Thread: New WebP format

  1. #11

    Default

    If it takes a vote, I would like to see support for webp format in some form.
    While full support would be nice, if we can only load it and save as PNG it would serve my purposes.
    As a plugin, of course.

    maybe a little off-topic: The method used by google to test their format is apparantely a little flawed. So they retested. Guess what: it still works just fine! Maybe i'm being subjective here but, although 25%-34% is less than 39%, it's still at least 25% better than JPEG.

    Probably the best argument i can give for the wide support of WebP is file size and how it matters nowadays in an increasingly mobile enviroment. I don't know the prices for other countries but in Romania mobile internet is not that cheap and it has data caps. And if you're not concerned about the financial aspect think about the increase in speed: a crowded 3G cell is not the same as WiFi; and also WiFi is not the same as a good cable connection.

    Here's google's conclusion:
    The study evaluated WebP compression in comparison to JPEG. We observed that the average WebP file size is 25% - 34% smaller compared to JPEG file size at equivalent SSIM index. The SSIM vs bpp plots showed that WebP consistently required less bits per pixel than JPEG for the same SSIM index. These results indicate that WebP can provide significant compression improvements over JPEG.

    I think the big difference between jp2 and webp is that the latter is supposed to be free to use, free to batch convert.
    If it hurts not to drint, don't waste the bottle then.

    I have forwarded this feature request to Irfan. Let's see what he says about it.

    The reply was just as I expected. He is not too willing to add it until it is widely used.
    Yes, I can add it, but I assume this format will be the same death-end like JPG-2000 or HDP/WDP
    Maybe not ... but I never saw a website using it ... I can add it later, when it is really used, more widely.

    => I don't like hypes, I already added many formats just because of useless hypes

    As individual solution? No!
    Only Irfan Skiljan decides whether a new format will be supported or not ...

    Default Support for the new image format from Google: webP?

    Hi,
    Do you have any plans for adding support for loading and saving in the new Google image format - webP ? (http://code.google.com/intl/da-DK/sp...ocs/using.html)

    Google just anounced new extentions to their WebP format: WebP-lossless und WebP-lossy-alpha as a substituion für PNG for example.

    read here http://code.google.com/intl/de-DE/sp...pha_study.html

    so the story goes on.

    Gazing in my crystal ball I see a "weppy" WebP PlugIn for IrfanView.
