Thanks for asking, I’m sure other users must be curious too:

“f_type”:“png” File type output

“width”:800, width of the image

“height”:500, height of the image

“s_max”:“7”, Scale factor max (scale factor - this is like the font size for the most popular word)

“s_min”:“1”, Scale factor min (scale factor - this is like the font size for the least popular word)

“f_min”:1, Minimum frequency of the word considered relevant - if you set to 3 it will ignore any words that occur less than 3 times.

“r_color”:“TRUE”, Random colors. Colors tied to popularity.

“r_order”:“TRUE”, Random order. Not random will cluster the more popular words in the center.

“s_fit”:“FALSE”, Careful with this one - it will keep reducing the font size parameters till all words fit. It could take a very long time to process.

“fixed_asp”:“TRUE”, Will enforce the output to be fixed X and Y lengths. It will appear square even if the width and height are rectangular.

“rotate”:“TRUE”, Rotate words or all horizontal words

“textblock”:"" Text to be used

Note: Variable aspect ratio (fixed_asp = FALSE) only works if rotate == FALSE.
