m_NumFramesX = m_pImage->w (191) / m_FrameWidth (47) = 4; 
m_NumFramesY = m_pImage->h (256) / m_FrameHeight(64) = 4;
TotalFrames = m_NumFramesX(4) * m_NumFramesY(4) = 16;

Source code

-> Zeile und Spalte aus dem Frameindex Berechnen:
spalte = fFrameNumber(6)%m_NumFramesX(4) = 2(Rest);
zeile = fFrameNumber(6)/m_NumFramesY(4) = 1;

x = 2*47 = 94px;
