Hi Sven

I already made a similar ticket (#2619).
You gave some guidance of what php file to edit and possibly what code.

However it turns out I'm just too foreign with PHP code, and I'm hoping you can help me out once again.

In the previous ticket you mentioned the solution would be to edit in following:
components\com_eventgallery\library\common\imageprocessor.php

It would be more than fine if it could just be a white background (or if possible a transparent background).
As you've mentioned in previous ticket there should be a solution in some comments here stackoverflow.com

Also I bought the Extended Event Gallery which works great thank you!

Having transparent images will not work since the thumbnails are always jpeg files. But you can change the background like this.

Add this to the resize function in the file components\com_eventgallery\library\common\imageprocessor.php

// set background to white
$white = imagecolorallocate($image, 255, 255, 255);
imagefill($image, 0, 0, $white);

I attached a screenshot and hope this helps.

by the way, you're sending auto reply message containing Christmas greetings. The ticket system does not like this very much ;)

Thank you for the reply!

First of I'm so sorry about the auto reply. When I bought the extended version I changed the email to my colleague responsible for invoices, who is currently on a business trip, but apparently set a wrong autoreply, which I have now fixed for her... >D

Also I have changed this account back to my email again. I was unaware that it was a change of account mail when I wrote what email to confirm the subscription to, and was actually wondering why I didn't get a mail of your response.
Everything should work out now :)

Second I've tried to add your code, but I'm afraid it didnt do much... Except now the sites got a little problem loading either thumbnails or lightbox versions and I have to refresh page for it to work.

I read in some comments on stackoverflow, that it might be an alpha setting needed?

I doubt the code would work on already uploaded images? The way I tested the new code, is by creating a new Event Album and uploading new images. You can see my site here.

Sorry if I'm confusing!

It seems to work... a bit.

Did you add that code in the right place? Does not look like this.

To see changes you need to clear the thumbnail cache on the server. Otherwise you only see the old cached versions.

Hmm I'm not seeing any examples of it working >.<

Ive added 3 images.
imageprocessor_code.jpg = How it looks in my code now.
onmyscreen.jpg = How it looks after I cleared all cache in joomla.
theimageyoulinked = Your image example got a black background on my screen?

Ups... I send you the wrong code snippet :)

// set background to white
        $white = imagecolorallocate($im_output, 255, 255, 255);
        imagefill($im_output, 0, 0, $white);

THANK GOD!
Seriously tho I thought I was going crazy xD "Am I clearing cache wrong??" Haha

Everything looks great for me now. Thank you very much! I've added an image of how I've changed it to look :)

Have tried 3 different galleries.
This is now the first one for me, which can actually render an acceptable background for my transparent images!

I'll close this ticket :)
