下面以圖片為背景，展示圖片輪廓的雲圖

from PIL import Image
img = Image.open('./testporject/girl.png')
plt.imshow(img)

<matplotlib.image.AxesImage at 0x7fa9cc262ac8>
 

img_array = np.array(img)
cloud_m = WordCloud(width=1440, height=1080,mask = img_array).generate(" ".join(train_qs.astype(str)))
plt.figure(figsize=(20, 15))
plt.imshow(cloud_m)
plt.axis('off')

cloud_m.to_file('cloud.png')

下面是以圖片背景顏色為字型顏色實現

image_colors = ImageColorGenerator(img_array) # 讀取背景檔案色彩
 

plt.figure(figsize=(20, 15))
plt.imshow(cloud_m.recolor(color_func=image_colors))

用到的文字CalltoArms.txt是魯迅吶喊的節選。

import jieba
font = './testporject/FZSTK.TTF'
text = (open('./testporject/CalltoArms.txt','r',encoding='utf-8')).read()
cut = jieba.cut(text)  #分詞
string_ch = ' '.join(cut)
print(len(string_ch))
cloud_ch = WordCloud(width=1440, height=1080,
                     mask = img_array,
                    font_path=font).generate(string_ch)
plt.figure(figsize=(20, 15))
plt.imshow(cloud_ch)
plt.axis('off')
