pygmt.Figure.image

Figure.image(imagefile, **kwargs)

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 https://docs.generic-mapping-tools.org/latest/image.html

Aliases:

• D = position

• F = box

• J = projection

• M = monochrome

• R = region

• V = verbose

• X = xshift

• Y = yshift

• c = panel

• p = perspective

• t = transparency

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 (str) – Required if this is the first plot command. projcode[projparams/]width. Select map projection.

• region (str or list) – Required if this is the first plot command. xmin/xmax/ymin/ymax[+r][+uunit]. Specify the region of interest.

• position (str) – [g|j|J|n|x]refpoint+rdpi+w[-]width[/height][+jjustify][+nnx[/ny] ][+odx[/dy]]. Sets reference point on the map for the image.

• box (bool or str) – [+cclearances][+gfill][+i[[gap/]pen]][+p[pen]][+r[radius]][+s[[dx/dy/][shade]]]. Without further arguments, draws a rectangular border around the image using MAP_FRAME_PEN.

• monochrome (bool) – Convert color image to monochrome grayshades using the (television) YIQ-transformation.

• verbose (bool or str) –

  Select verbosity level [Default is w], which modulates the messages written to stderr. Choose among 7 levels of verbosity:

  • q - Quiet, not even fatal error messages are produced

  • e - Error messages only

  • w - Warnings [Default]

  • t - Timings (report runtimes for time-intensive algorthms);

  • i - Informational messages (same as verbose=True)

  • c - Compatibility warnings

  • d - Debugging messages

• xshift (str) – [a|c|f|r][xshift]. Shift plot origin in x-direction.

• yshift (str) – [a|c|f|r][yshift]. Shift plot origin in y-direction. Full documentation is at https://docs.generic-mapping-tools.org/latest/gmt.html#xy-full.

• panel (bool or int or list) – [row,col|index]. Selects a specific subplot panel. Only allowed when in subplot mode. Use panel=True to advance to the next panel in the selected order. Instead of row,col you may also give a scalar value index which depends on the order you set via autolabel when the subplot was defined. Note: row, col, and index all start at 0.

• perspective (list or str) – [x|y|z]azim[/elev[/zlevel]][+wlon0/lat0[/z0]][+vx0/y0]. Select perspective view and set the azimuth and elevation angle of the viewpoint. Default is [180, 90]. Full documentation is at https://docs.generic-mapping-tools.org/latest/gmt.html#perspective-full.

• transparency (int or float) – Set transparency level, in [0-100] percent range. Default is 0, i.e., opaque. Only visible when PDF or raster format output is selected. Only the PNG format selection adds a transparency layer in the image (for further processing).
