Attributes

params : (3, 3) array

Homogeneous transformation matrix.

Has the following form:

X = a0*x + a1*y + a2 =
  = sx*x*cos(rotation) - sy*y*sin(rotation + shear) + a2

Y = b0*x + b1*y + b2 =
  = sx*x*sin(rotation) + sy*y*cos(rotation + shear) + b2

where sx and sy are scale factors in the x and y directions, and the homogeneous transformation matrix is:

[[a0  a1  a2]
 [b0  b1  b2]
 [0   0    1]]

Parameters

matrix : (3, 3) array, optional

Homogeneous transformation matrix.

scale : {s as float or (sx, sy) as array, list or tuple}, optional

Scale factor(s). If a single value, it will be assigned to both sx and sy.

rotation : float, optional

Rotation angle in counter-clockwise direction as radians.

shear : float, optional

Shear angle in counter-clockwise direction as radians.

translation : (tx, ty) as array, list or tuple, optional

Translation parameters.

2D affine transformation.

Local connectivity graph

Hover to see nodes names; edges to Self not shown, Caped at 50 nodes.

Using a canvas is more power efficient and can get hundred of nodes ; but does not allow hyperlinks; , arrows or text (beyond on hover)

SVG is more flexible but power hungry; and does not scale well to 50 + nodes.

All aboves nodes referred to, (or are referred from) current nodes; Edges from Self to other have been omitted (or all nodes would be connected to the central node "self" which is not useful). Nodes are colored by the library they belong to, and scaled with the number of references pointing them
