I have ported it on android, but when I drag or zoom the map, It some times can
crash. And I have found the reason: the parameter y that pass into this
function makes the array (jumpTable8)[y][x] overstep the boundary. The status
of parameter y when it crash of each map I list below:
1. Atlas: when y is 675 it crash, position is line 87 in StackTile.cpp "return
(jumpTable8)[y][x];"
2. OpenStreetMap: y=256    line 89     return m_resultImage.color(
(jumpTable8)[y][x] );
3. Satellite View : y=675       line 92
4. Earth at Niget: y=675       line 92
5. Historical Map 1698: y=675 line 92
6. Precipitation(July): y=675      line 87
7. Precipitation(December): y=675  line 87
8. Temperature(December): y=675 line 87
9. Temperature(July): y=675 line 87

so, my question is: how can y be pass a 256 or 675 while the image height is
256 or 675.
