    Default Searching for ILDA file format specification for format codes 4 and 5

    If you have a copy of the ILDA file format specification for format codes 4 and 5, I would appreciate it if you could send me a copy. Best regards, weartronics

    I don't know about a copy of the standard (which has all sorts of copyright issues), but Zilda has a format 4 and 5 loader that is fairly straight forward to follow if you know C++ and QT.

    Source is available from google code, and if you are prepared to ship under GPL3 you could lift it wholesale, otherwise a rewrite is not exactly hard.

    Regards, Dan.

    Thanks for the tip about Zilda, I wasn't aware of this software until now.

    Truth be told, I already reverse-engineered formats 4 and 5 based on the files I needed to read and header similarities with the earlier format codes. But I really want to check compliance against the standard, not just one particular implementation.

    What is the reasoning behind the unpublished standard, hidden from non-members? This really discourages acceptance and invites broken implementations.

    Yea, going to the standard helps avoiding propagation of bugs into multiple implementations.

    I would note that there has already been at least one implementation of 4/5 that got the order of the colour bytes backward compared to the standard.

    Regards, Dan.

    OK, I was able to get a copy of the standard, thank you.
