bresenham¶

skimage.draw.bresenham()¶

Generate line pixel coordinates.

Parameters :

Parameters :	y, x : int Starting position (row, column). y2, x2 : int End position (row, column).
Returns :	rr, cc : (N,) ndarray of int Indices of pixels that belong to the line. May be used to directly index into an array, e.g. `img[rr, cc] = 1`.

y, x : int

Starting position (row, column).

y2, x2 : int

End position (row, column).

Returns :

rr, cc : (N,) ndarray of int

Indices of pixels that belong to the line. May be used to directly index into an array, e.g. img[rr, cc] = 1.

circle¶

skimage.draw.circle()¶

Generate coordinates of pixels within circle.

Parameters :

Parameters :	cy, cx : double Centre coordinate of circle. radius: double : Radius of circle.
Returns :	rr, cc : ndarray of int Pixel coordinates of circle. May be used to directly index into an array, e.g. `img[rr, cc] = 1`.

cy, cx : double

Centre coordinate of circle.

radius: double :

Radius of circle.

Returns :

rr, cc : ndarray of int

Pixel coordinates of circle. May be used to directly index into an array, e.g. img[rr, cc] = 1.

ellipse¶

skimage.draw.ellipse()¶

Generate coordinates of pixels within ellipse.

Parameters :

Parameters :	cy, cx : double Centre coordinate of ellipse. b, a: double : Minor and major semi-axes. `(x/a)2 + (y/b)2 = 1`.
Returns :	rr, cc : ndarray of int Pixel coordinates of ellipse. May be used to directly index into an array, e.g. `img[rr, cc] = 1`.

cy, cx : double

Centre coordinate of ellipse.

b, a: double :

Minor and major semi-axes. (x/a)**2 + (y/b)**2 = 1.

Returns :

rr, cc : ndarray of int

Pixel coordinates of ellipse. May be used to directly index into an array, e.g. img[rr, cc] = 1.

line¶

skimage.draw.line()¶

Generate line pixel coordinates.

Parameters :

Parameters :	y, x : int Starting position (row, column). y2, x2 : int End position (row, column).
Returns :	rr, cc : (N,) ndarray of int Indices of pixels that belong to the line. May be used to directly index into an array, e.g. `img[rr, cc] = 1`.

y, x : int

Starting position (row, column).

y2, x2 : int

End position (row, column).

Returns :

rr, cc : (N,) ndarray of int

Indices of pixels that belong to the line. May be used to directly index into an array, e.g. img[rr, cc] = 1.

polygon¶

skimage.draw.polygon()¶

Generate coordinates of pixels within polygon.

Parameters :

Parameters :	y : (N,) ndarray Y-coordinates of vertices of polygon. x : (N,) ndarray X-coordinates of vertices of polygon. shape : tuple, optional image shape which is used to determine maximum extents of output pixel coordinates. This is useful for polygons which exceed the image size. By default the full extents of the polygon are used.
Returns :	rr, cc : ndarray of int Pixel coordinates of polygon. May be used to directly index into an array, e.g. `img[rr, cc] = 1`.

y : (N,) ndarray

Y-coordinates of vertices of polygon.

x : (N,) ndarray

X-coordinates of vertices of polygon.

shape : tuple, optional

image shape which is used to determine maximum extents of output pixel coordinates. This is useful for polygons which exceed the image size. By default the full extents of the polygon are used.

Returns :

rr, cc : ndarray of int

Pixel coordinates of polygon. May be used to directly index into an array, e.g. img[rr, cc] = 1.
