Parameter	Description	Allowed Values	Default Value
image_format	Specify the output format.	jpg, png, gif, tiff	jpg
size	Specify the size of the output.	WxH or Wx0 or 0xH or Wx or xH, where W and H are positive integers.	None
keep_aspect_ratio	Specify whether to keep width to height ratio of original picture.	yes, no	yes
resize_method	Specify how the original picture will be transformed to new size.	resize, crop, combine	resize
quality	Specify the level of JPEG quality.	jpg: 1-100 All: none	80
dpi	Specify the image DPI.	71-1200	72
sharpen_radius	Specify the output sharpen radius.	0-10	0
sharpen_sigma	Specify the amount of image sharpening. (recommendation is 0.5-1.0)	Float: 0, 0.2-10	0.5
gravity	Sets the current gravity suggestion for various other options.	northwest, north, northeast, west, center, east, southwest, south, southeast	None
remove_metadata	Specify whether to remove image metadata including EXIF.	yes, no	no
shave	Specify how many pixels to shave from the image edges.	WxH	None
unsharp_radius	Specify the radius of the gaussian.	In pixels, not counting the center pixel, should be larger than unsharp_sigma. Use a radius of 0 to have the method select a suitable radius.	None.
unsharp_sigma	Specify the standard deviation of the gaussian.	In pixels	1.0
unsharp_gain	Specify the fraction of the difference between the original and the blur image that is added back into the original.	Float	1.0
unsharp_threshold	Specify the threshold, as a fraction of QuantumRange, needed to apply the difference amount.	Float	0.05

❗️
For image_format parameter
<image_format /> is a required field.

🚧
For keep_aspect_ratio parameter
If either <width /> or <height /> is set to 0, <keep_aspect_ratio /> will be yes.
