matplotlib.backends.backend_ps

A PostScript backend, which can produce both PostScript .ps and .eps.

matplotlib.backends.backend_ps.FigureCanvas

alias of FigureCanvasPS

class matplotlib.backends.backend_ps.FigureCanvasPS(figure=None)

Bases: FigureCanvasBase

draw()

Render the Figure.

This method must walk the artist tree, even if no output is produced, because it triggers deferred work that users may want to access before saving output to disk. For example computing limits, auto-limits, and tick values.

filetypes = {'eps': 'Encapsulated Postscript', 'ps': 'Postscript'}

fixed_dpi = 72

get_default_filetype()

Return the default savefig file format as specified in rcParams["savefig.format"] (default: 'png').

The returned string does not include a period. This method is overridden in backends that only support a single file type.

print_eps(outfile, *, metadata=None, papertype=None, orientation='portrait', bbox_inches_restore=None, **kwargs)

print_ps(outfile, *, metadata=None, papertype=None, orientation='portrait', bbox_inches_restore=None, **kwargs)

class matplotlib.backends.backend_ps.RendererPS(width, height, pswriter, imagedpi=72)

Bases: RendererPDFPSBase

The renderer handles all the drawing primitives using a graphics context instance that controls the colors/styles.

create_hatch(hatch, linewidth)

draw_gouraud_triangles(gc, points, colors, trans)

Draw a series of Gouraud triangles.

Parameters:

gcGraphicsContextBase

The graphics context.

triangles_array(N, 3, 2) array-like

Array of N (x, y) points for the triangles.

colors_array(N, 3, 4) array-like

Array of N RGBA colors for each point of the triangles.

transformTransform

An affine transform to apply to the points.
