한글 워드클라우드 생성하기

워드클라우드를 만드는 도중 한글 단어가 출력되지 않는 문제가 발생하였다.

 

상기문제는 한글FONT 를 설정하지 않아서 생긴 문제다. 아래처럼 한글 폰트의 경로를 추가한다.

wc = WordCloud(max_words=2000, mask=parrot_mask, font_path="C:\Windows\Fonts\H2HDRM.TTF",max_font_size=40, random_state=42, relative_scaling=0)
#wc = WordCloud(max_words=2000, mask=parrot_mask, max_font_size=40, random_state=42, relative_scaling=0)

 

한글폰트를 추가후 확인시 한글이 정상적으로 표현되는 것을 확인 할 수 있다.

"""
Image-colored wordcloud with boundary map
=========================================
A slightly more elaborate version of an image-colored wordcloud
that also takes edges in the image into account.
Recreating an image similar to the parrot example.
