now the problem is that I can't install pear packages.
The mistake is pear/Image_Color requires PHP extension "gd".
As I correctly undertstood I need to have this gd library in my ext directory , but again GNOPE doesn't include it.
What to do?
Could you please help me?
Best regards, |

| You need to load it in your php.ini. There should be lines around "extension=somefile.dll" |

Yes,I know
I did it (I have php_gd2.dll in ext directory),installed Image_Graph and Image_Canvas and Image_Color,
but when I'm trying to execute the following script
| Code: |
<?php
/**
* Using Image_Graph to create a chart and displaying it directly
* in a GtkImage widget, getting it to there with the
* GdkPixbuf::new_from_gd() method.
*
* The Image_Graph code is a slightly modified version of the
* simple.php example.
*
* You need Image_Graph version 0.7.3 or higher (0.7.2 doesn't
* support the required "none" output switch)
*/
include 'lib/pear/Image/Graph.php';
//we want to use the gd library
$Graph = Image_Graph::factory('graph', array(array('width' => 400, 'height' => 300, 'canvas' => 'gd')));
//prepare the chart
$Plotarea = $Graph->addNew('plotarea');
$Dataset = Image_Graph::factory('dataset');
$Dataset->addPoint('Denmark', 10);
$Dataset->addPoint('Norway', 3);
$Dataset->addPoint('Sweden', 8);
$Dataset->addPoint('Finland', 5);
$Plot = $Plotarea->addNew('bar', $Dataset);
$Plot->setLineColor('blue@0.2');
//This is the key: Don't output anything, just finish it
$Graph->done(array('output' => 'none'));
//get the gd object
$canvas = $Graph->_getCanvas();
$gd = $canvas->_canvas;
//Create GdkPixbuf from the GD object
$pixbuf = GdkPixbuf::new_from_gd($gd);
//Display the pixbuf by using a GtkImage widget
$wnd = new GtkWindow();
$wnd->connect_simple('destroy', array('Gtk', 'main_quit'));
$wnd->add(GtkImage::new_from_pixbuf($pixbuf));
$wnd->show_all();
Gtk::main();
?>

I have 3 short sound warning, a lot of ASCII symbols and the following error message:
Fatal error:PHP-GTK was not compiled against PHP with bundled GD library in line 37

That is a bug in PHP-Gtk and should be fixed in the latest sources.
So you have two possibilities:
- Compile your own version of php-gtk
- Wait for a new release which fixes this and save the chart into a file and display it from the file in the meantime. |
