Specify a 2D transformation.
The transformation between two coordinate systems is represented by a 3-by-3
transformation matrix written as follows::
a b 0
c d 0
e f 1
Because a transformation matrix has only six elements that can be changed,
it is usually specified in PDF as the six-element array [ a b c d e f ].
Coordinate transformations are expressed as matrix multiplications::
a b 0
[ x′ y′ 1 ] = [ x y 1 ] × c d 0
e f 1

PageObjecta!
PageObject represents a single page within a PDF file.
Typically this object will be created by accessing the
:meth:`get_page()` method of the
:class:`PdfReader` class, but it is
also possible to create an empty page with the
:meth:`create_blank_page()` static method.
:param pdf: PDF file the page belongs to.
:param indirect_reference: Stores the original indirect reference to
this object in its source PDF

Locate all text drawing commands, in the order they are provided in the
content stream, and extract the text. This works well for some PDF
files, but poorly for others, depending on the generator used. This will
be refined in the future. Do not rely on the order of text coming out of
this function, as it will change if this function is made more
sophisticated.

Locate all text drawing commands, in the order they are provided in the

This works well for some PDF files, but poorly for others, depending on

Do not rely on the order of text coming out of this function, as it
will change if this function is made more sophisticated.
Arabic, Hebrew,... are extracted in the good order.
If required an custom RTL range of characters can be defined; see function set_custom_rtl
Additionally you can provide visitor-methods to get informed on all operands and all text-objects.
For example in some PDF files this can be useful to parse tables.

:param float space_width: force default space width

:param Optional[Function] visitor_operand_before: function to be called before processing an operand.
It has four arguments: operand, operand-arguments,
current transformation matrix and text matrix.
:param Optional[Function] visitor_operand_after: function to be called after processing an operand.
It has four arguments: operand, operand-arguments,
current transformation matrix and text matrix.
:param Optional[Function] visitor_text: function to be called when extracting some text at some position.
It has five arguments: text, current transformation matrix,
text matrix, font-dictionary and font-size.
The font-dictionary may be None in case of unknown fonts.
If not None it may e.g. contain key "/BaseFont" with value "/Arial,Bold".

If there is a key called 'BaseFont', that is a font that is used in the document.
If there is a key called 'FontName' and another key in the same dictionary object
that is called 'FontFilex' (where x is null, 2, or 3), then that fontname is
embedded.
We create and add to two sets, fnt = fonts used and emb = fonts embedded.
