Description: 该程序实现了对一幅图象进行Walsh变换。首先定义了一个imagewnd类, 该类可用于位图的创建、显示；WALh函数为快速沃尔什-哈达玛变换，f为时域值,F为变换域值,power为2的幂数，Walsh1函数为二维变换；在该函数中取出了一幅位图的所有像素，用来进行变换.具体算法过于专业，我就不细说了。-the realization of an image Walsh transform. First imagewnd definition of a category, such can be used for the bitmap is created, displayed; WALh function for the rapid Walsh-Hadamard transform, too-valued f, F value of the transform domain, power and the power to two the number Walsh1 function of two-dimensional transform; function in the removal of a bitmap of all pixels, used for transformation. specific algorithm is too professional, I will not elaborate on this.

Description: When I wrote this function my problem was to replace one color by an other on transparent bitmaps. My images were resources bitmaps, which I store in an ImageList for easy transparency.
There is no easy way to directly access a Bitmap s pixel on Win32. If you re interested in, this article may help you to understand the usage of CreateDIBSection.
If you have to load a bitmap from resource and made many color replacements, or if you have to change a color in a HBITMAP this function is for you.
If you have a bitmap in resource and want to replace one or more color on load, it s better to use CreateMappedBitmap. You can found in the sample program a ReplaceColor function which use CreateMappedBitmap.
I ve made the same code using only BitBlt. All BitBlt are really fast but the creation of the mask bitmap is so slow than the whole function is twice slower than the code using CreateDIBSection. ( sources are in the sample )
