NOTES:

Plugin position is calculated with the salign, offsetX and offsetY parameters. The salign parameter works as described in the FPP documentation, and the offsetX and offsetY values are added to get the final position.

If all the different components are used their relative Z-levels would be:

The enabled parameter:
If set to enabled=0 initially, you can avoid showing the logoMeter when a preview pano is loaded. Then you can enable it dynamically ("external.logometer.enabled=1") before the main pano starts loading.

The uncover parameter:
If not used, the progress meter works as usual - growing from left to right.
If the parameter is set to uncover="1", the progress meter is drawn in full length from the beginning and used as a mask to cover the background. When loading starts, the mask will gradually shrink to the right, revealing the background.

The reload parameter:
If set to reload=1, the meter will also show when a pano is reloaded. The default is reload=0, which means that the meter will only be shown the first time a pano is loaded. The reason for this is that if the pano is reloaded, it has already been cached, so the meter would probably just flash on and off very quickly.

The tweenL and tweenU parameters:
The images used can also be Flash .swf files. If they contain tweens that you want to synchronize with the pano loading, they have to meet the following requirements:

1. The tweens must run between frames 1 - 100.
2. Frame 1 must contain an ActionScript stop(); command to prevent the tweens from playing automatically.

In the textLoaded parameter you can use the following placeholders:

%L	kilobytes downloaded
%T	kilobytes total
%P	percentage downloaded

The postCommand parameter:
With this parameter you can send commands to FPP when loading of the pano is complete. There is of course an event in FPP that you can use. But if you are using the delay parameter, which is used to keep the meter (logo) visible for a while after loading, you can also delay the execution of these commands.

As you can't use the &;=| characters here in the XML file, you have to encode them as follows:

Example FPP xml file:

<logoMeter>
   salign=MC
   enabled=0;
   size=207x125
   alpha=1
   delay=0
   postCommand=global.showTexts()

   radius=15
   bgColor=0xFDE018
   borderColor=0x000000

   imageL=img/logoeniro.png
   imageLPos=9:9

   imageU=img/enirobar2.png
   imageUPos=9:79

   meterPos=9:80
   meterSize=187x15
   meterColor=0x0000ff

   textPos=9:100
   textColor=0x303030
   textLoaded=We have loaded %L kilobytes
   textLoadFailure=loading failed
   textParsing=parsing
   font=Verdana
   fontsize=11
</logoMeter>
