Its value must be between 0 and 256^2 specifying the max geometric distance between colors to be considered equal. The fuzz parameter allows for the fill to cross for adjacent pixels with similarish colors. With image_fill we can flood fill starting at pixel point. Image_modulate(frink, brightness = 80, saturation = 120, hue = 90)

The full syntax is specified in the Magick::Geometry documentation. image_border(frink, "red", "20x10"): adds a border of 20px left+right and 10px top+bottom.image_fill(image, "blue", "+100+200"): flood fill with blue starting at the point at x:100, y:200.image_scale(image, "x200"): resize proportionally to height: 200px.image_scale(image, "200"): resize proportionally to width: 200px.image_crop(image, "100x150+50"): crop out width:100px and height:150px starting +50px from the left.Several of the transformation functions take an geometry parameter which requires a special syntax of the form AxB+C+D where each element is optional. # $ version :Class 'numeric_version' hidden list of 1 # Disabled features: fftw, ghostscript, x11 str(magick::magick_config()) # List of 24 # Enabled features: cairo, fontconfig, freetype, heic, lcms, pango, raw, rsvg, webp library(magick) # Linking to ImageMagick 6.9.12.3 Use magick_config to see which features and formats are supported by your version of ImageMagick. The binary CRAN packages work out of the box and have most important features enabled.
On Windows or macOS the package is most easily installed via CRAN.
