No image cropping

[dhughesbc]

Steps to reproduce

Install alchemy in an existing rails app

Expected behavior

After uploading an image, docs indicate you should be able to crop the image (possibly by clicking on the image? docs not clear).

Actual behavior

Do not see any way to crop an image.

System configuration

• Alchemy Version: 5.0.0
• Rails Version: 6.0.3.2

The image cropping needs to be enabled in he settings of the image content. Also the image needs to be large enough for the desired image size (also a confit on the image content) Could you please paste the link to the docs were it is said that image cropping should be enable for all images?

There is not any specific place it says anything either way, but on this page https://alchemy-cms.com/tour, there is indication that you can crop images. There is no mention that it needs to be explicitly enabled.

Now that I understand it needs to be enabled, I see this in the config: https://github.com/AlchemyCMS/alchemy_cms/blob/master/config/alchemy/config.yml#L63-L79 but it is confusing. This line indicates a hash to set config:

# Alchemy uses Dragonfly to render images. Use {size: "XXXxYYY", crop: BOOLEAN [true]} to resize images.

But this line says to use a string:

# preprocess_image_resize [String] # Use this option to resize images to that value. Downsizing example: '1000x1000>' (Default nil)

The issue for me was confusion the documentation. There is s a comment/example in one config that is meant to be applied in a different config file. I have created a PR that clarifies #1917
