@item :format
ImageMagick tries to auto-detect the image type, but it isn't always
able to. By using @code{:format-type}, we can give ImageMagick a hint
-to try to help it. It's used in conjuction with the
+to try to help it. It's used in conjunction with the
@code{image-format-suffixes} variable, which provides a mapping from
content types to file name suffixes. This is then given to
ImageMagick as a file name hint.
