［求助］关于API（bitblt）
Private Declare Function BitBlt Lib "gdi32" (ByVal hDestDC As Long, ByVal x As Long, ByVal y As Long, ByVal nWidth As Long, ByVal nHeight As Long, ByVal hSrcDC As Long, ByVal xSrc As Long, ByVal ySrc As Long, ByVal dwRop As Long) As Long......
......
For i = 0 To 2
Value(i) = Int(Rnd * 6)
BitBlt picValue(i).hDC, 0, 0, 32, 32, Picture1.hDC, Value(i) * 32, 0, vbSrcCopy
Next
......
......
前面过程我省略了，大体意思就是将 Picture1的图片随机切割６分，分到３个数组控件picValue中．
但是我不明白的事就是图片的实际width是2880，height是480，而函数中红色部分是32的大小切割，
我不明白bitblt函数中分割方式是以什么为单位的，请高手指教下，谢谢！
