Class API
- class Point
- __init__(self)
- __init__(self, x, y)
- __init__(self, point)
- __init__(self, sequence)
Overloaded constructors.
Without parameters, Point(0, 0) will be created.
With another point specified, a new copy will be created, “sequence” is a Python sequence of 2 numbers (see Using Python Sequences as Arguments in PyMuPDF).
- Parameters
x (float) – x coordinate of the point
y (float) – y coordinate of the point
- distance_to(x[, unit])
Calculate the distance to x, which may be
point_like
orrect_like
. The distance is given in units of either pixels (default), inches, centimeters or millimeters.- Parameters
x (point_like,rect_like) – to which to compute the distance.
unit (str) – the unit to be measured in. One of “px”, “in”, “cm”, “mm”.
- Return type
float
- Returns
the distance to x. If this is
rect_like
, then the distanceis the length of the shortest line connecting to one of the rectangle sides
is calculated to the finite version of it
is zero if it contains the point
- norm()
New in version 1.16.0
Return the Euclidean norm (the length) of the point as a vector. Equals result of function abs().
- transform(m)
Apply a matrix to the point and replace it with the result.
- Parameters
m (matrix_like) – The matrix to be applied.
- Return type
- unit
Result of dividing each coordinate by norm(point), the distance of the point to (0,0). This is a vector of length 1 pointing in the same direction as the point does. Its x, resp. y values are equal to the cosine, resp. sine of the angle this vector (and the point itself) has with the x axis.
- Type
- x
The x coordinate
- Type
float
- y
The y coordinate
- Type
float
Note
This class adheres to the Python sequence protocol, so components can be accessed via their index, too. Also refer to Using Python Sequences as Arguments in PyMuPDF.
Rectangles can be used with arithmetic operators – see chapter Operator Algebra for Geometry Objects.
