void SkMatrix44::asRowMajord(double dst[]) const {
    const SkMScalar* src = &fMat[0][0];
    for (int i = 0; i < 4; ++i) {
        dst[0] = SkMScalarToDouble(src[0]);

        dst[12] = SkMScalarToDouble(src[3]);
        src += 4;
        dst += 1;
    }
}

Example #2

void SkMatrix44::setRowMajord(const double src[]) {
    SkMScalar* dst = &fMat[0][0];
    for (int i = 0; i < 4; ++i) {
        dst[0] = SkMScalarToDouble(src[0]);

        src += 4;
        dst += 1;
    }
}

Example #3

    const SkMScalar* src = &fMat[0][0];
#ifdef SK_MSCALAR_IS_DOUBLE
    memcpy(dst, src, 16 * sizeof(double));
#else
    for (int i = 0; i < 16; ++i) {
        dst[i] = SkMScalarToDouble(src[i]);
