示例1: stop_filter
# 需要导入模块: from matplotlib.backend_bases import RendererBase [as 别名]
# 或者: from matplotlib.backend_bases.RendererBase import stop_filter [as 别名]
def stop_filter(self, post_processing):
return RendererBase.stop_filter(self, post_processing)
"""
Save the plot in the current canvas as a image and apply
the *post_processing* function.
def post_processing(image, dpi):
# ny, nx, depth = image.shape
# image (numpy array) has RGBA channels and has a depth of 4.
...
# create a new_image (numpy array of 4 channels, size can be
# different). The resulting image may have offsets from
# lower-left corner of the original image
return new_image, offset_x, offset_y
The saved renderer is restored and the returned image from
post_processing is plotted (using draw_image) on it.
