Detailed Description
EDID data block parsing.
The purpouse of this API is to obtain basic and displayable device
identification strings and colorimetric informations contained in the
EDID data block sent by monitors.
The user has to pass in a valid EDID block. This can be obtained per a
root window X atom or a XRandR output property and is not part of this
API. The data block is passed to XcmEdidParse(). This function
generates a list of key value pairs, with some first rough
interpretation. The key/values are useable for data bases, ICC profile
generation or device identification. The returned XcmEdidKeyValue_s
list elements can be individually read and worked with. Please look as
well on the XcmEdidPrintString() function and examples/edid-parse/ as a
small example on how to use the API. The XcmEdidPrintOpenIccJSON() will
pull out a JSON data structure. XcmEdidFree() releases allocated list
memory.
