Custom fonts can be used by specifying full path to a font file in your Media Library
l_<imagePath> => oi-<imagePath>
Full path to the overlaid image in the Media Library must be specified
t_<transform_name> => n-<transform_name>
ImageKit does not translate the actual underlying transformations associated with your named transforms. They must be manually translated and added in your ImageKit dashboard while retaining the same name.
Marks the end of a group of transformations being applied in the context of an overlay. ImageKit detects the presence of an fl_layer_apply and applies the relevantly positioned transforms to the overlaid asset instead of the main asset.
Note: The rewriter will silently ignore any transformation that has a valid key, but with an invalid value. For example, h_100,w_<invalid>/a_90 will be translated to h-100:rt-90. Refer to the table to see what constitutes a valid value for different transforms.
