For the following examples, we will use this as our input, in.jpg:

Example 1: Check dimensions of image

$ icl in.jpg
Loaded 'in.jpg' (336 by 252).

Example 2: Convert to png

$ icl in.jpg -o in.png
Loaded 'in.jpg' (336 by 252).
Saved as 'in.png' (336 by 252).

Example 3: Various effects

$ icl in.jpg blur
$ icl in.jpg desaturate
$ icl in.jpg sharpen2
$ icl in.jpg negate

Example 4: Drawing stuff

$ icl 336x252 fill black -o pic.jpg
$ icl pic.jpg line 0 0 336 251 white -o pic.jpg
$ icl pic.jpg circle 150 100 100 white -o pic.jpg
$ icl pic.jpg text 10 10 Hello red "Times New Roman" 30 -o pic.jpg
$ icl pic.jpg ascii 10 50 World green 4 -o pic.jpg

Example 5: Steganography

$ icl in.jpg hide pic.jpg -o secret_message.png
$ icl secret_message.png unhide -o message.jpg

This tool has many more features, like resizing, scaling, cropping, blitting, rotating, flipping, etc... See usage for full list.


	icl [input] [command] [args] [-o output]

	-[input] is a PNG, BMP, or JPEG image
	-[command] is a single command. See below for list of commands.
	-[args] is the arguments for the command
	-[output] is where to save the file. If not specified, the default
	 is 'out.png'

	crop [x] [y] [width] [height]
	fill [color]
	interpolate [image|color] [alpha]
	blend [image] [alpha] [beta]
	blur [radius (default=10)]
	sharpen [amount (default=3.0)]
	sharpen2 [amount (default=3.0)] [blur radius (default=2)]
	saturate [amount (default=3.0)]
	brighten [amount (default=1.25)]
	lazy_resize [width] [height]
	lazy_scale [ratio]
	resize [width] [height]
	scale [ratio]
	threshold [amount (0-255)]
	text [x] [y] [text] [color] [face (default=Tahoma)] [size (default=12)] [transparent (default=false)]
	blit [image] [x] [y] [use_alpha (default=true)]
	rect [x] [y] [width] [height] [color] [filled (default=false)]
	line [x1] [y1] [x2] [y2] [color]
	circle [x] [y] [radius] [color] [filled (default=false)]
	flip [x-axis (true or false)] [y-axis (true or false)]
	cinema => do cinema effect (sharpen, slightly desaturate, and more shadow)
	find_exact [image] => find coordinates of image in input
	find_fuzzy [image] => quickly find coordinates of image in input
	ascii [x] [y] [text] [color] [scale (default=2)]
	ascii_table [scale (default=2)]
	dither [image] [bits (default=2)]
	hide [image] [bits (default=2)] => hide image within this image (steganography)
	unhide [bits (default=2)] => reveal image hidden within this image, if any

	Input can be in the following format to create a new image:
	  [width (default=1)]x[height (default=1)]

	Colors can be specified in one of the following formats:
	  RGBA hex: #rrggbbaa
	  RGB hex: #rrggbb
	  RGBA hex, 16-bit: #rgba
	  RGB hex, 16-bit: #rgb
	  RGBA tuple: rgba(r,g,b,a)
	  RGB tuple: rgb(r,g,b)
	  HSLA tuple: hsl(h,s,l,a)
	  HSL tuple: hsl(h,s,l)
	  Constant: white, black, red, green, blue, orange, purple, yellow

	For the tuples, RGB must be [0,255], alpha must be [0,1],
	hue must be [0,360), saturation [0,1], and lightness [0,1].
	If alpha is not specified, it is assumed to be 0xff (255).

How is this better than ImageMagick?

It's less typing, smaller, and easier to use.
