VB图像的锐化操作一例，图像锐化效果在PhotoShop中经常用到，可把图片变清淅，但锐化过度也是不好的。简单说下本程序实现的原理：获得Picture1中指定点(x0,y0)的R、G、B分量值，获得Picture1中与(x0,y0)点相邻的点的R、G、B分量值，计算锐化后的R、G、B分量值，画出锐化后的(x0,y0)-VB image sharpening operation one case, image sharpening effect is often used in PhotoShop, you can put the picture becomes clear mission, but excessive sharpening is not good. Simply put the program under the principles of: obtaining Picture1 specified point (x0, y0) of R, G, B component values ​ ​ obtained Picture1 with (x0, y0) point adjacent point R, G, B component value calculating the sharpened R, G, B component value, draw sharpened (x0, y0)
