image add variation

[hdesigns]

I'm working on a little image resizing module that hooks in after the image was uploaded in the back end (based on Somas code).

But unlike Soma I use GD to generate the resized (and slightly modified image). So, before there are any questions: Yes I need to use GD instead of $image->size(...)

The resizing works but I would really like to add my variation (my resized image) to the $image->getVariations. First of all because I want to get my resized image to be deleted when the original image was deleted and second because of consistency reasons.

Simple question: How can I add my self-generated image to the PW-image variations?

This is something that I am sure horst will follow up on, but as far as I know, the only thing you need to do (or can do), is to make sure the filename matches the conventions for variations: https://github.com/ryancramerdesign/ProcessWire/blob/7b9730d43e6eda8bd27841a4811a1b9737bfe903/wire/core/Pageimage.php#L484

If you need a different filename format that isn't automatically detected by the core isVariation() method that I pointed to above, you can hook it and modify like I have done here: https://github.com/adrianbj/ImageRasterizer/blob/master/ImageRasterizer.module#L243

Hope that helps until our image expert sees this!

I'd never thought it could be so easy. But it is!

Thanks adrian!
