Place images or EPS files on maps.
Reads an Encapsulated PostScript file or a raster image file and plots
it on a map.
Full option list at :gmt-docs:`image.html`

Parameters
----------
imagefile : str
This must be an Encapsulated PostScript (EPS) file or a raster
image. An EPS file must contain an appropriate BoundingBox. A
raster file can have a depth of 1, 8, 24, or 32 bits and is read
via GDAL. **Note**: If GDAL was not configured during GMT installation
then only EPS files are supported.
{projection}
{region}
position : str
[**g**\|\ **j**\|\ **J**\|\ **n**\|\ **x**]\ *refpoint*\ **+r**\ *dpi*\
**+w**\ [**-**]\ *width*\ [/*height*]\ [**+j**\ *justify*]\
[**+n**\ *nx*\ [/*ny*]]\ [**+o**\ *dx*\ [/*dy*]].
Set reference point on the map for the image.
box : bool or str
[**+c**\ *clearances*][**+g**\ *fill*][**+i**\ [[*gap*/]\ *pen*]]\
[**+p**\ [*pen*]][**+r**\ [*radius*]][**+s**\ [[*dx*/*dy*/][*shade*]]].
If set to ``True``, draw a rectangular border around the image
using :gmt-term:`MAP_FRAME_PEN`.
bitcolor : str or list
[*color*][**+b**\|\ **f**\|\ **t**].
Change certain pixel values to another color or make them transparent.
For 1-bit images you can specify an alternate *color* for the
background (**+b**) or the foreground (**+f**) pixels, or give no color
to make those pixels transparent. Can be repeated with different
settings. Alternatively, for color images you can select a single
*color* that should be made transparent instead (**+t**).
monochrome : bool
Convert color image to monochrome grayshades using the (television)
YIQ-transformation.
