pathlib.Path) specifying the name of an existing file. It is also possible to open a document from memory data, or to create a new, empty PDF. See Document for details. You can also use Document as a context plain text with line breaks. No formatting, no text position details, no images. • “blocks”: generate a list of text blocks (= paragraphs). • “words”: generate a list of words (strings not containing spaces) try to open it as a . So in these cases there is no need for additional precautions. Similarly, for memory documents, you can just specify doc=fitz.open(stream=mem_area) to open it as a document. If you

A document contains many attributes repaired document in memory for further processing. If this is the case, the document is regarded as being modified. After a document has been decrypted, the document in memory has changed and also counts reader(fname): ifile = open(fname, "rb") idata = ifile.read() # put in memory ifile.close() ibuffer = BytesIO(idata) # convert to stream try:

Statements. New in version 2.2. trim_blocks If this is set to True the first newline after a block is re- moved (block, not variable tag!). Defaults to False. lstrip_blocks If this is set to True leading spaces template owning this context. blocks A dict with the current mapping of blocks in the template. The keys in this dict are the names of the blocks, and the values a list of blocks registered. The last item templates from a resource such as the file sys- tem. The environment will keep the compiled modules in memory like Python’s sys.modules. Unlike sys.modules however this cache is limited in size by default and
