size_t bytesPerLine = (dst.getWidth() * dst.getBytesPerPixel());
size_t offset = bytesPerLine * _offset;

dst[i + 0] = ofClamp(255*src[offset + i + 0], 0, 255);
dst[i + 1] = ofClamp(255*src[offset + i + 1], 0, 255);
dst[i + 2] = ofClamp(255*src[offset + i + 2], 0, 255);
}
for(int l = dst.getHeight()-1; l >= 1; l--) {
memcpy(&dst[l*bytesPerLine], &dst[(l-1)*bytesPerLine], bytesPerLine);
