Distance Gauge - Flip Vertical or rotate 180* - Request Help

Good evening VIRB Edit users. I need your help in understanding how the gauge editor works in VIRB Edit 4.1.1. I am trying to flip the vertical alignment of a distance gauge, but since it is a multipurpose gauge, other measurements could be made. After searching threads, I haven't seen anything that would equate what I'm attempting to do.

What I've done:
1. I am using VE 4.1.1 software on Win7.
2. I flipped the radial marks and gauge "face" arc 180* using GIMP.
3. I played with the red radial ring using the Advanced Settings in the Gauge Editor.
4. After playing with all the variables of the radial ring, it doesn't match up (in reverse) to the original.

The Advanced Settings are a bit out of my depth of understanding. Would anyone care to explain it further?

Attached is a zip file that contains my work thus far. I appreciate any and all help in advance!

Cheers,

Russell,

Thank you very much for the help! How did you fix the gauge? When it comes to editing gauges I am a noob! I'd like to understand more about the pivotX and pivotY points.

Not to fault my persistence, but I also made a similar inverted distance gauge late last night (more like early this AM). I modified an acceleration gauge to measure RPMs. When I looked at the advanced settings of that (RPM) file, I could see how the ribbon rotated. So I broke out the GIMP to edit that RPM gauge for a bottom orientation. Afterwards, I resized the tick marks image to 500x500px for better fitment. I also used the similar minAngle and maxAngle values to achieve the ribbon movement. My only glitch is that the distance value slightly varies (off by 0.01mi) from another distance gauge (only displays values).

I did not see that discrepancy with the gauge that you fixed, Russell.

I've attached a ZIP file that has both inverted distance gauge (not Russell's gauge) and vertical RPM gauge directories in case anyone is interested. They are:
GeoS72-Distance Inverted
GeoS72-RPM Vertical

Again, thank you for the help, Russell!

Cheers,
George

The pivot point and min and max angles were the issues. The pivot point should be the center of the image. The image is 500x500, so if the image were in the center of the canvas, the pivot point would be [250,250]. Because the image was shifted up this made the pivot point [-2,-365]. After that, it was determining the angles for clipping. We're clipping everything but the bottom of the circle, so it had to start around 270 and end around 90. It was mostly trial and error from there.

Russell,

Thanks for explaining! That puts things into perspective for me.
