Subject: [PATCH] fix: issue of corrupted PNG file.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Some corrupted PNG files will trigger error messages during parsing, but data is still read from them, and we process them following the normal procedure.
某些已损坏的PNG文件解析时会报错，但同时也读取到了数据，我们按正常流程处理。
