|
| - * This file provides code to read and write International Color Consortium
|
| - * (ICC) device profiles embedded in JFIF JPEG image files. The ICC has
|
| - * defined a standard format for including such data in JPEG "APP2" markers.
|
| - * The code given here does not know anything about the internal structure
|
| - * of the ICC profile data; it just knows how to put the profile data into
|
| - * a JPEG file being written, or get it back out when reading.
|
| - *
|
| - * This code depends on new features added to the IJG JPEG library as of
|
| - * IJG release 6b; it will not compile or work with older IJG versions.
|
| - *
|
| - * NOTE: this code would need surgery to work on 16-bit-int machines
|
| - * with ICC profiles exceeding 64K bytes in size. If you need to do that,
|
| - * change all the "unsigned int" variables to "INT32". You'll also need
|
| - * to find a malloc() replacement that can allocate more than 64K.

|
| - * (64K), we need provisions to split it into multiple markers. The format
|
| - * defined by the ICC specifies one or more APP2 markers containing the
|
| - * following data:
|
| - * Identifying string ASCII "ICC_PROFILE\0" (12 bytes)
|
| - * Marker sequence number 1 for first APP2, 2 for next, etc (1 byte)
|
| - * Number of markers Total number of APP2's used (1 byte)
|
| - * Profile data (remainder of APP2 data)
|
