RE: [PHP] Re: Can't display PNG images

Hi You will probably have to recompile gd as well. Tom At 11:33 AM 13/03/2002, Narvaez, Teresa wrote:

Thank you so much for your responses. Thanks for any response! I now the GD libraries with PNG support. However, the image is still broken.

If you do this Teresa, you should get the PHP error message, and if you give this to us it would help.

I know that wasn't much help. On another point, in my opinion, it doesn't make a whole lot of logical sense to have a die("Error text") statement in code that creates an image.. If an error does occur, it will still display the same broken image icon. However, I am not the definitive word on the matter, and if you or anyone else has a different opinion on the matter, I would be more than happy to hear it.

Hello, Background info: ---------------- I'm running

    o PHP 4.1.1 on a linux server kernel(2.2.16).
    o Using Netscape Communicator 4.75
    o Compiled and installed the gd(1.8.4) library

Problem(2 problems): -------------------- 1.- The following code won't display an image(I get an icon of some type

of

piece of paper). <?php header ("Content-type: image/png"); $im = @ImageCreate (50, 100)

      or die ("Cannot Initialize new GD image stream");

$background_color = ImageColorAllocate ($im, 255, 255, 255); $text_color = ImageColorAllocate ($im, 233, 14, 91); ImageString ($im, 1, 5, 5, "A Simple Text String", $text_color); ImagePng ($im); ?> 2.- The configure Command from phpinfo() is different than what

I actually

typed at the

    command line.  Also, phpinfo() area for GD does not show PNG or JPEG

support. why?

       from phpinfo()
       --------------
         './configure' '--with-mysql' '--with-apxs=/var/apache/bin/apxs'
         '--with-gd=/home/builder/downloads/untarred/gd-1.8.4'

'--enable-sockets'

         '--enable-calendar' '--enable-ftp' '--enable-trans-sid'
       What I typed at the command line:
       ---------------------------------
         ./configure --with-mysql --with-apxs=/var/apache/bin/apxs
          --with-gd=/home/builder/downloads/untarred/gd-1.8.4
          --with-png-dir=/usr/lib --enable-gd-native-ttf --with-ttf
          --with-jpeg-dir=/home/builder/downloads/untarred/jpeg-6b
          --with-t1lib=/home/builder/downloads/untarred/t1lib-1.3.1
          --enable-sockets --with-zlib-dir --with-xpm-dir

--enable-calenda r

          --enable-ftp --enable-trans-sid

OUTPUT from phpinfo() -----------------------

GD Support            enabled
GD Version            1.6.2 or higher
WBMP Support          enabled

I would really appretiate any ideas you could give me. Thanks in advance! -Teresa
