    Default New WebP format

    Just a note... looks like Google has created a new, supposedly better, format for images called WebP.

    http://code.google.com/speed/webp/index.html

    Would be great to add this to your supported images... which I am sure you will.

    Cheers!

    Why? Just because Google published an incomplete standard?
    They have to do a better job than just announcing something.
    An image format w/o alpha support which needs a video library to decode it.
    Sorry but I don't think that people need this in the next two years.

    Make that ten years. Anyone seen JP2 on the web yet? APNG? MPNG?

    Hhmm, ... I think the WebP format will get substantial importance!
    Just because the internet giant Google make large efforts toward the introduction of this format!

    for the new WebP Format (from Google) see:
    "Google code", "The Chromium Blog (in english)", "Wikipedia (in english)", "techreport (in english)", "Gizmodo (in english)", "creativebits (in english)", "Wikipedia (in german)", "heise online (in german)", "OnSoftwareBlog (in german)", ...

    Thats why I suggest to support this format as fast as possible!

    The latest version of Opera 11.1 already supports WebP format and makes use of it in Opera Turbo (useful for dial-up connections), so maybe it won't be so long before we see it used more widely. Implenenting support in IrfanView would encourage its use, but it still depends on web masters to make use of the new format — that takes time and costs money.

    I guess it will be the same just like with Microsoft's xps format. A format against adobe's pdf.

    You can create xps files with an inbuild Microsoft print driver, xps plugin - but who does really need it + use it frequently?

    Let's see how webp will be distributed on the internet, on websites; then we can create plugins + support it in IrfanView

    I also don't see any advantage in developing a new "lossy" format - because the main "speed" problem nowadays is certainly not "big" pictures on webpages, it's more the use of java scripts and ads, which makes a website longer to load!

    Main point: Irfanview is an image viewer so that is why it should include the webp format.

    Off-topic: Their statistics say
    In a large scale study of 900,000 web images, WebP images were 39.8% smaller than jpeg images of similar quality.
    It's suported by Chrome and Opera so i'm thinking it's gonna hit Firefox till the end of the year. For Internet Explorer we should wait at least 2-3 years before they publish a beta that supports this (for the curious search the net for: "transparent png and internet explorer")

    I would love to see IrfanView load and save WebP images.

    Since Google provides the libraries and example code, I would expect the loading to be pretty straightforward, and the saving to just follow the JPEG quality UI with maybe additional controls for sharpness and target file size.

    As a workaround, I use Opera/Chrome to open WebP files. To save as WebP a batch script set in Irfanview as the first external editor:

    Quote Originally Posted by SaveAsWebP.bat
    @echo off
    if "%~1" == "" (
    echo.
    echo Converts an image file [JPEG, TIFF, GIF, PNG, BMP, JPEG XR or ICO] into the .WebP format using Google's cwebp encoder [webp.googlecode.com/files/libwebp-0.1.2-windows.zip]
    echo.
    echo Usage: %0 \path\imagefilename
    echo creates a new \path\imagefilename.webp
    goto :eof
    )

    set TempResultName=%2
    if "%~2" == "" (
    set TempResultName=%~dpn1.webp
    )

    echo converting "%~f1" to "%TempResultName%" ...
    "c:\Program Files\WebP\cwebp.exe" "%~f1" -q 80 -o "%TempResultName%"
    echo.
    The script is set up in IrfanView's Options -> Properties/Settings -> Miscellaneous -> Set external editors -> Browse and it's used from File -> Open with external editor (Shift+E if you list it first). It will create a WebP image with a quality index of 80 in the same folder (so it won't work for clipboard images nor files in read-only locations).

    The script obviously needs the prerequisite encoder saved in the specified path (feel free to change \Program Files\WebP\) .
