image_lib problems

[eluser]evilgeoff[/eluser]
I'm sure some of this if my fault but I've had nothing but problems with CI so far. I love the idea of the framework and the ease of installation but it seems like it's one thing after another. Again a lot of this could be what this does based on my needs and they don't jive but I'm still a little frustrated.

Currently the image_lib doesn't work.

I've tried everything I've found on this site.

I get this error: <p>Your server does not support the GD function required to process this type of image.</p><p>Your server does not support the GD function required to process this type of image.</p>

I've installed gd it shows up in phpinfo().
I've checked the permissions of the image folder that's fine.
I checked to make it was installed at all.

I've set it to initialize the library's $config.
$config['image_library'] = 'GD2';
$config['source_image'] = $path;
$config['create_thumb'] = TRUE;
$config['maintain_ratio'] = TRUE;
$config['width'] = 80;
$config['height'] = 80;
$config['new_image'] = $path.'/new/'.$image.'.jpg';
$this->load->library('image_lib');
$this->image_lib->initialize($config);
$this->image_lib->resize();
if ( ! $this->image_lib->resize())
{
$this->firephp->log($this->image_lib->display_errors());
}
$this->image_lib->clear();

I've tried everything and still nothing. At this point I would just drop this framework and move as I have deadlines, but I'm too far into the project to turn around. I'm sure this is my fault somehow but I just need results at this point before I get fired. Serious about the last part.

this may be a silly question but.... have you tried rebooting it?

I know when I was first playing around with apache/php/mysql I would always forget to restart the apache server.

Are there any other error messages? Also, check your log files.

[eluser]evilgeoff[/eluser]
That's not dumb at all. Always a good thing to try. I'll take a look at the logfile. Thanks.

One more thing to mention if this matters. I'm on lighttpd.

What is the format of the image you're using? Make sure it's a gif, jpg, or png. Have you tried multiple images or just the same one?

I'm not the biggest fan of CI's image library. I've used http://wideimage.sourceforge.net/wiki/MainPage before. It might be worth trying it also to see if you get different results.

[eluser]evilgeoff[/eluser]
Just a jpg. I was doing them in a loop but I've since set it up to do just one file and same results.

I'll try that out.

I am not getting the gd error as often now I'm getting a read/write error but everything is writeable and readable.

I'll look into wideimage. I wonder how hard it would be to add to CI. If I had time I'd try, maybe this weekend I'll give it a shot and post my results if I have time.

maybe ..
is your PHP safe mode ON or off ??

One thing you could do is take CodeIgniter out of the equation and try running the function directly and see what you get.

[eluser]evilgeoff[/eluser]
I would love to say that something you guys said helped or that I figured this out or anything like that but literally it worked all of the sudden. I really do appreciate your help and I'll start to use this forum more often instead of getting frustrated by weird behavior.

I do know that it will not work at all unless I use this $this->image_lib->initialize($config); that is the only thing I've found that HAS to be there for this to function now. I literally don't know why this started working. Again thank you all though.

I use CI 1.7.2, develop on a Mac Leopard using MAMP. After a few hours struggeling, I discovered that the library's config setting "new_image" is not working as expected.

I used this code:

Code:

$config['image_library'] = 'gd2';
    $config['source_image'] = "/myexamplepath/imagetoresize.jpg";
    $config['new_image'] = "/myexamplepath/resized_image_tyuiobv"; // some new unique filename
    $config['create_thumb'] = FALSE;
    $config['maintain_ratio'] = TRUE;
    $config['width'] = $max_width;
    $config['height'] = $max_height;

In that case, when you call image_lib->resize(), it tries to write to:

/myexamplepath/resized_image_tyuiobv/imagetoresize.jpg

So, the original filename is concatenated to the new filename! Very strange behaviour in my opinion! Do other users have the same problem?

[eluser]Unknown[/eluser]
It doesnt concat, it makes it a folder because there is no filename extension on the 'new_image' string. Add .jpg to the end of that and I bet it doesn't concat the strings.
