程序代码：

Private Sub Command6_Click() '旋转图像
Dim srcWidth, srcHeight, i, j
Picture1.ScaleMode = 3 '设置坐标度量单位为像素
Picture2.ScaleMode = 3
srcWidth = Picture1.ScaleWidth
srcHeight = Picture1.ScaleHeight
Picture2.Picture = LoadPicture("") '清除原有图片
For i = 0 To srcWidth - 1 '按宽度循环扫描
    For j = 0 To srcHeight - 1 '按高度循环扫描
        Picture2.PaintPicture Picture1.Picture, j, i, 1, 1, i, j, 1, 1, vbSrcCopy
