Maybe this has something to do with with mipMapping/smooth? It looks like it's not anti-aliasing?

Mitch,

 

Thanks for your reply. 

 

You are right. I’m not playing all the cards…

 

Original image attached (it is white over transparent so you will not see it in the email body. The file is called isotope.png) 

 

The item who renders this is the following:

 

import QtQuick 2.4

 

Item {

    id: root

    implicitWidth: 100

    implicitHeight: 100

 

    property real padding: 0

    property alias imageSource: icon.source

    property color imageColor: controller.settings.foregroundColor

 

    Image {

        id: icon

        anchors.fill: parent

        anchors.margins: root.padding

        fillMode: Image.PreserveAspectFit

    }

 

    ColorOverlay {

        id: overlay

        source: icon

        anchors.fill: icon

        color: root.imageColor

    }

}

Can you elaborate on “really bad”, and also share a screenshot?

Hi,

 

I have a simple question. 

 

How to render small Images decently on non retina displays with QtQuick?

 

In my apps, I use images for icons and logos. They are all big enough to be displayed correctly. 

 

However, on non Retina displays they get really bad! And on retine display they appear perfectly. 

 

What is the rule of thumb to use QtQuick Image element on on retina displays?

 

Thx!

 

Regards,

 

Nuno
