我们从Python开源项目中，提取了以下25个代码示例，用于说明如何使用binascii.rledecode_hqx()。
def _fill(self, wtd): self.pre_buffer = self.pre_buffer + self.ifp.read(wtd+4) if self.ifp.eof: self.post_buffer = self.post_buffer + \ binascii.rledecode_hqx(self.pre_buffer) self.pre_buffer = '' return # # Obfuscated code ahead. We have to take care that we don't # end up with an orphaned RUNCHAR later on. So, we keep a couple # of bytes in the buffer, depending on what the end of # the buffer looks like: # '\220\0\220' - Keep 3 bytes: repeated \220 (escaped as \220\0) # '?\220' - Keep 2 bytes: repeated something-else # '\220\0' - Escaped \220: Keep 2 bytes. # '?\220?' - Complete repeat sequence: decode all # otherwise: keep 1 byte. # mark = len(self.pre_buffer) if self.pre_buffer[-3:] == RUNCHAR + '\0' + RUNCHAR: mark = mark - 3 elif self.pre_buffer[-1] == RUNCHAR: mark = mark - 2 elif self.pre_buffer[-2:] == RUNCHAR + '\0': mark = mark - 2 elif self.pre_buffer[-2] == RUNCHAR: pass # Decode all else: mark = mark - 1 self.post_buffer = self.post_buffer + \ binascii.rledecode_hqx(self.pre_buffer[:mark]) self.pre_buffer = self.pre_buffer[mark:]
