glyph (if its one line), or the (number of lines * linespacing + M)/2. That is,
it will try to have it be center-left as close as possible.
:param font: A font class that has ``get_bounding_box`` and ``get_glyph``.
Must include a capital M for measuring character size.
:type font: ~BuiltinFont, ~BDF, or ~PCF

:param int color: Color of all text in RGB hex
:param int background_color: Color of the background, use `None` for transparent
:param float line_spacing: Line spacing of text to display
:param bool background_tight: Set `True` only if you want background box to tightly
surround text. When set to 'True' Padding parameters will be ignored.
:param int padding_top: Additional pixels added to background bounding box at top.
This parameter could be negative indicating additional pixels subtracted from the
background bounding box.
:param int padding_bottom: Additional pixels added to background bounding box at bottom.
This parameter could be negative indicating additional pixels subtracted from the
background bounding box.
:param int padding_left: Additional pixels added to background bounding box at left.
This parameter could be negative indicating additional pixels subtracted from the
background bounding box.
:param int padding_right: Additional pixels added to background bounding box at right.
This parameter could be negative indicating additional pixels subtracted from the
background bounding box.
:param (float,float) anchor_point: Point that anchored_position moves relative to.
Tuple with decimal percentage of width and height.
(E.g. (0,0) is top left, (1.0, 0.5): is middle right.)
:param (int,int) anchored_position: Position relative to the anchor_point. Tuple
containing x,y pixel coordinates.
:param int scale: Integer value of the pixel scaling
:param bool base_alignment: when True allows to align text label to the baseline.
This is helpful when two or more labels need to be aligned to the same baseline
:param (int,str) tab_replacement: tuple with tab character replace information. When
(4, " ") will indicate a tab replacement of 4 spaces, defaults to 4 spaces by
tab character

**Quickstart: Importing and using the SHT4x temperature and humidity sensor**
Here is an example of using the :class:`SHT4x`.
First you will need to import the libraries to use the sensor
.. code-block:: python
import board
import adafruit_sht4x
Once this is done you can define your `board.I2C` object and define your sensor object
.. code-block:: python
i2c = board.I2C() # uses board.SCL and board.SDA
sht = adafruit_sht4x.SHT4x(i2c)
You can now make some initial settings on the sensor
.. code-block:: python
sht.mode = adafruit_sht4x.Mode.NOHEAT_HIGHPRECISION
Now you have access to the temperature and humidity using the :attr:`measurements`.
It will return a tuple with the :attr:`temperature` and :attr:`relative_humidity`
measurements
.. code-block:: python
temperature, relative_humidity = sht.measurements
