WordCloud.WordCloud — Module

The WordCloud.jl package is a flexible, faithful and efficient word cloud generator in Julia.

using WordCloud
 wc = wordcloud("It's easy to generate a beautiful word cloud.") |> generate!
-paint(wc, "wordcloud.svg")

Please visit the repository at: https://github.com/guo-yong-zhi/WordCloud.jl

source
WordCloud.configsvgimages! — Function

For editing SVGs of words. The 1st argument is wordcloud, the 2nd optional argument is index which can be string, number, list, or any other standard supported index. There are two kinds of keyword arguments, children and wrappers. The nodes in children will be linked under the root node of the SVG. The nodes in wrappers will be inserted between the SVG root node and all its child nodes. The children will be wraped by the wrapper node. A node is represented as a String Pair. e.g.

  • child "title"=>"word" for <title>word</title>
  • child "title"=>("word", :lang=>"en-us") for <title lang="en-us">word</title>
  • child "animate" => ["attributeName"=>"opacity", "to"=>"0", "dur"=>"6s"] for <animate attributeName="opacity" to="0" dur="6s"/>
  • wrapper "a"=>("href"=>"https://www.google.com") for <a href="https://www.google.com"> and </a>

Arguments children and wrappers can be a Pair, or a Tuple of Pairs to add multiple nodes to a SVG. Again, giving a list of Tuples of Pairs is ok to edit multiple SVGs corresponding to the index argument.

  • recolor!(wc, style=:blending, alpha=0.3) # The alpha parameter is optional
  • recolor!(wc, style=:reset)

The effects of :average, :main, and :clipping are determined solely by the background. However, the effect of :blending is also influenced by the previous color of the word. Therefore, :blending can also be used in combination with other styles. The results of clipping and blending cannot be exported as SVG files; PNG should be used instead.

source
WordCloud.TextProcessing.rescaleweights — Function
rescaleweights(func=identity, p=0)

This function takes word length into account. Therefore, the rescaled weights can be used as font size coefficients. The function func(w::Real)->Real is used to remap the weight, expressed as weight = func(weight); p represents the exponent of the power mean. We set weight = powermean(1*fontsize, wordlength*fontsize) = ((fontsize^p + (wordlength*fontsize)^p)/2) ^ (1/p). That is, weight = fontsize * powermean(1, wordlength). Overall, this gives us fontsize = func(weight) / powermean(1, wordlength). When p is -Inf, the power mean is the minimum value, resulting in fontsize=weight. When p is Inf, the power mean is the maximum value, resulting in fontsize=weight/wordlength. When p is -1, the power mean is the harmonic mean. When p is 0, the power mean is the geometric mean, preserving the word area. When p is 1, the power mean is the arithmetic mean. When p is 2, the power mean is the root mean square, preserving the diagonal length.

WordCloud.recolor! — Method

Recolor the words according to the pixel color in the background image. The styles supported are :average, :main, :clipping, :blending, and :reset (to undo all effects of the other styles).

Examples

  • recolor!(wc, style=:average)
  • recolor!(wc, style=:main)
  • recolor!(wc, style=:clipping, background=blur(getmask(wc))) # The background parameter is optional
  • recolor!(wc, style=:blending, alpha=0.3) # The alpha parameter is optional
  • recolor!(wc, style=:reset)

The effects of :average, :main, and :clipping are determined solely by the background. However, the effect of :blending is also influenced by the previous color of the word. Therefore, :blending can also be used in combination with other styles. The results of clipping and blending cannot be exported as SVG files; PNG should be used instead.

source
WordCloud.TextProcessing.rescaleweights — Function
rescaleweights(func=identity, p=0)

This function takes word length into account. Therefore, the rescaled weights can be used as font size coefficients. The function func(w::Real)->Real is used to remap the weight, expressed as weight = func(weight); p represents the exponent of the power mean. We set weight = powermean(1*fontsize, wordlength*fontsize) = ((fontsize^p + (wordlength*fontsize)^p)/2) ^ (1/p). That is, weight = fontsize * powermean(1, wordlength). Overall, this gives us fontsize = func(weight) / powermean(1, wordlength). When p is -Inf, the power mean is the minimum value, resulting in fontsize=weight. When p is Inf, the power mean is the maximum value, resulting in fontsize=weight/wordlength. When p is -1, the power mean is the harmonic mean. When p is 0, the power mean is the geometric mean, preserving the word area. When p is 1, the power mean is the arithmetic mean. When p is 2, the power mean is the root mean square, preserving the diagonal length.
