<br>
The function cannot paste the map image into the canvas (which elements
are also generated by the widget: neat line, title, coordinates,
etc...).<br>
return $o_img_canvas; returns the canvas without map (empty, white map).<br>
return $o_img_map; returns the map without canvas elements.<br>
Unluckily it doesn't display error message at all. I've tried with
several types of GD and PHP (stable, svn, etc...) but I think it's a
php_mapscript.so problem, and thus a Mapscript bug, because the
pasteImage() function is definied there

Yesterday I've tried with the latest development version of Mapscript,
but still no success. :(<br>

What is not working in this function?
<br>
Does it throw you an error or simply return false?
<br>
I this function is not working, that's really a sign that PHP and GD
are not compiled correctly or not liked correctly together. When you
recompiled PHP, did you recompile GD too?

I've finally found where the problem is located at. In the preview.php
(around the 511th row), there is paste image function.
<br>
<br>
// paste the map onto the canvas original
<br>
$o_img_canvas->pasteImage( $o_img_map, -1, $n_pix_whitespace_left,
$n_pix_whitespace_top);
<br>
<br>
This is the function what doen't work correctly because if I change
(around the 518th row) the
<br>
<br>
return $o_img_canvas;
<br>
<br>
to
<br>
<br>
return $o_img_map;
<br>
<br>
it displays the map. Although it doesn't have frame, title, coordinates
in the corners it's better than the empty white map box.
<br>
<br>
I've found this around the 679th row:
<br>
<br>
//TODO: fix me when pasteImage is fixed (bug 463)
<br>
<br>
Do anyone know where is this bug report located at or how to solve it?
<br>
<br>
Thanks in advance,

Then it's probaly something with your installation. If you don't have
any error message appearing and the map works fine outside of the
widget it means you'll need to do some debugging. In the widget file
preview.php, You can place a bunch of echo in hte function render image
to see if it crash somewhere maybe...

Thanks for the fast answer. I've tried this, and it works perfectly
(draws the map), so I'm totally confused, because the widget doesn't
display the map content at all...
<br>
<br>
Any other idea?
<br>

If you got no error in any logfile and you think your PHP/MapScript
installation is correct you should probably try your session mapfile
with a simple php script.
<br>
<br>
To get your session mapfile, search in the directory where the session
are stored for your SID. In there you will have mapfiles. Take the last
one and try it with the following code.

<br>
<br>
<?php
<br>
<br>
// define variables
<br>
define( "MAPFILE", "gmap75.map" );
<br>
<br>
if (!extension_loaded("MapScript"))
<br>
{
<br>
dl("php_mapscript_40." . PHP_SHLIB_SUFFIX);
<br>
}
<br>
<br>
// open map
<br>
$oMap = ms_newMapObj( MAPFILE, dirname( MAPFILE ) );
<br>
<br>
$oMap->selectoutputformat("png");
<br>
// draw map
<br>
$oImage = $oMap->draw();
<br>
<br>
// set header
<br>
header("Content-type: image/png");
<br>
<br>
// output map
<br>
$url = $oImage->saveImage("");
<br>
<br>
?>
