Minimum Width min-w

The minimum allowed width of the output image.

Must be an integer greater than 0. This parameter will only work if fit=crop is present.

This feature is particularly useful for horizontally-scrolling feeds that display user-uploaded images. By specifying a minimum width for each image, useful previews will still be generated for very tall, skinny panoramas.

fit=crop&h=200&min-w=50
Min width 50px, not expanded
fit=crop&h=200&min-w=300
Min width 300px, expanded

See the API specification for more information about this parameter's value ranges and format.
