I have an image in memorythat is sourced inaRGB format and I need use some of the functionality in IPP. However, I do not see an efficient way to covert between aRGB of my imageto RGB0 formatused by IPPwithout exporting from my aRGB image to a file and then re-importing into IPP.
After looking at the help files for IPP, there does not seem to be another way to do it. Are there any suggestions?
That looks like I might be able to get it to work, but it I'm not sure. I'm not understanding the documentation well.
However, you gave me an idea to wonder if I could do this with a shift. After downloading another help file, I found ippsLShiftC_32s_I function. If I run this shift 32bits left for 8 bits, I should get the pattern I need.
Thnaks for suggestion.
Use ippiCopy_8u_AC4C3R, refer to ippiman.pdf, refer to Image Data Exchange and Initialization Functions
