Missing Font led.ttf

by **dhudach** » Tue Apr 23, 2019 12:07 pm

I'm working with fgpanel making great progress. But one of the instruments must need a Font:

Missing font : /path/to/flightgear/../fgdata/Fonts/led.ttf

Font directory doesn't contain that file. I was hoping to figure out where it's getting set but I could not. These returned no results (I'm sitting in the correct directory):

find . -name "*.xml" -exec grep -il 'led.ttf' {} \;
find . -name "*.cxx" -exec grep -il 'led.ttf' {} \;
find . -name "*.hxx" -exec grep -il 'led.ttf' {} \;
find . -name "*.ac" -exec grep -il 'led.ttf' {} \;

If a different led file can be used, which one and in which file I would find it (how to find it) or if led.ttf can be found someplace.

Silly me, if I know which one of these is suitable, I can just copy it to led.ttf (LED-8.ttf or LED-16.ttf)

Thanks,
Dave

Strange, I don't find led.ttf in any of the FlightGear repositories. Where does this message come from? Are there other messages? I do see led.txf which is explained in Docs/README.osgtext. The led.txf file is used quite a lot in FGAddon. Did you copy and paste the error message?

The error came from fgpanel. I'm building a sim cockpit and am going to use fgpanel. I probably wouldn't mind, but the message simply repeats and scrolls. I don't know where it comes from. It's odd. So I just copied LED-8.ttf to led.ttf in the Font directory and of course the message goes away. I don't know which if any of the instruments it will impact, but I'll probably find out. Here is basically what continues to scroll by in the command terminal when I run fgpanel:

OpenGL version = 3.0 Mesa 17.2.8

I'm guessing you have led in your panel configuration files.
fgpanel is expecting a .ttf file so "led" becomes "led.ttf".

FGTextLayer could use an update to only append ".ttf" when a font extension was not specified.

Ok, I'll give it a look. Thanks.

Ok, I indeed found led in the following Instrument files:

./install/flightgear/fgdata/Aircraft/Instruments/dme.xml
./install/flightgear/fgdata/Aircraft/Instruments/radar.xml
./install/flightgear/fgdata/Aircraft/Instruments/fps.xml
./install/flightgear/fgdata/Aircraft/Instruments/adf-radio.xml
./install/flightgear/fgdata/Aircraft/Instruments/navcom-kx155.xml
./install/flightgear/fgdata/Aircraft/Instruments/KAP140TwoAxisAlt.xml
./install/flightgear/fgdata/Aircraft/Instruments/clock.xml
./install/flightgear/fgdata/Aircraft/Instruments/kr-87adf.xml
./install/flightgear/fgdata/Aircraft/Instruments/navcom-radio.xml
./install/flightgear/fgdata/Aircraft/Instruments/oat.xml
./install/flightgear/fgdata/Aircraft/Instruments/wxradar.xml
./install/flightgear/fgdata/Aircraft/Instruments/rpm-c172s-digi-hobbs.xml
./install/flightgear/fgdata/Aircraft/Instruments/KAP140TwoAxis.xml
./install/flightgear/fgdata/Aircraft/Instruments/autopilot.xml

And FGTextLayer.cxx has the following method:

Code: Select all: void FGTextLayer::setFontName (const string &name) { if (The_Font_Path.isNull ()) { char *Env_Path = ::getenv ("FG_FONTS"); if (Env_Path != NULL) { The_Font_Path = SGPath::fromEnv (Env_Path); } else { The_Font_Path = ApplicationProperties::GetRootPath ("Fonts"); } } m_font_name = The_Font_Path.local8BitStr () + "/" + name + ".ttf"; }

Which is called by flightgear/utils/fgpanel/panel_io.cxx. And in my case, I'm displaying dme on the panel which of course uses dme.xml in the above list.

And that is all very helpful, however, other than my hack to copy led-8.ttf to led.ttf to eliminate the error, I really don't know what led.ttf should be.

