Private Type ColorChart

ColorCount(255) As Long '统计原来图片中的亮度出现次数 PixcelCount As Long '记录图片的像素个数

ColRatio(255) As Single '记录每一个亮度的出现比例 NewVal(255) As Byte '存放新的亮度索引 End Type

Dim Gray As Integer Dim X As Long Dim Y As Long Dim I As Long Dim L As Long Dim M As Long Dim C As Double

Done = False

TimeFilter = timeGetTime With ColChart

For X = 0 To 255 '先把数组清零 .ColorCount(X) = 0 Next

For X = 0 To OutPutWid '这两个循环用来扫描图片数据，记录每个点的灰度和出现次数

For Y = 0 To OutPutHei
