G2_SetBG3Affine


C Specification

#include <nitro/gx/g2.h>

void G2_SetBG3Affine(
    const MtxFx22 * mtx,
    int centerX,
    int centerY,
    int x1,
    int y1
);

Description

This function sets the BG3 affine transformation. The point (x2, y2) after affine transformation is obtained with the following formula:

Arguments

mtx Conversion matrix
centerX x-component of the coordinates of the center of rotation
centerY y-component of the coordinates of the center of rotation
x1 x-component of the coordinates before rotation
y1 y-component of the coordinates before rotation

Return Values

None
