[mtext.lpi] compiles under Windows, but shows no text. Are You able to look into this ?

I am unable to resolve this problem, as the project shows text correctly for me. I am using Windows 11 Pro version 23H2 on a laptop with Intel integrated graphics. Unless I can replicate the problem, it is hard to fix. I made a clean install using the latest stable version of Lazarus and directly cloning this repository.

I have also published the compiled Windows executable as mtext_windowsX86_64.zip with the latest release. I can download this compiled executable and see text on my computer.

Hello Chris, I opened Your Executable on my computer, and it doesn't show any text. So this can't be a source code issue .. and also not a Laz 32-bit / 64-bit issue. PROBABLY A "HARDWARE PROBLEM" ? I use a GEEKOM Mini-PC with - Intel(R) Celeron(R) N5105 @ 2.00GHz 2.00 GHz - Intel(R) UHD Graphics Thanks, Peter.

When I comment out this line of code in procedure TGLText.TextOut():

//if metrics.M[asci].xadv = 0 then continue; //not in dataset .. I get this:

@PeterOnDrums Am I correct that you are in a country that uses the comma as a decimal separator (1,23) instead of a full stop (1.23)? If so, why don't you download the latest commit and see if it resolves your issue.

Ah .. yes, I'm from Germany, Europe. We do have the comma as decimal separator :-) I'll give it a try - thanks !

@neurolabusc Thanks !

I can confirm that it works now, here on Windows 11, compiled als Win32 EXE !

To keep the size of text under MS WINDOWS while using scaling (High DPI) in the project settings I wrote this additional function:

procedure TGLText.TextOutHighDPI(x,y,scale: single; PixelsPerInch: integer; s: string); overload; //for Windows High DPI begin TextOut( x * PixelsPerInch / 96, y * PixelsPerInch / 96, scale * PixelsPerInch / 96, 0, s); end;

for unit glmtext.pas

The caller has to set the function parameter PixelsPerInch to Screen.PixelsPerInch (from TScreen)

@PeterOnDrums The latest commit should automatically scale font size when the application loads.
