Image Transform in template 'Auto' errors The docs state:


  format can be set to 'jpg', 'gif', 'png', or 'Auto'.


*Why is it 'Auto' not 'auto'?!

https://craftcms.com/docs/image-transforms#possible-values

I'm using a variable to define the transform settings:

{% set small = {
    mode:       'fit',
    width:      800,
    height:     600,
    quality:    80,
    position:   'center-center',
    format:     'Auto'
} %}


But Craft errors with:


  Imagine\Exception\InvalidArgumentException Saving image in "auto"
  format is not supported, please use one of the following extensions:
  "gif", "jpeg", "png", "wbmp", "xbm"


Is this a bug or is my code incorrect?
This was an error in the docs. You get the automatic format assignment by default, no need to explicitly set format: 'auto'.
