C Specification

#include <nitro/gx/g2.h>

void G2S_SetBG2Affine(
    const MtxFx22 * mtx,
    int centerX,
    int centerY,
    int x1,
    int y1
);

Description

Arguments

mtx Pointer to the transformation matrix
centerX x-coordinate component of the center of rotation
centerY y-coordinate component of the center of rotation
x1 x-coordinate component prior to rotation
y1 y-coordinate component prior to rotation

Return Values
