Cropping

[Idaho]

First I'd like to say what a great scrip this is, it's saved me so
much time.

I noticed I can change: public static $defaultCropper =
SLIR::CROP_CLASS_TOP_CENTERED
and the image is cropped from the top. It would be quite cool to be
able to also crop from the bottom. I haven't figured out how to do it
yet.

It would also be good if we could change it from CROP_CLASS_CENTERED
to CROP_CLASS_TOP_CENTERED or CROP_CLASS_BOTTOM_CENTERED on an image
by image basis.

Any thoughts guys?

The ability to specify a crop type on an image by image basis is built into the code - there just doesn't seem to be any documentation for it.

you can do it like this for example

<img src="/slir/w150-h100-c15x10xsmart/path/to/image.jpg"/>

I have added xsmart to the crop parameter

you can use:

xcentered

xtopcentered

xsmart

To crop from the bottom create a file in 

core\libs\gd\croppers\

which is a copy of topcentered.class.php

and edit to this:

  public function getCropY(SLIRImage $image)
  {
     return $image->getHeight() - $image->getCropHeight();
  }

Also need to change the class name

You then need to add in a parameter which is the same name as the filename you created into 

core\slir.class.php

apologies to the author if any of this is incorrect, but it has worked for me
