pygmt.Figure.psconvert

Figure.psconvert(*, crop=None, gs_option=None, dpi=None, prefix=None, gs_path=None, resize=None, bb_style=None, fmt=None, anti_aliasing=None, verbose=None, **kwargs)

Convert [E]PS file(s) to other formats.

Converts one or more PostScript files to other formats (BMP, EPS, JPEG, PDF, PNG, PPM, TIFF) using Ghostscript.

If no input files are given, will convert the current active figure (see pygmt.Figure). In this case, an output name must be given using parameter prefix.

Aliases:

  • A = crop

  • C = gs_option

  • E = dpi

  • F = prefix

  • G = gs_path

  • I = resize

  • N = bb_style

  • Q = anti_aliasing

  • T = fmt

  • V = verbose

Parameters:

  • crop (str or bool) – Adjust the BoundingBox and HiResBoundingBox to the minimum required by the image content. Default is True. Append +u to first remove any GMT-produced time-stamps. Append +r to round the HighResBoundingBox instead of using the ceil function. This is going against Adobe Law but can be useful when creating very small images where the difference of one pixel might matter. If verbose is used we also report the dimensions of the final illustration.

  • gs_path (str) – Full path to the Ghostscript executable.

  • gs_option (str) – Specify a single, custom option that will be passed on to Ghostscript as is.

  • dpi (int) – Set raster resolution in dpi. Default is 720 for PDF, 300 for others.

  • prefix (str) – Force the output file name. By default output names are constructed using the input names as base, which are appended with an appropriate extension. Use this option to provide a different name, but without extension. Extension is still determined automatically.

  • resize (str) – [+mmargins][+s[m]width[/height]][+Sscale]. Adjust the BoundingBox and HiResBoundingBox by scaling and/or adding margins. Append +m to specify extra margins to extend the bounding box. Give either one (uniform), two (x and y) or four (individual sides) margins; append unit [Default is set by PROJ_LENGTH_UNIT]. Append +swidth to resize the output image to exactly width units. The default unit is set by PROJ_LENGTH_UNIT but you can append a new unit and/or impose different width and height (Note: This may change the image aspect ratio). What happens here is that Ghostscript will do the re-interpolation work and the final image will retain the DPI resolution set by dpi. Append +sm to set a maximum size and the new width is only imposed if the original figure width exceeds it. Append /height to also impose a maximum height in addition to the width. Alternatively, append +Sscale to scale the image by a constant factor.

  • bb_style (str) – Set optional BoundingBox fill color, fading, or draw the outline of the BoundingBox. Append +ffade to fade the entire plot towards black (100%) [no fading, 0]. Append +gpaint to paint the BoundingBox behind the illustration and append +p[pen] to draw the BoundingBox outline (append a pen or accept the default pen of "0.25p,black,solid"). Note: If both +g and +f are used then we use paint as the fade color instead of black. Append +i to enforce gray-shades by using ICC profiles.

  • anti_aliasing (str) – [g|p|t][1|2|4]. Set the anti-aliasing options for graphics or text. Append the size of the subsample box (1, 2, or 4) [Default is "4"]. [Default is no anti-aliasing (same as bits = 1).]

  • fmt (str) – Set the output format, where b means BMP, e means EPS, E means EPS with PageSize command, f means PDF, F means multi-page PDF, j means JPEG, g means PNG, G means transparent PNG (untouched regions are transparent), m means PPM, and t means TIFF [Default is JPEG]. To b|j|g|t, optionally append +m in order to get a monochrome (grayscale) image. The EPS format can be combined with any of the other formats. For example, ef creates both an EPS and a PDF file. Using F creates a multi-page PDF file from the list of input PS or PDF files. It requires the prefix parameter.

  • 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 algorithms)

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

    • c - Compatibility warnings

    • d - Debugging messages
