    Updating media properties on upload.

    I'm intercepting image uploads to resize images to a maximum size. Easy-peasy except...

    I can't seem to get the IMedia properties to update.

    // Tap into the Saving event
MediaService.Saving += (sender, args) =>
{
    // Resize code removed for brevity. It works.

    // Set the correct meta values for the image.
    media.SetValue(Constants.Conventions.Media.Width, newWidth);
    media.SetValue(Constants.Conventions.Media.Height, newHeight);
    media.SetValue(Constants.Conventions.Media.Bytes, bytes);
    sender.Save(media, 0, false);
}

    Am I saving those values at the wrong time?

    I hope your not doing GetById to get the media item else your writing to it before it's saving so it will then not save anything.

    In other words: show your var media = ... something ? :)

    Nah... I'm looping through the args.SavedEntities enumerable. Basically an enhanced version of the preprocessing example here. http://24days.in/umbraco/2014/all-your-images-are-belong-to-umbraco/

    Could it be that your "saving" event happens before the core code sets the same properties?

    EDIT: My sample was a false positive! Refreshing the media revealed that it was in fact not saved, just modified for display.

    Fixed sample:

    MediaService.Saved += (sender, e) =>
{
    foreach (IMedia entity in e.SavedEntities)
    {
        entity.SetValue(Constants.Conventions.Media.Width, 8878);
        sender.Save(entity, 0, false);
    }
};

    The above seems to work.

    Yeah that get's it Morten thanks. I thought it was probably a timing issue.

    Morten Christensen reckons this is the probable cause of my issue.
