Mode: string ( default = "RGB") //When the parameter is "RGBA" and background_color is not empty, the background is transparent. Max_font_size: int or None ( default =None) //The largest font size displayed
Stopwords: set of strings or None //Set the words that need to be blocked, if it is empty, use the built-in STOPWORDSīackground_color: color value ( default =”black”) //Background color, such as background_color='white', the background color is white. Max_words: number ( default = 200 ) //The maximum number of words to be displayed Min_font_size: int ( default = 4 ) //The smallest font size displayedįont_step: int ( default = 1 ) //Font step size, if the step size is greater than 1, it will speed up the calculation but may lead to larger errors in the result. If set to 1.5, the length and width are both 1.5 times of the original canvas. scale : float ( default = 1 ) //Enlarge the canvas according to the ratio. You can use the ps tool to copy the shape you want to display to a pure white canvas and save it. For example: bg_pic = imread('Read a picture.png'), the canvas of the background picture must be set to white (#FFFFFF), and then the displayed shape is other colors other than white. The part except for all white (#FFFFFF) will not be drawn, and the rest will be used to draw the word cloud. If the mask is not empty, the set width and height values will be ignored, and the mask shape will be replaced by mask. Mask: nd-array or None ( default =None) //If the parameter is empty, use a two-dimensional mask to draw the word cloud. Prefer_horizontal: float ( default = 0.90 ) //The frequency of words typesetting in the horizontal direction, the default is 0.9 (so the frequency of words typesetting in the vertical direction is 0.1)
Height: int ( default = 200 ) //The height of the output canvas, the default is 200 pixels Width: int ( default = 400 ) //The width of the output canvas, the default is 400 pixels The font is by no means integral, and any other font can be used by setting the font_path variable when creating a WordCloud object.Font_path: string //Font path, write the font path + suffix name for what font you need to display, such as: font_path ='黑体.ttf' The wordcloud library is MIT licenced, but contains DroidSansMono.ttf, a true type font by Google, that is apache licensed. Use wordcloud_cli -help so see all available options. In the previous example, the - argument orders pdftotext to write the resulting text to stdout, which is then piped to the stdin of wordcloud_cli.py.

If you're dealing with PDF files, then pdftotext, included by default with many Linux distribution, comes in handy: $ pdftotext mydocument.pdf - | wordcloud_cli -imagefile wordcloud.png The wordcloud_cli tool can be used to generate word clouds directly from the command-line: $ wordcloud_cli -text mytext.txt -imagefile wordcloud.png
Or run examples/masked.py to see more options. ExamplesĬheck out examples/simple.py for a short intro. Before installing a compiler, reportĪn issue describing the version of python and operating system being used. Package requires having a C compiler set up. If there are no wheels available for your version of python, installing the To save the wordcloud into a file, matplotlib can also be installed.
