Working with Image Filters

So basically I was just gonna uh because there has been quite a lot of discussion about these image filters uh this week. Um so I just want to show you a little bit about well, basically what's possible. Um when we were doing this uh we found this well basically undocumented hook called register image operations where you can register uh filter operations uh in your Loctile hooks pie. And every one of those is basically a uh pillow um image so it's uh it's a it's a willow

operation where you uh where you have a function that takes in a pillow image and basically returns another pillow image after you've done something with it. Then you have this filter operation with a construct and a run that's basically runs this function. Um so I had a little fun and made a couple of filters Just so I could show you how this works. So we have like grayscale and we have flip and mirror and a couple of things. And all you have to do is basically use the current image tag and you can then just add stuff to the back of it.

So here we have an image basically Yeah, just a normal image of some landscape. And we want a grayscale version. So then you can just add grayscale here and you have a grayscale version. And you can uh because of how these work you can just day chain them so you can just add more if you want. So you want to take You know a grayscale one that's flipped and mirrored. Then you have something that's mil I mean many of these filters are not really usable.

I mean they don't make sense in most use cases, but there are cases where you can use them and It's things like watermarks. It's things like uh like multiply, for us at least. Uh so for for this kind I I want to try to um like add variables so you can actually just do multiply and then add any hex variable that you want so multiply this with a gray color. Then you get like a grayish background thing. If you wanna go crazy, you can go with completely red And you can so you can just play around with this. Um and just

to kinda um end this, uh I did try to do a little bit of masking as well. So I have a image that is basically a grayscale image of a watercolor. mask so you can then you can just add watercolor and then you'll get something that's completely different just by masking out out things like this. Kuhn was doing some documentation on this. So hopefully we'll have some documentation on this register. image filter and uh uh and there was also some work done on uh creating a hook that kind of bypasses all this all this boilerplate

So yeah, hopefully someone can use some of this.
