伪彩变换，我改变了调色板，可图象为什么没有变化啊，图象是用到了调色板板的，请高手指点(100分)

各位大侠，请出手啊，我快疯了

我知道了，BITMAP.PALLETE:=SELPALLETE 就可以了

我也很感兴趣，但看不懂，有几个地方你有错误：

1. CreateIdentityPalette 的第一参数为 HWND，但 image1.Picture.Bitmap.Handle 却是 HBITMAP；
2. SelectPalette 的第一个参数为 HDC，image1.Picture.Bitmap.Handle 却。。。
3. RealizePalette 也同样有错.

2.3. 两个地方应该为 Image1.Picture.Bitmap.Canvas.Handle,
1. 我就不知道了。。。。

请问如何调出调色板？用什么命令？

我也想知道.