Thanks,
Dave

Does the font work if you modify Aircraft/Instruments/dme.xml from:

Code: Select all: led

to:

Code: Select all: led.txf

Thanks,

Interesting, the error actually occurs because of Aircraft/Instruments/clock.xml. I removed the copy of led.ttf file that I created in Fonts and re-ran with dme.xml in fgpanel and oddly there were no errors. I found that strange because

Code: Select all: led

is used numerous times in dme.xml. So I removed dme.xml from my fgpanel definition and added clock.xml and bingo, I got the led.ttf file not found. Ok I then changed the above font in clock.xml to:

Code: Select all: led.ttf

and I got what I suspected I would get:

7.72 [ALRT]:cockpit Missing font : /home/MYNAME/flightgear/install/install/flightgear/bin/../fgdata/Fonts/led.txf.ttf 6.5

and it's because setFontName in FGTextLayer.cxx appends "ttf" to the name in all cases:

Code: Select all: void FGTextLayer::setFontName (const string &name) { if (The_Font_Path.isNull ()) { char *Env_Path = ::getenv ("FG_FONTS"); if (Env_Path != NULL) { The_Font_Path = SGPath::fromEnv (Env_Path); } else { The_Font_Path = ApplicationProperties::GetRootPath ("Fonts"); } } m_font_name = The_Font_Path.local8BitStr () + "/" + name + ".ttf"; }

I have a laundry list of tasks I need to get done on my fgpanel implementation so this doesn't actually rise to the highest priority for me. But it may impact others and it's one of those little details that may need some attention. Also, having that error message scroll by constantly is probably not the best practice. So my hacked solution of copying led-8.ttf or led-16.ttf to led.ttf for the moment solves the repeating error messages.

On a side note, and I don't know how the code works, but I do find it odd that as fgpanel is running it constantly needs to run IO to find the font rather than obtaining all properties for a given instrument one time, say during initialization. But that's just a side note. It's not something I've totally investigated, just a cursory assumption based on observation.

Thanks,
Dave

But what about led.txf? Note this is not a true type font (TTF)!

by **dhudach** » Wed Apr 24, 2019 2:08 pm

I'm not sure what you are asking here:

But what about led.txf? Note this is not a true type font (TTF)!

Perhaps you are asking that in addition to led.ttf missing, why is led.txf sitting in the Font directory. Note that Folder contains numerous txf as well as ttf files.

See this discussion from 2016 on the mailing list: https://sourceforge.net/p/flightgear/ma ... sg35559952
I cannot test FGPanel right now, but looks like it no longer loads .txf files and the instruments have not been updated since (or the font converted to .ttf, as that'd probably be the better solution).

by **dhudach** » Wed Apr 24, 2019 2:25 pm

Ok, so if I'm understanding everything then, it appears my temporary solution of copying one of the other led ttf files to led.ttf is ok for now.

There was a change back in 2016 which probably broke this:

The code can no longer translate led as meaning led.txf. My suggestion is to see if led.txf can still be used. If so, then the fix is easy. You can change all FGData instances with a command such as:

Code: Select all: find Aircraft/Instruments/ -name "*.xml" -exec sed -i "s/font>led<\/font/font>led.txf<\/font/g" {} \;

This results in a diff like:

That was one of the original tests. I changed led to led.txf in clock.xml and it results in this error:

7.72 [ALRT]:cockpit Missing font : /home/MYNAME/flightgear/install/install/flightgear/bin/../fgdata/Fonts/led.txf.ttf 6.5

and it's because setFontName in FGTextLayer.cxx appends "ttf" to the name in all cases:

Code: Select all: void FGTextLayer::setFontName (const string &name) { if (The_Font_Path.isNull ()) { char *Env_Path = ::getenv ("FG_FONTS"); if (Env_Path != NULL) { The_Font_Path = SGPath::fromEnv (Env_Path); } else { The_Font_Path = ApplicationProperties::GetRootPath ("Fonts"); } } m_font_name = The_Font_Path.local8BitStr () + "/" + name + ".ttf"; }

So for now, since I have a solution that eliminates the error and seems to get the clock display showing the time, I can move on. Hopefully if there is a real fix it will be posted here and I'll be able to make use of it.

Thanks,
Dave

But beyond the missing font, it may be instructive to know that fgpanel panel_io.cxx is making repeated calls to retrieve the font during runtime. If it's happening for clock.xml, I'm guessing it's happening to other instruments. And so it makes me wonder if fgpanel should initialize properties one time. But again, I am just making an observation here ...
