Hello,

is it possible to configure XenForo Media Gallery in a way to the keep the aspect ratio of pictures in Thumbnails? Not to cut something off, but to to fill it with white space?

Thank you in advance!

Kind regards,
Frank

This is kind of a must have. I have a site of fine art photographers and it really is painful for them to have their work misrepresented in the thumbnails. A switch to keep aspect ration would be great. On that note would hiring a coder to make a mod for this be feasible or is this extremely pervasive to adjust?

Hi,

This is feasible, though it's through file editing as your image helper class already as everything that's necessary :)
I did that for sross which is a long time customer of mine so I am posting it here in case it helps some others, and perhaps you could add that as an option in admincp @Chris D ?

Explanations here below are valid for XFMG 1.2.2.

In the same file, replace:
PHP:
        return "<img src=\"{$writeUrl}\" style=\"width: 100%; visibility: {$visibility}\" class=\"dummyImage {$classes}\" title=\"{$title}\" alt=\"{$title}\" />";
By:
PHP:
        return "<img src=\"{$writeUrl}\" style=\"visibility: {$visibility}\" class=\"dummyImage {$classes}\" title=\"{$title}\" alt=\"{$title}\" />";
Btw, if you dont' want smaller sized image (both w/h smaller than max ones) to be resized, add in file library/XenGallery/Helper/Image.php:
PHP:
        if ($height < $max_height && $width < $max_width)
        {
            return true;
        }
Before :
PHP:
        //Want to fit in the area?
        if ($method == 'fit')

Just a quick note to say I have implemented this in XFMG 1.1.9 and all is ok. A few of the line numbers in the tutorial have changed but it's easy enough to find the content :)

No it won't, it was specifically for xF1 and file structure is obviously different.

OK, thanks. This worked really well for 1.x to provide this option for those who wanted/needed it.

@Chris D how hard would this be to adapt for 2.1x?

It sure would be a nice admin control panel option! It probably takes me 1000x longer to figure out the code and adapt it than you, so I thought I'd ask you before I attempt the upgrade. Thanks!
