Fit

Resizes the image to fit into a specified width and height box, adds padding (image or solid colour) to keep proportions, and delivers the resulting image via CDN.

func=fit

The padding can be customised using the following additional operations:

function	name	description
gravity	gravity=X X = [north \| south][east \| west]	sets the position of the image in the fit box
solid background	bg_colour=X \| bg_color=X	defines a background colour either with a hex code or colour name
	bg_colour=auto \| bg_color=auto	extracts the most prominent colour from the image and uses it as a background colour
blurred background	bg_img_fit=1	sets blurred image background
	bg_blur=X	applies Gaussian blur to the background image
	bg_opacity=X X = 0..1	specifies background image opacity
	bg_colourise=X \| bg_colorize=X	defines a colour to tint the background image

For details, please see the solid background section.

Blurred background

/v7/sample.li/car1.jpg?w=400&h=320&
func=fit&bg_img_fit=1&bg_opacity=0.75

All options are listed in the blurred background section.

Gravity

The gravity=X operation sets the position of the image when padding is added. Possible values are:

northwest	north	northeast
west	centre \| center	east
southwest	south	southeast

If not explicitly set, the default gravity is centre.

For example, by setting gravity to south, the image is positioned at the bottom and the padding is added at the top.

Fit to 250x250px, centre gravity

/v7/sample.li/earth.jpg?func=fit&
w=250&h=250&bg_colour=10100E&
gravity=centre

Fit to 250x250px, south gravity

/v7/sample.li/earth.jpg?func=fit&
w=250&h=250&bg_colour=10100E&
gravity=south

Enabling image upscaling

By default, the fit operation does not upscale the image if the original is smaller than the requested dimensions. If you wish to enable upscaling when using fit, you can use the fit_enlarge=1 option.
