描述

clip() is supposed to take an argument to specify the clipping rule. Context2D drops this argument on the floor and implements the default clipping rule, I guess.

It can also be given two arguments where one argument is the path. This is also not implemented.

研究方向
Explore the Context2D implementation in jsPDF, likely in src/context2d.js or similar. The current clip() method should be located and compared with the MDN specification. The fix needs to handle the optional `fillRule` argument and the two argument variant where the first argument is a path. Look for how other methods like `fill()` or `stroke()` handle similar arguments. Review any existing tests for clip() in the test directory.
