I recall that in order to be consistent we concluded that @200pct and @300pct
needed to be supported in addition to the @2x and @3x syntax.

Better, although it still does not document the supported set of scale
name extensions that we discussed/proposed off-line.

    Unify the HiDPI splash screen image naming convention

        The fix looks good to me.

        It would be better if a native speaker look at the
        documentation change in the launcher.properties file.


    That documentation seems to cover only *some* of the extensions we
    discussed.
    It ought to cite all of them if it does so at all. How else are
    people supposed
    to know what they can use ? Where else are you documenting it?
    Perhaps the launcher "man" page should be updated too
    find . -name java.1
    ./src/linux/doc/man/java.1
    ./src/linux/doc/man/ja/java.1
    ./src/bsd/doc/man/java.1
    ./src/bsd/doc/man/ja/java.1
    ./src/solaris/doc/sun/man/man1/java.1
    ./src/solaris/doc/sun/man/man1/ja/java.1

    .. although I think there is also some HTML version maintained by
    the pubs/docs team
    that is not in OpenJDK - the above does not include Windows or Mac.
    I don't know offhand what is recommended these days. We'll have to
    find someone
    who does more with the launcher to help point to where to do the
    documentation.

    And the doc does not really explain what is going on here. Reading
    that I might
    think I am supposed to pass -splash:im...@2x.ext if I want a
    hi-dpi image
    and that is not the idea at all, is it ?
    The idea is you would still specify -splash:image.ext and the
    *implementation*
    will look for the most appropriate scaled image for the current
    desktop.

    I think we should also have a CCC cover this (somehow).

            <http://cr.openjdk.java.net/%7Erchamyal/8151787/webrev.01/>

            Updates :

            1)Updated the consition as suggested  if(*scaleFactor -
            (int)*scaleFactor < 0.000001)

            2)Includes the changes of
            src/java.desktop/unix/native/libsplashscreen/splashscreen_sys.c

            3)+        //map the splash co-ordinates as per system scale
            +        splash->x /= splash->scaleFactor;
            +        splash->y /= splash->scaleFactor;



            This change is required only for windows and linux. As we
            use absolute system resolution for centring the splash on
            screen on these.

            i.e. if system resolution is 1920 X 1080(i.e. unscaled
            resolution) on windows and linux we use this for centring
            the splash on screen. For mac scaled resolution is used
            directly.

                    Bug: https://bugs.openjdk.java.net/browse/JDK-8151787

                    Webrev:
                    http://cr.openjdk.java.net/~rchamyal/8151787/webrev.00/

                    Issue: Currently different naming conventions are
                    used for Hidpi image on different platforms.

                    With this change the names will be unified across
                    all platforms.

                    For a unscaled image image.ext following naming
                    convention will be followed.

                    Unscaled name: image.ext

                    Supported Scaled Names:

                    If screen scale is integer number e.g. 2:
                    im...@2x.ext <mailto:im...@2x.ext>

                    If screen scale is float value like 1.25:
                    im...@125pct.ext <mailto:im...@125pct.ext>


                The fix should be reviewed on the awt-dev alias.

                + if(*scaleFactor - (int)*scaleFactor < 0.000001)

                Should there be so high precision there? Could only
                percent values be compared like
                 if ((*scaleFactor *100) != ((int)(*scaleFactor)) * 100)


                +        //map the splash co-ordinates as per system scale
                +        splash->x /= splash->scaleFactor;
                +        splash->y /= splash->scaleFactor;

                It looks like the splash coordinates and sizes are
                rescaled in different places. Is it possible to do
                that in the same place? May be in
                java_awt_SplashScreen.c file getBounds() function?


            src/java.desktop/unix/native/libsplashscreen/splashscreen_sys.c
                   *scaleFactor = getNativeScaleFactor();

            Could you also include the change which requires to add
            some default output screen name to the
            getNativeScaleFactor() function on Linux. There is the
            discussion about that:
