Operations
Basic image resizing operations
Resizing operations enable the dynamic generation of image transformations to meet various web delivery use cases. Operations focus on the image size while allow to modify the image itself.
Available operations
width=X
sets the image width to X pixels
height=X
sets the image height to X pixels
org_if_sml=1
prevents resizing if the target size is larger than the origin image
func=crop
sets crop resize function
gravity=X
defines the part of the image to be retained when cropping X = [north | south][east | west] | auto | X,Y
tl_px=X,Y
sets coordinates of the top left corner of the cropping rectangle
br_px=X,Y
sets coordinates of the bottom right corner of the cropping rectangle
func=face
crops the image automatically focusing on the most prominent face
func=fit
sets fit resize function
func=cropfit
sets crop or fit resize function depending on the origin and the desired dimensions
func=bound
sets bound resize function
func=boundmin
bounds the image to the larger dimension
func=cover
sets cover resize function (distorts image proportions)
flip=[h][v]
mirrors the image horizontally and/or vertically
r=X
rotates the image to X degrees (counterclockwise)
trim=X
trims any solid-color border (if present); X is the aggressiveness of the operation
radius=X
applies rounded corners and optionally fills the empty background with a color
Resize functions
When you specify both width and height, original image proportions can be either ignored or maintained. Also, you may choose to add padding to the image to fill the blank space.
Filerobot supports the following resize function (operation func).
Crop
Keeps image proportions cutting the image to fit the defined width and height; see
This resizing function removes parts of the image and is the default behaviour when both width and height are defined. Read further for other resizing functions.
Fit
Resizes the image keeping proportions and adding padding to satisfy the desired dimensions; see
Cropfit
Performs either Cropor Fit based on image dimensions and transformation parameters; see
This resizing function may remove parts of the image
Bound
Fits image in a box of defined size without adding padding; see
Cover
Resizes the image to the given width and height ignoring original image proportions, thus distorting the image; see
