How to use shrinkRatio method about bulletproof HOT 7 CLOSED

Hi.

It seems @petervanderdoes was the author of that feature, I merged without much evaluation. Will look more into this, sorry for the delay and any inconvenience.

This shrink(array("width"=>1000, "height"=>1000, "shrinkRatio"=>true)) is the wrong format. it should be
shrink(array("width"=>1000, "height"=>1000), true))

The command is shrink(array(width,height), ratio, upsize)

The ratio can set to true or false depending on whether or not you want to keep the ratio of the photo, defaults to false.
The upsize can be set to true or false depending on whether or not you want to upsize the image if the given width/height is larger than the original image, defaults to true.

Currently there is no easy way to only resize on width or height. That would need further coding.

Currently if I use: shrink(array("width"=>1000, "height"=>1000), true)

That will shrink the image but doesn't keep the ratio. It seems to squash the image so it has a 1000px width but doesn't adjust the height correctly / not at all.

EDIT: Looks like It needs a bit of playing with. After adjusting the height to only 100px the ratio was kept. I will have a good read at the shrink code and get my head around what is happening.

@CraigLovelock
Does it not adjust the height, or does it not correctly adjust it?

What were the original dimensions of the image you wanted to shrink?

@petervanderdoes I believe @CraigLovelock has asked similar question in detail in SO I agree the ratio resize feature is very important, I will see if I can add a clearer code/example soon

Pull Request #21 allows for resizing by either width or height. If you give the width and set height to NULL the image is resized for the given width and what the new height will be does not matter.
