Output File Description
=========================
After executing the ``magic-pdf`` command, in addition to outputting
files related to markdown, several other files unrelated to markdown
will also be generated. These files will be introduced one by one.
some_pdf_layout.pdf
~~~~~~~~~~~~~~~~~~~
Each page layout consists of one or more boxes. The number at the top
left of each box indicates its sequence number. Additionally, in
``layout.pdf``, different content blocks are highlighted with different
background colors.
.. figure:: ../../_static/image/layout_example.png
:alt: layout example
layout example
some_pdf_spans.pdf
~~~~~~~~~~~~~~~~~~
All spans on the page are drawn with different colored line frames
according to the span type. This file can be used for quality control,
allowing for quick identification of issues such as missing text or
unrecognized inline formulas.

The format of the poly coordinates is [x0, y0, x1, y1, x2, y2, x3, y3],
representing the coordinates of the top-left, top-right, bottom-right,
and bottom-left points respectively. |Poly Coordinate Diagram|

In the above table, ``para_blocks`` is an array of dicts, each dict
representing a block structure. A block can support up to one level of
nesting.
**block**
The outer block is referred to as a first-level block, and the fields in
the first-level block include:
+---------+-------------------------------------------------------------+
| Field | Description |
| Name | |
+=========+=============================================================+
| type | Block type (table|image) |
+---------+-------------------------------------------------------------+
| bbox | Block bounding box coordinates |
+---------+-------------------------------------------------------------+
| blocks | list, each element is a dict representing a second-level |
| | block |
+---------+-------------------------------------------------------------+
There are only two types of first-level blocks: “table” and “image”. All
other blocks are second-level blocks.
The fields in a second-level block include:
+-----+----------------------------------------------------------------+
| Fi | Description |
| eld | |
| N | |
| ame | |
+=====+================================================================+
| t | Block type |
| ype | |
+-----+----------------------------------------------------------------+
| b | Block bounding box coordinates |
| box | |
+-----+----------------------------------------------------------------+
| li | list, each element is a dict representing a line, used to |
| nes | describe the composition of a line of information |
+-----+----------------------------------------------------------------+
Detailed explanation of second-level block types

image_caption Image description text
table_body Main body of the table
table_caption Table description text

================== ======================
**line**
The field format of a line is as follows:
+-----+----------------------------------------------------------------+
| Fi | Description |
| eld | |

| ans | describe the composition of the smallest unit |
+-----+----------------------------------------------------------------+
**span**
+----------+-----------------------------------------------------------+
| Field | Description |

+==========+===========================================================+
| bbox | Bounding box coordinates of the span |
+----------+-----------------------------------------------------------+
| type | Type of the span |
+----------+-----------------------------------------------------------+
| content | Text spans use content, chart spans use img_path to store |
| \| | the actual text or screenshot path information |

The types of spans are as follows:

**Summary**
A span is the smallest storage unit for all elements.
The elements stored within para_blocks are block information.
The block structure is as follows:
First-level block (if any) -> Second-level block -> Line -> Span
