IrfanView Comments data - bug?

Discussion in 'Digital Photography' started by Terry Pinnell, Feb 10, 2012.

  1. I'd appreciate others trying to reproduce this please. Not sure if it's my
    misunderstanding or a minor bug.

    A handy feature is that in a JPG Comment you can enter things like $F to
    get the filename and $E306 for the EXIF Date/Time.

    But if I try to place both on the same line, e.g.

    $F EXIF Date/Time = $E306

    then it fails, displaying just the raw codes.

    Sigh, each goes on a separate line.

    On an associated point, any of these codes that generate the '\'
    character, such as $D for the full file path, result in duplicated
    slashes, '\\'. For example, results like
    C:\\Docs\\My Pictures\\PHOTOS\\Walks UK\\TP04\\TP04-Day3\\

    Bug or by design?

    No need for the sigh - especially as you're mistaken. Both codes *can* go
    on the same line.

    It was my own stupid mistake. I must have forgotten to
    perform the Write command before examining the result.

    A consequence of Irfanview's Unix roots, most likely. Pretty universally in
    Unix, the backslash is a quoting character and must be doubled if an actual
    backslash is intended. Some Windows programs recognize this and are somewhat
    forgiving of inappropriate doubled backslashes. Most aren't.

    IrfanView is a pure Windows program:

    The double-backslash requirement may be a function of using the C
    language.

    Thanks, duly joined for future use. (With great difficulty registering!
    Gave up on the ambiguous images after 3 failed attempts and tried an MP3.
    Eventually succeeded. A few forums go way OTT on this stuff IMO.)
