classmatplotlib.backends.backend_pdf.PdfPages(filename, keep_empty=True, metadata=None)[source]
Bases: object A multi-page PDF file. Notes In reality PdfPages is a thin wrapper around PdfFile, in order to avoid confusion when using savefig and forgetting the format argument. Examples >>> import matplotlib.pyplot as plt
>>> # Initialize:
>>> with PdfPages('foo.pdf') as pdf:
... # As many times as you like, create a figure fig and save it:
... fig = plt.figure()
... pdf.savefig(fig)
... # When no figure is specified the current figure is saved
... pdf.savefig()
Create a new PdfPages object. Parameters
filenamestr or path-like or file-like
Plots using PdfPages.savefig will be written to a file at this location. The file is opened at once and any older file with the same name is overwritten.
keep_emptybool, optional
If set to False, then empty pdf files will be deleted automatically when closed.
metadatadict, optional
Information dictionary object (see PDF reference section 10.2.1 'Document Information Dictionary'), e.g.: {'Creator': 'My software', 'Author': 'Me', 'Title': 'Awesome'}. The standard keys are 'Title', 'Author', 'Subject', 'Keywords', 'Creator', 'Producer', 'CreationDate', 'ModDate', and 'Trapped'. Values have been predefined for 'Creator', 'Producer' and 'CreationDate'. They can be removed by setting them to None. attach_note(text, positionRect=[- 100, - 100, 0, 0])[source]
Add a new text note to the page to be saved next. The optional positionRect specifies the position of the new note on the page. It is outside the page per default to make sure it is invisible on printouts.

draw_gouraud_triangle(gc, points, colors, trans)[source]
Draw a Gouraud-shaded triangle. Parameters
gcGraphicsContextBase
The graphics context.
points(3, 2) array-like
Array of (x, y) points for the triangle.
colors(3, 4) array-like
RGBA colors for each point of the triangle.
transformmatplotlib.transforms.Transform
An affine transform to apply to the points.
draw_gouraud_triangles(gc, points, colors, trans)[source]
Draw a series of Gouraud triangles. Parameters
points(N, 3, 2) array-like
Array of N (x, y) points for the triangles.
colors(N, 3, 4) array-like
Array of N RGBA colors for each point of the triangles.
transformmatplotlib.transforms.Transform
An affine transform to apply to the points.
draw_image(gc, x, y, im, transform=None)[source]
Draw an RGBA image. Parameters
gcGraphicsContextBase
A graphics context with clipping information.
xscalar
The distance in physical units (i.e., dots or pixels) from the left hand side of the canvas.
yscalar
The distance in physical units (i.e., dots or pixels) from the bottom side of the canvas.
im(N, M, 4) array-like of np.uint8
An array of RGBA pixels.
transformmatplotlib.transforms.Affine2DBase
If and only if the concrete backend is written such that option_scale_image() returns True, an affine transformation (i.e., an Affine2DBase) may be passed to draw_image(). The translation vector of the transformation is given in physical units (i.e., dots or pixels). Note that the transformation does not override x and y, and has to be applied before translating the result by x and y (this can be accomplished by adding x and y to the translation vector defined by transform).
draw_markers(gc, marker_path, marker_trans, path, trans, rgbFace=None)[source]
Draw a marker at each of path's vertices (excluding control points). This provides a fallback implementation of draw_markers that makes multiple calls to draw_path(). Some backends may want to override this method in order to draw the marker only once and reuse it multiple times. Parameters
gcGraphicsContextBase
The graphics context.
marker_transmatplotlib.transforms.Transform
An affine transform applied to the marker.
transmatplotlib.transforms.Transform
An affine transform applied to the path.
draw_mathtext(gc, x, y, s, prop, angle)[source]
draw_path(gc, path, transform, rgbFace=None)[source]
Draw a Path instance using the given affine transform.
draw_path_collection(gc, master_transform, paths, all_transforms, offsets, offsetTrans, facecolors, edgecolors, linewidths, linestyles, antialiaseds, urls, offset_position)[source]
Draw a collection of paths selecting drawing properties from the lists facecolors, edgecolors, linewidths, linestyles and antialiaseds. offsets is a list of offsets to apply to each of the paths. The offsets in offsets are first transformed by offsetTrans before being applied. offset_position is unused now, but the argument is kept for backwards compatibility. This provides a fallback implementation of draw_path_collection() that makes multiple calls to draw_path(). Some backends may want to override this in order to render each set of path data only once, and then reference that path multiple times with the different offsets, colors, styles etc. The generator methods _iter_collection_raw_paths() and _iter_collection() are provided to help with (and standardize) the implementation across backends. It is highly recommended to use those generators, so that changes to the behavior of draw_path_collection() can be made globally.
draw_tex(gc, x, y, s, prop, angle, *, mtext=None)[source]
draw_text(gc, x, y, s, prop, angle, ismath=False, mtext=None)[source]
Draw the text instance. Parameters

xfloat

yfloat
The y location of the text baseline in display coords.
sstr
The text string.
propmatplotlib.font_manager.FontProperties
The font properties.
anglefloat
The rotation angle in degrees anti-clockwise.
mtextmatplotlib.text.Text
The original text object to be rendered. Notes Note for backend implementers: When you are trying to determine if you have gotten your bounding box right (which is what enables the text layout/alignment to work properly), it helps to change the line in text.py: if 0: bbox_artist(self, renderer)
to if 1, and then the actual bounding box will be plotted along with your text.

get_image_magnification()[source]
