the.c_margin property.
If automatic page breaking is enabled and the cell goes beyond the limit, a

Args:
w (float): Cell width. Default value: None, meaning to fit text width.
If 0, the cell extends up to the right margin.
h (float): Cell height. Default value: None, meaning an height equal
to the current font size.
text (str): String to print. Default value: empty string.
border: Indicates if borders must be drawn around the cell.
The value can be either a number (`0`: no border ; `1`: frame)

`L`: left ; `T`: top ; `R`: right ; `B`: bottom. Default value: 0.

ln (int): **DEPRECATED since 2.5.1**: Use `new_x` and `new_y` instead.
align (fpdf.enums.Align, str): Set text alignment inside the cell.
Possible values are: `L` or empty string: left align (default value) ;
`C`: center; `X`: center around current x position; `R`: right align
fill (bool): Indicates if the cell background must be painted (`True`)
or transparent (`False`). Default value: False.
link (str): optional link to add on the cell, internal
(identifier returned by `FPDF.add_link`) or external URL.
center (bool): center the cell horizontally on the page.
markdown (bool): enable minimal markdown-like markup to render part
of text as bold / italics / strikethrough / underlined.
Supports `\\` as escape character. Default to False.
txt (str): [**DEPRECATED since v2.7.6**] String to print. Default value: empty string.

This method allows printing text with line breaks. They can be automatic
(breaking at the most recent space or soft-hyphen character) as soon as the text
reaches the right border of the cell, or explicit (via the `\\n` character).
As many cells as necessary are stacked, one below the other.
Text can be aligned, centered or justified. The cell block can be framed and
the background painted. A cell has an horizontal padding, on the left & right sides,
defined by the.c_margin property.
Args:
w (float): cell width. If 0, they extend up to the right margin of the page.
h (float): height of a single line of text. Default value: None, meaning to use the current font size.
text (str): string to print.
border: Indicates if borders must be drawn around the cell.
The value can be either a number (`0`: no border ; `1`: frame)
or a string containing some or all of the following characters
(in any order):
`L`: left ; `T`: top ; `R`: right ; `B`: bottom. Default value: 0.
align (fpdf.enums.Align, str): Set text alignment inside the cell.
Possible values are:
`J`: justify (default value); `L` or empty string: left align;
`C`: center; `X`: center around current x position; `R`: right align
fill (bool): Indicates if the cell background must be painted (`True`)
or transparent (`False`). Default value: False.
split_only (bool): **DEPRECATED since 2.7.4**:
Use `dry_run=True` and `output=("LINES",)` instead.
link (str): optional link to add on the cell, internal
(identifier returned by `add_link`) or external URL.
new_x (fpdf.enums.XPos, str): New current position in x after the call. Default: RIGHT
new_y (fpdf.enums.YPos, str): New current position in y after the call. Default: NEXT
ln (int): **DEPRECATED since 2.5.1**: Use `new_x` and `new_y` instead.
max_line_height (float): optional maximum height of each sub-cell generated
markdown (bool): enable minimal markdown-like markup to render part
of text as bold / italics / strikethrough / underlined.
Supports `\\` as escape character. Default to False.
print_sh (bool): Treat a soft-hyphen (\\u00ad) as a normal printable
character, instead of a line breaking opportunity. Default value: False
wrapmode (fpdf.enums.WrapMode): "WORD" for word based line wrapping (default),
"CHAR" for character based line wrapping.
dry_run (bool): if `True`, does not output anything in the document.
Can be useful when combined with `output`.
output (fpdf.enums.MethodReturnValue): defines what this method returns.
If several enum values are joined, the result will be a tuple.
txt (str): [**DEPRECATED since v2.7.6**] string to print.
center (bool): center the cell horizontally on the page.
padding (float or Sequence): padding to apply around the text. Default value: 0.
When one value is specified, it applies the same padding to all four sides.
When two values are specified, the first padding applies to the top and bottom, the second to
the left and right. When three values are specified, the first padding applies to the top,
the second to the right and left, the third to the bottom. When four values are specified,
the paddings apply to the top, right, bottom, and left in that order (clockwise)
If padding for left or right ends up being non-zero then respective c_margin is ignored.
Center overrides values for horizontal padding
Using `new_x=XPos.RIGHT, new_y=XPos.TOP, maximum height=pdf.font_size` is
useful to build tables with multiline text in cells.
Returns: a single value or a tuple, depending on the `output` parameter value

Args:
name: either a string representing a file path to an image, an URL to an image,
bytes, an io.BytesIO, or a instance of `PIL.Image.Image`
x (float, fpdf.enums.Align): optional horizontal position where to put the image on the page.
If not specified or equal to None, the current abscissa is used.
`fpdf.enums.Align.C` can also be passed to center the image horizontally;
and `fpdf.enums.Align.R` to place it along the right page margin
y (float): optional vertical position where to put the image on the page.
If not specified or equal to None, the current ordinate is used.
After the call, the current ordinate is moved to the bottom of the image
w (float): optional width of the image. If not specified or equal to zero,
it is automatically calculated from the image size.
Pass `pdf.epw` to scale horizontally to the full page width.
h (float): optional height of the image. If not specified or equal to zero,
it is automatically calculated from the image size.
Pass `pdf.eph` to scale horizontally to the full page height.
type (str): [**DEPRECATED since 2.2.0**] unused, will be removed in a later version.
link (str): optional link to add on the image, internal
(identifier returned by `FPDF.add_link`) or external URL.
title (str): optional. Currently, never seem rendered by PDF readers.
alt_text (str): optional alternative text describing the image,
for accessibility purposes. Displayed by some PDF readers on hover.
dims (Tuple[float]): optional dimensions as a tuple (width, height) to resize the image
before storing it in the PDF. Note that those are the **intrinsic** image dimensions,
but the image will still be rendered on the page with the width (`w`) and height (`h`)
provided as parameters. Note also that the `.oversized_images` attribute of FPDF
provides an automated way to auto-adjust those intrinsic image dimensions.
keep_aspect_ratio (bool): ensure the image fits in the rectangle defined by `x`, `y`, `w` & `h`
while preserving its original aspect ratio. Defaults to False.
Only meaningful if both `w` & `h` are provided.
If `y` is provided, this method will not trigger any page break;
otherwise, auto page break detection will be performed.
