N.B. Until 1.0 is reached, each beta release my include backwards incompatible changes. 1.0 will include parsing and writing of PNGs and JPEGs.
Image parsing in Elixir.
Currently Imagineer only supports PNGs. To load an image, create a new Imagineer.Image and pass it to the load function. Once the image is processed (or the raw binary is placed in the raw field by some other means), passing it to process will parse all of its data.
alias Imagineer.Image
image = %Image{uri: "./test/support/images/alpaca.png"}
|> Image.load
|> Image.process
