GD2/image_lib working on live website, but not on localhost (XAMPP)

[eluser]shadowmanwkp[/eluser]
Hi there, I've been scouring the internet for an answer, but I just can't seem to find one. My problem is with a controller that uses img_lib's resize function. There's an existing website I'm working on that displays the images that go through img_lib properly, but when I look at them through localhost, they show up as broken images. If I use <img> tags to point directly to the images they work absolutely fine, only the images that get go through the controller get broken.

Here's the code:

Code:

function resized() {
  $irrelevant_part_of_uri = "/images/resized/" . $this->uri->segment(3) . "/" . $this->uri->segment(4) . "/";
  $image_path = substr(uri_string(), strlen($irrelevant_part_of_uri));
  //$image_dimensions = getimagesize("public/" . $image_path);

   $config['image_library'] = 'gd2';
   $config['source_image'] = "public/" . $image_path;
   $config['create_thumb'] = FALSE;
   $config['maintain_ratio'] = TRUE;
   $config['width'] = $this->uri->segment(3);
   $config['height'] = $this->uri->segment(4);
   $config['dynamic_output'] = TRUE;
   $config['quality'] = 100;
   $this->load->library('image_lib', $config);
   $this->image_lib->resize();
}

Because the dev that made the website is gone, and I have no documentation, it took me a while to figure out the code:

- There's a controller images.php with the function resized()
- The images already exist and reside in <domain>/public/userfiles/images and its subfolders
- The image paths are pulled from a database, which I have running locally. These paths are put into <img> tags in their respective views
- I have no clue why 'public/' is concatenated in source_image, the dev might as well have put that part of the path in the database
- All images that need to be resized have the following urls <domain>/images/resized/<width><height>/actual/path/to/file.jpg
- The function looks at <width> and <height> and uses uri->segment in order to see the dimensions that need to be resized to
- Because dynamic_output is on, there's no actual folder that points to the image, but you can fool the <img> tags so you do display an image (just stick them in the folder hierarchy the src attribute specifies)
- It does not matter if I autoload image_lib, and call it through a different function (forgot the specifics...): I still get thrown an error
- According to netbeans, $image_dimensions wasn't used anywhere, so I commented it out, didn't seem to affect anything

Here's some more info using a non-existing image (if I use an existing one, the browser throws an error message because the image is broken):

Example URL:
http://<local domain>/images/resized/150/300/userfiles/images/products/asdf.jpg

Code:

echo $irrelevant_part_of_uri: /images/resized/150/300/
echo $image_path: userfiles/images/products/asdf.jpg
echo $this->image_lib->display_errors():
The path to the image is not correct.

Your server does not support the GD function required to process this type of image.

print_r($config):

Array

    [image_library] => GD2
    [source_image] => public/userfiles/images/products/asdf.jpg
    [create_thumb] =>
    [maintain_ratio] => 1
    [width] => 150
    [height] => 300
    [dynamic_output] => 1
    [quality] => 100
)

print_r(gd_info()):

Any help would be greatly appreciated!

hey, did you find the solution?

Could it be that GD Lib isn't installed in XAMPP ?

GD2 is installed with every XAMPP, the only thing you have to do in order to activate GD2 is uncomment some lines in the php.ini. In fact the phpinfo() I shared says that it is enabled and installed:

Code:

gd

GD Support  enabled
GD Version  bundled (2.1.0 compatible)

The problem still persists though, I now have put it on a separate live domain for testing where it works a-ok, it's just that either XAMPP, or codeigniter does not like running GD2 in a local environment.

but what is this referring to in your OP ?

Code:

Your server does not support the GD function required to process this type of image.

sorry, am not a XAMPP user so was just taking a stab in the dark! :-)

Make sure you also have php5 imagemagick installed, not just GD2

For some reason they do not mention this.

To me, that seems like a more generic error. Keep in mind that the image I'm using does not exist. If I did use a proper image, the browser would dump the error information into the image itself causing an error, with no way for me to read back the information I dumped.

Either I'm doing something wrong, or imagemagick refuses to work properly. I installed "ImageMagick-6.6.7-5-Q16-windows-dll.exe" on the computer and put the imagick dll in xampp's ext folder. After that I edited the php.ini to include php_imagick.dll, but it refuses to resize the image: the browser still shows dummy images. I uninstalled imagemagick and instead of choosing program files (x86)/imagemagick, I chose c:/imagemagick, but to no avail.

According to the phpinfo() at least imagick should work:

Code:

imagick

imagick module enabled
imagick module version  3.1.0
imagick classes  Imagick, ImagickDraw, ImagickPixel, ImagickPixelIterator
ImageMagick version  ImageMagick 6.6.7-5 2011-02-03 Q16 http://www.imagemagick.org
ImageMagick copyright  Copyright (C) 1999-2011 ImageMagick Studio LLC
ImageMagick release date  2011-02-03

However if I look at "environment" table of phpinfo(), it could be that it looks in the wrong folder, because the environment table contains both the old and the new path to imagemagick:

Code:

Environment

Path  C:\ImageMagick-6.6.7-Q16;C:\Program Files (x86)\ImageMagick-6.6.7-Q16;

Note: the imagemagick folder in program files does not exist anymore.

Question? What OS are you running and if using xampp where did you install it to?

Ok, I see that you are running xampp. Xampp needs to be installed in the c:\ root not under Program Files (x86)

Xampp has problems if it is not installed in the c:\ root on Windows OS.

c:\xampp

Thats where it should be if your running on Windows, also if you place it in the root like above I can explain to you how to setup the Windows environment variables for it.

Already installed to c:\xampp, I've heard many problems about running it from x86 program files, especially on x64 vista systems and newer due to UAC. The operating system is windows 8 pro 64-bit (6.2 build 9200).

I don't know if this helps you... https://community.apachefriends.org/f/vi...17&t=53258 I think they are talking about Xampp 1.8.3

Setting Windows Environment varables:

Code:

1) Windows Control Panel
2) System and Security
3) On the left side click on Advanced system settings
4) On the bottom you will see a button Environment Variables click on that
5) In the bottom system variables edit the path, go to the end and add a ; semi-colon if it is not there then
    add c:\xammp;c:\xampp\php;

6) you can add other paths also, like for composer and Git.

If you still cannot get it working I have an image library here that someone on here wrote that uses the CI Image_lib
