LZW 和 CGPDFScanner
CGPDFScanner 是否解压缩它遇到的任何 LZW 压缩?还是我要为此负责? [我假设它确实如此,因为我正在使用大量 Tj
运算符等]
Does CGPDFScanner decompress any LZW-compression it encounters? Or am I responsible for this? [I'm assuming it does because I'm picking up plenty of Tj
operators etc.]
是的,
CGPDFScanner
将解压缩它找到的任何压缩流。您不需要手动执行此操作。Yes,
CGPDFScanner
will decompress any compressed streams it finds. You don't need to do that manually.
