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

  • 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. 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 options, 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 (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.

  • 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 (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).
