Hi,

 

My first time trying to make a tape shift.  Any idea why the compass remains a black box with only the white line in the center?

 

<Gauge Name="Compass" Version="1.0">

  <Image Name="Compassbackground.bmp"/>

 

  <!-- Size = 102 x 42, black BMP -->

 

  <Element>

    <Position X="1" Y="1"/>

    <Image Name="CompassStrip.bmp">

 

    <!-- Size = 520 x 40, white text on black BMP -->

 

      <Nonlinearity>

        <Item Value="0" X="440" Y="0"/>

        <Item Value="359" X="81" Y="0"/>

      </Nonlinearity>

    </Image>

    <MaskImage Name="CompassWindow.bmp"> 

 

    <!-- Size = 100 x 40, black BMP -->

 

     <Axis X="50" Y="0"/>

    </MaskImage>

    <Shift>

      <Value>(L:KK_Compass,number)</Value>

    </Shift>

  </Element>

 

  <Element>

    <Position X="50" Y="0"/>

    <Image Name="CompassLine.bmp">

 

    <!-- Size = 2 x 40, white BMP -->

 

    </Image>

  </Element>

</Gauge>

 

 

LUA displays 58 degrees onscreen (taken from offset x2B00 and rounded), this matches the existing compass reading.

 

I've tried painting the Mask file 1,1,1 as indicated here:

Same thing, no tape in gauge, just black with my white centerline.

P.S.: The size lines were added as comments to help here, they are not part of my source.

SOLVED!

 

24bit BMP using 1,1,1 as colour for the mask was the answer.
