Unsolved Font rendered in Linux Ubuntu 18.04 is not same as Embedded Linux
-
Hi,
I am using Qt5.6.3,
I have Qt/QML Application, in which I have loaded the Qt Font as below
My Application must run on platforms: Windows, Windows CE, Ubuntu 18.04 and Embeded Linux(built using Buildroot)In Application, I am loading Font as below
QFont arialFont("Arial Unicode MS", 15); QGuiApplication::setFont(arialFont);
In QML, I show a text as below
Text { id: txt font.pointSize:10 color: "#1E1E1E" elide: Text.ElideRight horizontalAlignment: Text.AlignHCenter text: "Start Apt" }
The text is elided(looks different) in embedded Linux platform when compared with Ubuntu Linux desktop(18.04).
I managed to match fonts in windows with Ubuntu Linux desktop. By explicitly using freetype font engine in windows desktop.(modifying qt.conf)
Free type is used in Linux for font rendering and Qt is configured for system freetype. I used different freetype versions(2.9.1, 2.6.1, 2.5.3 and 2.3.12) and didn't see much variation.
I also gathered font information by logging them.
Values of font properties that are logged and are same in all platforms:
Text Width: 52 Font Point size: 10 Font Family: Arial Unicode MS Font Pixel size: 13 Font letter spacing: 0 Font Weight: QFont:: Normal-50 Font Ratio: 1 Hinting Preference: PreferDefaultHinting Capitalization: Capitalize SpacingType: PercentageSpacing Stretch: Unstretched Style: Normal StyleHint: AnyStyle StyleStrategy: PreferDefault Weight: Normal
Only below property is different
Text Painted Width: 48.35 in Linux Ubuntu and 47.39 in embedded Linux
Below picture shows the difference:
Left side is Ubuntu Linux Desktop(18.04) and right is Embedded Linux
Is there any way I can make fonts looks similar in all platforms?
