Now I feel really dumb! This is a function I added to the lcms1 source. It
returns the FILEMEM's stream->Block and Size. I'll explain why we need this and
see if there might be some other way to do this. We have c++ class that
contains a cmsHPROFILE. Its copy ctor needs to open a copy of the profile
contained in the "from" instance. In order to do this, we need to know if the
profile is file-based or mem-based. This is how I'm doing this now:
if(((_cmsICCPROFILE*)from.m_lcmsProf)->IOhandler->PhysicalFile[0])
m_lcmsProf =
cmsOpenProfileFromFile(((_cmsICCPROFILE*)from.m_lcmsProf)->IOhandler->PhysicalFile,
"r");
else {
/*DWORD syz;
LPVOID mem = cmsGetMemBasedPointerAndSize(m_lcmsProf,
&syz);*/
FILEMEM* fm =
(FILEMEM*)((_cmsICCPROFILE*)from.m_lcmsProf)->IOhandler->stream;
DWORD syz = fm->Size;
LPVOID mem = fm->Block;
m_lcmsProf = cmsOpenProfileFromMem(mem, syz); // Copies mem to new ptr.
}
Although I can't do this, of course, because FILEMEM is not exposed to the
outside world. Is there some way to open a profile given an existing profile?
Something like:
m_lcmsProf = cmsOpenProfileFromProfile(cmsHPROFILE);
It would inspect its private fields to see if it's file-based, mem-based,
whatever, and open it accordingly.
