image: center, left or right side

[bwakad]

Unfortunatly I did not find information of front-end image crop. But I did notice images can be manipulated for output using:

$thumb = $page->image->size(200,200); echo "<img src='{$thumb->url}'/>";

It looks like a center -cropping, -clipping, or -resize (not sure).

Since an uploaded image in landscape let me see the center part of the big image.

My question: is there a function in pw, to be used in forms, that let users choose to display center, left or right ?

I think not a "special PW-function" but what's about radio buttons in your form with left - center - right and within form processing you crop the images west - center or east, according to the selected radio button?

was thinking about that too. But in the docs on pw it says these options can be placed in the config. That leaves me with only 1 option...

Uhh? Where does it say that? This would be new to me.

(good reference is here)

link from the PW docs "images" (there are 2 entries for images) ... http://processwire.com/api/fieldtypes/images/

You may modify the default $options that your system uses by adding a $config->imageSizerOptions in your /site/config.php file:

$config->imageSizerOptions = array( 'upscaling' => true, 'cropping' => true, 'quality' => 90, );

A little further it says: You may specify any of the following for the $options array:of which cropping as direction is part of it.If I can set these in config, then I am bound by 1. Correct?

not correct

From the docs

$options = array(
  'quality' => 90,
  'upscaling' => false, 
  'cropping' => 'southeast' 
);  
$img = $image->size($x, $y, $options);

it says: default option, not the only one you can have. As far as I know defaults, they will be taken if you have not specified an individual value for something.

Oh okay, so in the options are just defaults as fallback. And in templates I can use different. Thanks!
