Ok I've solved it. It was my fault, the -r parameter must have a list of Qt Resource files.. I got a bit confused with the fonts/ path, I though it was a folder but it's a prefix path a Qt Resource file (.qrc): <RCC> <qresource prefix="/fonts"> <file>MyFont.TTF</file> </qresource> </RCC> and the command: binarycreator -c config\config.xml -p packages -r resources/rc.qrc MyAppSetup.exe

@artwaw said in Blurry and strange color when creating barcode using fonts: @Proton-Phoenix I no longer have access to the Zebra I was using in the past (I changed the company since then). Zebra printers are a story on their own to troubleshoot anyway... General approach I used: make sure the printer is configured properly in the system, with the default page size set to the target page size. query the QPrinterInfo instance for the default page size. use that data with QPdfWriter to render whatever text + barcode I need. remember DPI settings, either set what the manual for the printer says (ideal) or 300 (this didn't end well for Dymo printers I used for a while, needed exact DPI of 204 ;) ). print and enjoy. In general getting this to work might be lots of trial and error, depending on the brand and drivers. But once it's done right it is literally zero maintenance for years. <3 Thank you bro for everything <3

something like this. Try it out QFont font("Courier New"); font.setStyleHint(QFont::Monospace); QApplication::setFont(font); or QCoreApplication::setFont(font);

I fixed this by setting QFont font = this->font(); to ui->appName->font(); in case anyone comes across this.

@JKSH Now looks like very similar. Thanks everyone for help :)

This is how we are sizing and centering text of variable size: Text { text: sometext width: somewidth height: someheight font.pointSize: 25 minimumPointSize: 2 fontSizeMode: Text.Fit horizontalAlignment: Text.AlignHCenter verticalAlignment: Text.AlignVCenter }

When you don't want to let save it by Qt you have to read the font attributes one by one from your ini file and then construct it with the QFont ctor

I've tried this but it only scales the first character for some reason, and after I stop scaling the font size returns to normal value = 0.3; // random value that increases the font size every time this part of the program is called for(int i = -1; i < textEdit->toPlainText().length() - 1; i++) { QTextCursor cursor = textEdit->textCursor(); cursor.setPosition(QTextCursor::Start + i, QTextCursor::MoveAnchor); // for some reason the first letter is start - 1 (start might be 1 and programming languages usually start counting at 0) cursor.setPosition(QTextCursor::Start + (i + 1), QTextCursor::KeepAnchor); // next position and keep anchor to highlight cursor.charFormat().font().setPointSize(cursor.charFormat().font().pointSize()*(value+1)); QTextCharFormat fmt; // resized but don't work fmt.setFontPointSize(cursor.charFormat().font().pointSize()*(value+1)); mergeFormatOnWordOrSelection(fmt); // resized and this works } void MainWindow::mergeFormatOnWordOrSelection(const QTextCharFormat &format) { QTextCursor cursor = textEdit->textCursor(); if (!cursor.hasSelection()) cursor.movePosition(QTextCursor::NextCharacter, QTextCursor::KeepAnchor); cursor.mergeCharFormat(format); textEdit->mergeCurrentCharFormat(format); }

@Cleiton-Bueno Thank you very much for providing me more information on the Yocto language selection.

Thank you! I see you specified height and width manually. That works so far. I will use that.

@romsharkov said in Incorrect Font Metrics: @raven-worx Didn't know about those methods, just tested it, for the lower case letter "g": QFontMetricsF::leftBearing() returns: -4.17188 QFontMetricsF::rightBearing() returns: 0.6875 But even if I add the (negated) leftBearing to the total text width it still doesn't cover the tail entirely, so what's wrong here? are you sure?! Those values seem to be correct / make sense according to your posted screens. Make sure that you add the absolute value (qAbs() for example). Also keep in mind that those values are only correct for the given font-size and that you can't add negative values to a image width. I guess you are just doing incorrect calculations. Can you show the code of the calculation?

Alright, problem solved. As so many times, the bug was sitting between chair and keyboard. In the FontLoader, I had the name property set. Which is set automatically if a font is loaded by source. https://doc.qt.io/qt-5/qml-qtquick-fontloader.html Having the name property set while loading a font by source is no problem under macOS but under Android, one Devanagari font started to dominate all instances, where Devanagari symbols appeared and all logic, how fonts are applied falls apart.

@raven-worx Thanks bro, very helpfull.

Please report a bug at bugreports.qt.io.

@mrjj Yes, What I did was QFontDatabase::addApplicationFont("/usr/share/fonts/truetype/Open_Sans/OpenSans-Regular.ttf"); and then select "Open Sans" on the QtDesigner

@mrjj I check and tried to replicate what the sample does but still doesn't work. I do notice the sample code uses the font in QTextDocument. Not sure if it matters. Also, from the documentation, weight and italic shouldn't matter once you set the style name http://doc.qt.io/qt-5/qfont.html#setStyleName However, I got it to work by using QFontDatabase::font() which takes the style name.

I've created a task https://bugreports.qt.io/browse/QTBUG-50984 so it doesn't get forgotten.

I found that this application also has the same issue (same error message when doing the same thing): https://local.ugene.unipro.ru/tracker/browse/UGENE-5411

Hi, AFAIK, you can't when calling the static methods, it's also a native file dialog so it should follow your OS settings

Hi and welcome to devnet, Are you using a special font ?

This is correct. This will be most likely a Windows-related problem with the ttf font.

I found a workaround: Define environment variable within Qt application startup context: QML_USE_GLYPHCACHE_WORKAROUND = 1 Look on this topic: https://forum.qt.io/topic/39803/font-rendering-bug-on-some-android-devices/7

@mcosta Hi, I'll certainly take a look at it. So I guess it's not only changing the font xD Thank you.

thank you very much....

ty, I have downgraded some packages (libglapi-mesa f.e.) and reinstalled some others. nopw everything is fine!

Hi and welcome to devnet, What version of Qt 4.8 are you currently using ?

BarSeries { id: currentPlot axisX: BarCategoryAxis { id: categoryAxis labelsFont:Qt.font({pointSize: 6}) Qt.font function accept an javascript object with all keys relevant to font. The most commonly used properties are: string font.family bool font.bold bool font.italic bool font.underline real font.pointSize int font.pixelSize
