[maplab-users] MapServer Error in msSaveImage()

[Gonzalo Valdés]

Hi, I have configure Map Server last week and takes me a while to understand
the map file structure (I'm new at GIS as well) but I put it to work. So,
when i find out MapLab I want to tray it a.s.p..  
I'm working in a Linux RedHat 7.2 machine, and i had apache copiled from the
source whith php 4.2.1 (static) so I recompile my PHP source whith the
options: 
----------------------------------------------------------------------------
------- 
 './configure' '--with-system-regex' '--with-gd' '--enable-shared'
'--with-ttf' '--enable-gd-native-ttf' '--enable-force-cgi-redirect'
'--enable-dbase' '--with-xml' '--with-mysql=/usr/local/mysql' 
----------------------------------------------------------------------------
------- 
Install the CGI executable and get  reconfigured my httpd.conf so PHP is now
run  as a CGI. 
 
Then I recompiled my  mapserver source and install the php_mapscrip.so and
every thing looks ok. 
whith the mapscript part when I run: phpinfo_mapscript.phtml  
----------------------------------------------------------------------------
-------------           
                                           MapScript 
 
MapScript Version ($Revision: 1.104.2.1 $ $Date: 2002/06/03 14:19:53 $) 
MapServer version 3.6.1 OUTPUT=PNG OUTPUT=JPEG OUTPUT=WBMP SUPPORTS=TTF
INPUT=TIFF INPUT=EPPL7 INPUT=JPEG INPUT=SHAPEFILE 
----------------------------------------------------------------------------
------------ 
 
Then I install MapLab and try to configure it from the index.phtml but at
ferst it sed somthin like "This is a only read file can not be modify......"

So I chance the permissions on all files on the config directory so make
them writable as well as the projects and data directory. The tmp directory
is 777 so I didn't change anything. 
Then the interface to configure MapLab seems ok, (showing enviromet
variables proposed for seting) but it didn't write the changes. (I don't
know if any body had this same problem. I'm using:  Mozilla/5.0 (X11; U;
Linux i686; en-US; rv:0.9.9) Gecko/20020513, but after I tray from IE and
work find) 
 
So I edit the files manually and then thins looks like ok, I can get into
the MapEdit and load a map file, but when i tray to make a preview, I get
the masage:

I notice a .gif formatin this (and my image_type is PNG) so I went to line
374 and find: 
----------------------------------------------------------------------------
---- 
//if (!session_is_registered("gszImageType")) 
    $urlMainMap = $imgMainMap->saveWebImage(MS_GIF, 0, 0, -1); 
//else 
//    eval("\$urlMainMap = \$imgMainMap->saveWebImage(MS_".$gszImageType.",
0, 0, -1);");

So I tray to uncoment this lines but still get errors: 
----------------------------------------------------------------------------

----------------------------------------------------------------------------

So I coment this lines again, and decide to ask for help. 
 
I thougth it may be some permissions promblems, but I'm using the same tmp
directory than my mapserver script and it works. 
 
I will thanks any help, (...........and please......... forgive my Inglish)
