How does the image parser work?

[Jaxel]

Okay... lets say I have the URL to an image stored in a string:
http://i.ytimg.com/vi/kCVZv-cPC10/hqdefault.jpg

I want to take this image, crop resize from center into a 160x90 image... then store it into a jpg file...

Any idea how to do this?

 

[Jaxel]

GOT IT! wow this was so much easier than vBulletin! This is how to do it... feel free to use in your own mods!

	// get extension of image
	$extension = XenForo_Helper_File::getFileExtension($input['media_thumb']);

	// get width, height and type of image
	$imageInfo = @getimagesize($input['media_thumb']);

	// set target save location
	$targetloc = XenForo_Helper_File::getInternalDataPath().'/media/1.'.$extens;

	// create image object from existing image
	if ($image = XenForo_Image_Abstract::createFromFile($input['media_thumb'], $imageInfo[2]))
	{
		// resize image object to 160 width
		$image->thumbnail('160');

		// get image height and determine its distance from 90
		$height = $image->getHeight();
		$offset = ($height - 90) / 2;

		// crop image height to 90 from center, extend if shorter
		$image->crop('0', $offset, '160', '90');

		// save thumbnail image to target location
		$image->output($imageInfo[2], $targetloc);
	}

If you wanted... you could force a JEPG file type for your thumbnails... (you could do the same with GIF and PNG)

		$targetLoc = XenForo_Helper_File::getInternalDataPath().'/media/1.jpg';
		$imageInfo = @getimagesize($input['media_thumb']);

		if ($image = XenForo_Image_Abstract::createFromFile($input['media_thumb'], $imageInfo[2]))
		{
			$image->thumbnail('160');

			$height = $image->getHeight();
			$offset = ($height - 90) / 2;

			$image->crop('0', $offset, '160', '90');
			$image->output(IMAGETYPE_JEPG, $targetLoc);
		}

I know this is Off Topic, but I have noticed a trend... You REALLY like working with xF don't you?

People like myself appreciate the work you do and it's great and very helpful, but I get a kick out of it when you're asking a question and figure it out and then find out it's easier than vB..

If I only knew how to code... so I could have some fun!

Yes... I'm loving XenForo... I'm not happy with having to rewrite my Media Library mod... but cesta la vie...

But it appears that the /internal_data/ path isn't accessable from the browser...

Does anyone know an alternative to getInternalDataPath for the regular data path?

Beta 3 exposes it. Prior to that, no.

Okay... is there a function to get the external data URL (not path)?

Looking for this in both TEMPLATES and in models.

 

[Kier]

The external data path is always expressed as a relative URL from the base path.

XenForo_Helper_File::getInternalDataPath() will return "/home/path/to/website/data" for me... thats not an URL, thats a PATH... I want to be able to get xen1.8wayrun.com/data in a variable automatically... since I know people can change the location of their data folder.

 

[Kier]

You asked for the external path / URL.

[Jaxel]

You asked for the external path / URL.

Yes... the external URL... by default its yourwebsite.com/data

However, in the config, you can change the external data path to something else... its why you guys created the getExternalDataPath function. However, in my templates I am hardcoding "data/" as the external data URL... is there a way to automatically get the external data URL, the same way that getExternalDataPath gets the external data PATH?

 

[Kier]

XenForo_Helper_File::getExternalDataPath() will always return a realtive path to the base URL, so it can be combined with the base URL to form an absolute URL, or used on its own as a relative URL. Either way, it can be used as a URL within your templates.

Okay... how would I use this in combination with the base url? Is there a function to get the base url?

If I use getExternalDataPath by itself, I NEVER get a relative path, it ALWAYS gives me the full path from root.

 

[Kier]

Aaaah, sorry, I'm talking crap. You actually want XenForo_Application::$externalDataPath - that is the relative path.

Thanks... now how do I get the base url? I tried this:

$external = XenForo_Link::buildPublicLink('full:'.XenForo_Application::$externalDataPath.'/media');

works... but I think there should be a better way...

Is this what you are looking for?

            $options = XenForo_Application::get('options');

            $boardUrl = $options->boardUrl;

If you're working from within the XenForo template system, there is no need for anything else, the base URL is already in place.

Assuming that you pass the value of XenForo_Application::$externalDataPath out via the $viewParams in your public controller, you can simply link to it directly - ie:

return $this->responseView('My_ViewPublic_Something', 'some_template', array(
 'dataPath' => XenForo_Application::$externalDataPath));

<a href="{$dataPath}/path/to/something">Something</a>

Or am I missing something here? If so, what exactly are you trying to achieve?[/php]
