Subject: [Lcms-user] problem in
_cmsSaveProfileToMem
Hi Marti,
It seems to be a problem in the
function _cmsSaveProfileToMem. After saving profile into memory, the
profile handle would be changed. I got the segmentation fault, If I use it
after saving.
After the debug I found
the cause. Two new line shoulb be added in this function to avoid the profile
handle change.
BOOL LCMSEXPORT
_cmsSaveProfileToMem(cmsHPROFILE hProfile, void *MemPtr,
size_t* BytesNeeded)
{
LPLCMSICCPROFILE Icc =
(LPLCMSICCPROFILE) (LPSTR) hProfile;
LCMSICCPROFILE Keep;
CopyMemory(&Keep, Icc, sizeof(LCMSICCPROFILE));
_cmsSetSaveToMemory(Icc, NULL, 0);
//
Pass #1 does compute offsets
if (!SaveHeader(Icc)) return FALSE;
if (!SaveTagDirectory(Icc))
return FALSE;
if (!SaveTags(Icc)) return FALSE;
if (!MemPtr) {
// update BytesSaved so
caller knows how many bytes are needed for MemPtr
*BytesNeeded = Icc ->UsedSpace;
CopyMemory(Icc, &Keep,
sizeof(LCMSICCPROFILE));
--> add
this line
return TRUE;
}
if (*BytesNeeded < Icc
->UsedSpace) {
// need at least UsedSpace in MemPtr to
continue
CopyMemory(Icc,
&Keep, sizeof(LCMSICCPROFILE));
--> add this line
return FALSE;
}
_cmsSetSaveToMemory(Icc, MemPtr,
*BytesNeeded);
// Pass #2 does save to file into
supplied stream
if (!SaveHeader(Icc))
goto CleanUp;
if (!SaveTagDirectory(Icc)) goto CleanUp;
if (!SaveTags(Icc))
goto CleanUp;
// update BytesSaved so caller knows
how many bytes put into stream
*BytesNeeded = Icc ->UsedSpace;
Icc
->Close(Icc);
CopyMemory(Icc,
&Keep, sizeof(LCMSICCPROFILE));
return TRUE;
CleanUp:
Icc ->Close(Icc);
CopyMemory(Icc, &Keep, sizeof(LCMSICCPROFILE));
return FALSE;
}
Mit freundlichen
Grüßen
