This structure holds the details of a line in the TSV formatted text provided by the tesseract library.

Values:

Name	Description
level	Identifies what the line describes.
page	This is the page number passed into the `tess_tsv()` method.
block	Identifies the block on the page.
paragraph	The paragraph number in the block.
line	The line in the paragraph.
word	The word in the line.
left	Left edge of the item in pixels.
top	Top edge of the item in pixels.
width	Width of the item in pixels.
height	Height of the item in pixels.
conf	How confident the OCR engine is of the word (`0` - `100`). `-1` if level is not 5.
text	The word that was decoded from the image.

Details:

Level identifies what information the line is providing:

1 - Page information, added at the start of the page.
2 - Block information, added at the start of a block.
3 - Paragraph information, added at the start of a paragraph.
4 - Line information, added at the start of a line.
5 - Word information, identifies a word that was read from the page.

The left, top, width, and height values define a box in pixels that encompases the item. So if the level is 1, the box describes the whole image. If the level is 1, then the box encloses the block that was extracted, and so on down to the word that was extracted.
