Detailed Description
Functions to handle profiles.
Function Documentation
check an file if it is a profile
- Parameters:
-
filename | the filename to check |
coloursig | colour space signature as described in the ICC specification |
- Returns:
- true/false
check an memory block if it is a profile
- Parameters:
-
mem | the memory containing the profile |
size | the size of the memory block |
coloursig | currently ignored |
- Returns:
- true/false
Find out where in the Oyranos search path the specified profile resides.
- Deprecated:
- This function will be substituded by oyProfile_GetFileName.
- Parameters:
-
profile_name | the filename find in the Oyranos search path |
allocate_func | user provided function for allocating the string memory |
- Returns:
- the path name where the profile was found in the Oyranos search path

obtain an memory block in the responsibility of the user
Please note the size parameter is sensible. Eighter set it to zero or to the size obtained with oyGetProfileSize to get the full data or specify the size you want to get a partitial profile.
This feature is useful for instance to get only the headers of many profiles.
- Parameters:
-
| profilename | specifies the profile |
[in] | size | desired size, or zero for a complete copy |
[out] | size | the size of the returned block |
| allocate_func | the users memory allocation function |
- Returns:
- the profile block in memory allocated by oyAlloc_f
get the profiles size
- Parameters:
-
profilename | specifies the profile |
- Returns:
- size

calculate a md5 digest beginning after the header offset
The md5 implementation is written by L. Peter Deutsch
- Parameters:
-
[in] | buffer | complete profiles buffer |
[in] | size | over all profile size |
[out] | md5_return | buffer to write in the md5 digest (128 bytes) |
- Returns:
- -1 wrong profile_id detected, 0 - good, 1 - error
-
