Prefix) file formats will again become important, as it was in the lastĪ special coder prefix " implicit::" can be used to 'turn-off' any Of course if an image generatorĪctually reads in an image file to process it in a special way (for example ![]() Vital when reading some file formats such as the " text:" verses the " txt:" file format handling.

This is why the primary IM command is call " magick". The original reason for IM's creation was this sort of image formatĬonversion. Only to magick an image from one image format to another.
