Allow 'width' or 'height' blank (or '0') values

[augustoms]

To allow resize based on one dimension (like WordPress currently works)

I second that. It would be most helpful as I have just found out that the script currently does not do that. Unfortunately that means it's back to TimThumb for me for now.

Well, I haven't tested this but I believe you can already do that....
If for example you want to resize an image based on its height, you can use something like this:
height: 300
width: 9999 (just a really high value)
crop: false

so basically something like this should do the trick:

<?php matthewruddy_image_resize( $url, 9999, 300, false ); ?>

@aristath I tried the above but the script is actually resizing the image to 9999 x whatever. Can anyone else confirm that the above works?

Here's a fork with proportional cropping enabled (when width or height are set to null or false): https://github.com/proframework/Wordpress-Timthumb-alternative/blob/master/resize.php

This is an amazing script. Thank you. I also would really like to see this ability. @proframework your fork didn't work for me. I've dived in to trying to tweak it myself with no luck so far. Anyone else get it working?

[augustoms]

@coryshaw, the same here. I just copy the code and test (changing, for eg, the height number to false, and a black image appears).

@proframework : I'm doing something wrong? what's the correctly way to use your updated script?

[proframework]

Hmm, my fork above is working well for me. All I have to do is set the width or height to "false", and proportional sizing will kick in.

So it would be something like this..

First we check if width or height is set to false (using a shortcode).

Then we check if the width or height are empty (or false), if so, we turn off cropping.

Then if you do this:

[image width="false" height="300"]

It will resize the image proportionally.

Hope this helps..

Hello @proframework ! Thanks for your attention!

So, I can't understand what I'm doing wrong. Look my steps:

• include your forked code;
• in my template file, I call the function like this:
  $img_des = matthewruddy_image_resize( 'http://www....com/file.jpg', 200, false, true, false );
echo '<img src="'. $img_des['url'].' alt="" />;
• the result is a black image

I'm running it in a local server (OSX + MAMP).

[proframework]

Hi there,

Maybe try this..

$img_des = matthewruddy_image_resize( 'http://www....com/file.jpg', 200, false, false ); echo '<img src="'. $img_des['url'].' alt="" />;

@proframework !
now it runs! the problem was my function markup!
thank you very much!

Glad I could help :)
