Hi there. I’ve built a few text-driven Kirby sites (on 1.x and 2.0), and I’m looking into how Kirby can work with images, especially generating a few images from a source.
I knew there was a built-in tool in K2 for that, but the only doc I could find was this page from the cheatsheet (and I first I had only found a one-liner from the toolkit doc): http://getkirby.com/docs/cheatsheet/helpers/thumb
So I wanted to know, are there more docs around for this feature? Broad information on how it works, how it can be configured (if at all)?
It might also be a good idea to mention this feature (and link to the cheatsheet entry or a more elaborate doc) in this page: http://getkirby.com/docs/content/media
Right now you basically have to know already that Kirby can do this, and fish for the right cheatsheet entry. I wouldn’t be surprised if, as a result, many developers end up just using big JPEG images for thumbnails. So ideally (ping @bastianallgeier) this information would be easier to find and a bit more user-friendly.
Hello – indeed infos on the whole thumbs() handling are a bit sparse; a good starting point is the actual source which lists all available parameters. When the function was available as a plugin in Kirby 1, there was a more thorough doc which I can’t find for the moment.
Some notes from the top of my head:
if you pass a boolean at the end of the function, it outputs the URL only, like thumb($image, array('width' => 960, 'crop' => true, 'quality' => 50), false);
which is great for generating sources for multiple resolutions (don’t forget to note those in the filename var, or they are only separated via different hashes)
You can force file formats by setting the extension in 'filename' => '{safeName}-{hash}.{extension}'
Thumb toolkit uses a fork the Simpleimage lib, but doesn’t make use of all of it’s options – with a bit of fiddling, you have access to more filters this way.
