KDE splash screen picture size change

Question

I would like to change my splash screen image in KDE/PLASMA.

I made a custom theme, and changed the picture located in

/usr/share/plasma/look-and-feel/org.kde.my_theme.desktop/contents/splash/images/kde.svgz

I would like to change the size of the picture though. This should be controlled in the file:

/usr/share/plasma/look-and-feel/org.kde.arch_custom.desktop/contents/splash/Splash.qml

which reads

Rectangle {
    id: topRect
     width:  parent.width
     height: (root.height / 3) - bottomRect.height - 1
    y: root.height
    color: "#4C000000"
    Image {
        source: "images/kde.svgz"
        anchors.centerIn: parent
        sourceSize.height: 128
        sourceSize.width: 128
    }
}

I have tried to edit different parts of this, but the picture is always the same. What should I edit to change the splash image size?

Answer 1

In case you (or people following the search result) were in fact trying to change the background image, check the source code for custom themes (some at kde store)

Basically you just need to replace [the top level / root element in Splash.qml]

Rectangle {
    id: root
    color: "black"

[as it is in the current default Fedora theme for instance]

with

Image {
    id: root
    source: "images/background.png"

Placing an appropriate background image in the specified location
