Method

GeglMatrix3originate

Declaration [src] 

void
gegl_matrix3_originate (
  GeglMatrix3* matrix,
  gdouble x,
  gdouble y
)

Description [src]

Shift the origin of the transformation specified by matrix to (x, y). In other words, calculate the matrix that:

  1. Translates the input by (-x, -y).

  2. Transforms the result using the original matrix.

  3. Translates the result by (x, y).

Parameters

x

Type: gdouble

X coordinate of new origin.

y

Type: gdouble

Y coordinate of new origin.
