示例1: emotion_to_avatar
# 需要导入模块: from pgmagick import Image [as 别名]
# 或者: from pgmagick.Image import trim [as 别名]
def emotion_to_avatar(emotion, font_path, color=Color("black")):
"""使用颜文字(文本)来生成一张方形图片
:type emotion: string
:param emotion: 需要绘制在图像上的文本
:type font_path: string
:param font_path: 字体文件路径
:type color: Color
:param color: 绘制的文本颜色
返回结果是一个 Image 对象，并叫将会被规整到 AVATAR_SIZE 设定的大小
