Still.Image.Preprocessor.Adapter behaviour (Still v0.8.0) View Source

Adapter definition to be used by Still.Image.Preprocessor.

An adapter implements the render/1 function. It is only called when :image_opts are defined within the :metadata field of the source file (see Still.SourceFile).

The render/1 function should create several versions of the same images, given the :sizes and :transformations options. The purpose of this function is to support the responsive_image/2 template helper. See Still.Image.TemplateHelpers.render_html/2 for details on how this template helper works.

:sizes defines the widths of the output files to create.

:transformations defines the function name and arguments to call on the adapter. By default, the adapter is Still.Image.Preprocessor.Mogrify.

You can change the adapter by altering your config:

config :still, :image_adapter, Still.Image.Preprocessor.Imageflow

The Imageflow adapter requires you to have :still_imageflow as a dependency.
