Tweaking the new media uploader "Scale to..." option

[mtwelve]

Hello,


Right... what I'm looking to do is utilize the new "Scale images to match the large size..." to resize images to a size I dictate that is not the default "Large" size.
I've found where the new function is configured; lines 1340-1341 in \wp-admin\icludes\media.php

var resize_height = <?php echo get_option('large_size_h', 500); ?>,
resize_width = <?php echo get_option('large_size_w', 500); ?>,

Now I have a temporary fix; I've replaced the options it calls with some I've inserted myself... the thing is I'm editing the core files as I don't know if I can filter this...? (I presume I want to filter?) Can anyone with a stronger knowledge have a look...?


The other thing is to make sure that the box always stays checked; or at least is checked by default. Its mentioned here as being not too tricky, any advice?



The new uploader is fantastic and if I can just sort these two bits out then it saves using some rather temperamental code.


Massive Thanks

this

set_user_setting ('upload_resize', true);

in funtions.php seems to automatically check the box

So I was digging around on trac.wordpress.org to see if anyone else was discussing/suggesting solutions that would fix my issue. I found this but I don't think its quite relevant; is it?

Made me think though that as there clearly isn't a filter or hook (could someone confirm which I'm searching for) to tap into then, I (we) would need to submit something and press for it to be included in the next release.

I was thinking of something last night like this

function set_resize_on_upload_options() {   
$resize_image_h = get_option('large_size_h', 750);
$resize_image_w = get_option('large_size_w', 750);
}


<script type="text/javascript">
var resize_height = <?php echo $resize_image_h; ?>,
resize_width = <?php echo $resize_image_w; ?>,
wpUploaderInit = <?php echo json_encode($plupload_init); ?>;
</script>

My patchy knowledge hints that as the variables are enclosed in a function you could just substitute that function in your own functions.php or maybe it needs a hook within the function.

Even if Im way off any nudges in the right direction would be great so I can start a campaign to get this noticed.


Many Thanks!

Huh?

You are trying to make a custom image size? There's a function for that: http://codex.wordpress.org/Function_...add_image_size

[mtwelve]

no no no...

The next version of WordPress has a check box on the 'New Media' lightbox that will resize the 'Full Size' image to match the 'Large Size' set in Media Settings; thus removing the original 'Full Size' image and leaving you it resized.

The current setup (lines 1340-1341 in \wp-admin\icludes\media.php) uses the settings that you set for the Large image size in Media Settings. It uses large_size_h and large_size_w and then falls back to the other value 500.

I want to be able to modify which options it calls and/or manually set the size without modifying the core files.

Looking through the media.php file I cant see how that is possible but Im not well versed on filters/actions but I'm very keen to make a song and dance about it as this would put the icing on the cake of the new uploader.

Cheers

You can return a different value by hooking into the option filter.

apply_filters( 'pre_option_' . $option, false );

Sorry to be an absolute a*se but can you walk me through it

---

Would this filter that size/option for the whole installation; as in would it make all large images the size specified by the filter or just within that function?

Filters as far as I was aware needed for there to be an apply_filters in the line your looking to change...?


Many Thanks!

Well there is a filter
so you would write

 if(media uploader loaded){//so not always change the large_scale values, but only when you want to.
  apply_filters('pre_option_large_size_h','prefix_set_new_full_scale_h',0);
  function prefix_set_new_full_scale_h($h){
      return 250;
  }
  apply_filters('pre_option_large_size_w','prefix_set_new_full_scale_w',0);
  function prefix_set_new_full_scale_w($w){
      return 500;
  }
}
