 showPdf: function() {

        var mainMap = this.getMap();

//   this.printablePdfURL  is  Fusion.getFusionURL() + widgetTag.location +
'Print/mappdf.php';

        var url = this.printablePdfURL + '?';
        var extents = mainMap.getCurrentExtents();
        var centerX = (extents.left + extents.right) / 2;
        var centerY = (extents.top + extents.bottom) / 2;
        var dpi = mainMap._nDpi;
        var scale = mainMap.getScale();
        var maps = mainMap.getAllMaps();
        url = url + 'MAPNAME=' + mainMap.getMapName();
        url = url + '&SESSION=' + maps[0].getSessionID();
        url = url + '&CENTERX=' + centerX;
        url = url + '&CENTERY=' + centerY;
        url = url + '&DPI=' + dpi;
        url = url + '&SCALE=' + scale;
        url = url + '&ISTITLE=' + (this.showTitle != '' ? '1' : '0');
        url = url + '&ISLEGEND=' + (this.showLegend ? '1' : '0');
        url = url + '&ISARROW=' + (this.showNorthArrow ? '1' : '0');
        url = url + '&SERVER=' +
Fusion.getFusionURL().split('/mapguide')[0];
        if (this.pageTitle != '') {
            url = url + '&TITLE=' + this.pageTitle;
        }

        window.open(url, 'printablepdf', '');
    }
