Need help as far as implementing custom font ..

Former Member over 9 years ago

I am trying to implement a custom font design .. and need to know SPECIFICS as to what I need to add.

I have looked at the samples .. and cannot get it to work. I always get an error message .. "cannot find source id_font_c64" or something similar.

I have something like this in my source:

using Toybox.WatchUi as Ui;
var font;

font = Ui.loadResource(Rez.Fonts.id_font_c64);

and in the xml file:

<fonts>
<font id="id_font_c64" filename="fonts/commodore.fnt" filter="READY0123456789:." />
</fonts>

I have the xxxxxx.fnt file and xxxxxxx.png files in my fonts folder.

What am I missing ?

Are you using Bmfont? When you generate your font you get a .fnt file and one or more .png files.. The .fnt is a text file. Where are you putting these files, and how are you defining them in your resources?

It looks like "xxxxxx.fnt" should replace the font you have in your resources....

When I build ..

Device Version 0.1.0
Device id 1 name "A garmin device"
Shell Version 0.1.0
Could not find symbol id_font_c64.
Symbol Not Found Error

in getInitialView (C:\Users\Kevin.Win8\Desktop\Garmin Dev\My Projects\DigitalVivo\source\DigitalVivoApp.mc:20)
Failed invoking <symbol>

Closing shell and port

I have a folder fonts (path = "C:\Users\Kevin.Win8\Desktop\Garmin Dev\My Projects\DigitalVivo\resources\fonts" including the files from the sample .. I just copied them over as a test.

I have a resources.xml file (Path =C:\Users\Kevin.Win8\Desktop\Garmin Dev\My Projects\DigitalVivo\resources) containing ...

<resources>
<fonts>
<font id="id_font_c64" filename="fonts/commodore.fnt" filter="READY0123456789:." />
</fonts>
</resources>

In the source ..

using Toybox.WatchUi as Ui;
using Toybox.Graphics as Gfx;
using Toybox.System as Sys;
using Toybox.Lang as Lang;
using Toybox.Application as App;
using Toybox.Time as Time;
using Toybox.Time.Gregorian as Calendar;
using Toybox.ActivityMonitor as Act;

class DigitalVivoView extends Ui.WatchFace {

hidden var mBattery1; // Battery Graphics 1-8
hidden var mBattery2;
hidden var mBattery3;
hidden var mBattery4;
hidden var mBattery5;
hidden var mBattery6;
hidden var mBattery7;
hidden var mBattery8;

hidden var mSteps; // Steps Graphic

var font;

function initialize()
{
WatchFace.initialize();

mBattery1 = Ui.loadResource(Rez.Drawables.battery1); // Battery Graphics
mBattery2 = Ui.loadResource(Rez.Drawables.battery2);
mBattery3 = Ui.loadResource(Rez.Drawables.battery3);
mBattery4 = Ui.loadResource(Rez.Drawables.battery4);
mBattery5 = Ui.loadResource(Rez.Drawables.battery5);
mBattery6 = Ui.loadResource(Rez.Drawables.battery6);
mBattery7 = Ui.loadResource(Rez.Drawables.battery7);
mBattery8 = Ui.loadResource(Rez.Drawables.battery8);

mSteps = Ui.loadResource(Rez.Drawables.steps); // Steps Graphic

font = Ui.loadResource(Rez.Fonts.id_font_c64);

Let me know if you need more information. I obviously did not build my own font files .. though I will once I get it working. I just used the ones from the sample for now.

There used to be a problem with spaces in the path name. If this has not been addressed then your folders "Garmin Dev" & "My Projects" will be causing problems. I've been away for a while so not sure if this still relevant.

Ok thank you .. I will give that a try.

The other thing .. I do have a drawables.xml file in the drawables folder. It is as below .. and I have no issues with it.
I just have issues when I am trying to add a font.

<drawables>
<bitmap id="LauncherIcon" filename="launcher_icon.png" />
<bitmap id="battery1" filename="battery1.png" />
<bitmap id="battery2" filename="battery2.png" />
<bitmap id="battery3" filename="battery3.png" />
<bitmap id="battery4" filename="battery4.png" />
<bitmap id="battery5" filename="battery5.png" />
<bitmap id="battery6" filename="battery6.png" />
<bitmap id="battery7" filename="battery7.png" />
<bitmap id="battery8" filename="battery8.png" />
<bitmap id="steps" filename="steps.png" />
</drawables>

I was thinking it was an issue cause there are 2 xml files .. but I tried everything I could think of and no resolution.

I don't believe there are any rules you have to follow with regards the XML files other than well formed xml. I think the file names are just for clarity. For example you could probably put all your resources in a file called myres.xml like this

<resources>
    <drawables>
        <bitmap />
    </drawables>
    <settings>
        <setting />
    </settings>
    <properties>
        <property />
    </properties>
    <strings>
        <string />
    </strings>
</resources>
