Python Image 模块,ROTATE_270 实例源码
我们从Python开源项目中,提取了以下9个代码示例,用于说明如何使用Image.ROTATE_270。
def getmask2(self, text, mode="", fill=Image.core.fill):
size, offset = self.font.getsize(text)
im = fill("L", size, 0)
self.font.render(text, im.id, mode=="1")
return im, offset
##
# Wrapper that creates a transposed font from any existing font
# object.
#
# @param font A font object.
# @param orientation An optional orientation. If given,this should
# be one of Image.FLIP_LEFT_RIGHT,Image.FLIP_TOP_BottOM,
# Image.ROTATE_90,Image.ROTATE_180,or Image.ROTATE_270.
def getsize(self, text):
w, h = self.font.getsize(text)

return h, w
return w, h

textdraw.text((0,0), font=font, fill=fill)
