DrawDib StretchDIBits which one is faster?

Question

I've never used DrawDib APIs, My Application's UI rendering is based on stretchDIBits. Because there are really lots of large images to draw , the stretchDIBits's (HAFTONE is used to get better render result) performace is bad...

I heard about DrawDib is a group of efficient APIs to draw DIBs to DC. Is it better than stretchDIBits?

Can anyone give me some comparision document of them? If the question is stupid, I am sorry. I really have very little experience about this.

Thanks in advance.

Collectively, the DrawDib functions are similar to the StretchDIBits function in that they provide image-stretching and dithering capabilities. However, the DrawDib functions support image decompression, data-streaming, and a greater number of display adapters.

You will find it beneficial to use the DrawDib functions in some circumstances. Still, StretchDIBits is more diverse than the DrawDib functions and should be used when the DrawDib functions cannot provide the desired functionality. The following list describes factors to consider when deciding whether to use the DrawDib functions or StretchDIBits.
