Loading of 1-bit images

Dear Sirs,
I have to manage (e.g. load) images having
depth of 1 bit.
Is it possible to do that with IppiMalloc_8u_C1 or does it exist something
specific ?
Thanks and regards

Thank you very much for your answer Ross.
For the second question, I was born and I live in Genoa, very nice town in Northern Italy on the sea.
I think that at this time it's not easy to find employments on embedded systems and so on in my town, but I think that in Milan you could find it easier.
Regards.

Hi,
IPP does not have functions to work with 1u images directly. Instead of that we propose you to convert 1u image to 8u image (there are special functions in IPP to do that) and after converting it you can use any IPP functions wich work with 8u data.

Hi Vladimir and thank you for your answer.
I effectively tried to use IppiMalloc_8u_C1R
and then IppiConvert_1u8u_C1R but it seems
not working.
Perhaps I do wrongly use the "steps" in the IppiConvert
procedure ...
Could you help me in this ?
Thank you again

Well,
at least, I can try:)
In IPP, the step parameter is always in bytes. It specifies number of bytes between adjacent lines in image. For example, for image with width 9x3 bits step should be 2 if there is no any padding bytes at the end of line.

Vladimir
