[PHP] Re: GD Library and outputing image
Ross escreveu:
$image = imagecreatefromjpeg($img_url);
$image in this case, is the Image Identifier, and returns something like
, Resource id #NUMBER ( Resourse id allocation process, for the generic
imagecreate... ).
if ($image === false) { die ('Unable to open image'); }
// Get original width and height
echo $width = imagesx($image);
echo $height = imagesy($image);
// New width and height
$new_width = 200;
$new_height = 150;
// Resample
$image_resized = imagecreatetruecolor($new_width, $new_height);
$image_resized is another Image Identifier
imagecopyresampled($image_resized, $image, 0, 0, 0, 0, $new_width,
$new_height, $width, $height);
The imagecopyressampled() returns a boolean value [ TRUE(1) or FALSE(0)].
This value can be used to test the function success.
A) If you haven't no problem with readers, you must use:
> // Display resized image
> header('Content-type: image/jpeg');
> imagejpeg($image_resized);
imagedestroy($image);
imagedestroy($image_resized);
So, in this case you have 2 Image Identifiers, to be destroyd at the
end, to freely the processes.
imagedestroy($image);
imagedestroy($image_resized);
B) However, if you have problems with header, you must use:
imagejpeg ($image_resized, "image.jpg");
echo '';
imagedestroy($image);
imagedestroy($image_resized);
instead of
>
> // Display resized image
> header('Content-type: image/jpeg');
> imagejpeg($image_resized);
imagedestroy($image);
imagedestroy($image_resized);
die();
This is not allowed here.

[PHP] Re: GD library images not displaying
Found this in the PHP manual,
To enable GD-support configure PHP --with-gd[=DIR], where DIR is the GD
base install directory. To use the recommended bundled version of the GD
library (which was first bundled in PHP 4.3.0), use the configure option
--with-gd. GD library requires libpng and libjpeg to compile.
In Windows, you'll include the GD2 DLL php_gd2.dll as an extension in
php.ini. The GD1 DLL php_gd.dll was removed in PHP 4.3.2. Also note that
the preferred truecolor image functions, such as imagecreatetruecolor(),
require GD2.
So, why not try upgrade your PHP version.

Hi,
I am running Apache 2.0 with PHP 4.2.11 on Windows XP.
I installed php_gd2.dll by uncommenting extension=php_gd2.dll and making sure
that the file was in my extension_dir.
I restarted Apache and didn't get an error, so assumed it was working.
When I run my example code:
$im = imagecreatetruecolor (300, 200);
$black = imagecolorallocate ($im, 0, 0, 0);
$white = imagecolorallocate ($im, 255, 255, 255);
imagefilledrectangle($im,0,0,399,99,$white);
imagerectangle($im,20,20,250,190,$black);
header ("Content-type: image/png");
imagepng ($im);
?>
I get the following error:
Fatal error: Call to undefined function: imagecreatetruecolor() in
imagetest.php on line 2
This code works on other servers, so where have I gone wrong in my installation
of GD?
Thanks in advance,
Ross

Well one way to base your decision on salient facts is to find out what has changed between the 4.2.2 & 4.3.6 (and the intervening versions) by reading the changelogs. Then decide whether the bug fixes and improvements are worth your while to upgrade to. > I'm totally new at installing apps via shell...if anyone is interested in > doing it for a small fee please let me know! If you're using a pre-installed dedicated server then it's more than likely it has a version of RedHat on it. You may be lucky and be able to upgrade PHP via RPM. But AFAIK RedHat has never (or hardly ever) provided PHP upgrades. -- Jason Wong -> Gremlins Associates -> www.gremlins.biz Open Source Software Systems Integrators * Web Design & Hosting * Internet & Intranet Applications Development * -- Search the list archives before you post http://marc.theaimsgroup.com/?l=php-general -- /* Windows 99 has been released!

That was not what was said nor implied in my reply. Basically upgrading the GD lib used by PHP needs root privileges.

[PHP] RE: GD Library Upgrade
Any thoughts on this? I'm working with a host on a Linux box with PHP 4.2.2. The version of GD Library they have is 1.8.4. I was uploading some pictures using a script that leveraged GD Library 2+. Using the php version with the newer GD library seemed to produce a better quality image. I have two questions: 1 - Can a newer version of GD Library (1.8.4 vs 2+) make a difference in image quality? 2 - I'd like to upgrade the Linux box that has PHP 4.2.2 and GD Library 1.8.4 to the most recent version. Is this easy? Any guidance? Do I need a patch? PS - I've been working off of this site: http://www.boutell.com/gd but wanted to bounce this around with some experts first.

[PHP] Re: gd-library ...
Hi Marcel, I did struggle with the same prop a while ago. It's quit easy. Get yourself php4.1.2 . This version has the gd library included. after installing uncomment the libgd module line in php.ini. Look out for the different versions. There might be one line for the old 1.8x library. save it and restart your webserver. Thats it.
