X Title: Caching the results of Transform.transform_path for non-affine transforms by pelson · Pull Request #723 · matplotlib/matplotlib

Description: This pull request supports the previously intended capability of caching non-affine transformations. It was discussed briefly on the devel mailing-list: http://old.nabble.com/Caching-the-results-of-Transform.transform_path-for-non-affine-transforms-td33256890.html An example of how to test this capability by hand was included on the thread: import matplotlib.transforms class SlowNonAffineTransform(matplotlib.transforms.Transform): input_dims = 2 output_dims = 2 is_separable = False has_inverse = True def transform(self, points): return matplotlib.transforms.IdentityTransform().transform(points) def transform_path(self, path): # pretends that it is doing something clever & time # consuming, but really is just sleeping import time # take a long time to do something time.sleep(3) # return the original path return matplotlib.transforms.IdentityTransform().transform_path(path) if __name__ == '__main__': import matplotlib.pyplot as plt ax = plt.axes() ax.plot([0, 10, 20], [1, 3, 2], transform=SlowNonAffineTransform() + ax.transData) plt.show()
