類

基類已重命名，因?yàn)樗鼈冞€允許使用 ByteIO 流而不是文件進(jìn)行操作。此外，?strict? 參數(shù)將默認(rèn)值從 ?strict=True? 更改為 ?strict=False?。

  • PdfFileReader ? PdfReader

  • PdfFileWriter ? PdfWriter

  • PdfFileMerger ? PdfMerger

PdfFileReader 和 PdfFileMerger 不再有 ?overwriteWarnings? 參數(shù)。新行為是 ?overwriteWarnings=False?。
