<td><p> use FCWin32::ConvertAlphaImageToHRGN to create HRGN from a 32bpp image.</p>
<p>This function determinate whether a point in region by test pixel's alpha value, if the pixel's alpha value == 0, the point outter of region, otherwise point in region. and the image's R-G-B channel be ignored</p>
