I can't make any conclusions on what is wrong based on your input - could you provide pixel by pixel comparison: r, g, b,...r
Thank you for your reply. i check my pictures,they are right.i give you now.
If I have a problem with parameters or have some problems with steps.such as: pSrc, m_image.Step()
Can you give some specific conversion steps.
I don't know what are Cippimage, CreateImage, etc. I don't know how data types you use match to IPP data types. I don't know which image you would like to have in result from combining these 3 inputs (I've taken a look at them - from my point of view they have wrong size/step parameters in the bmp headers). Take a look at IPP manual, please.
