Well, since I (thought that I) needed it in one of my codes, here is the way - it's actually quite simple if you draw things on a piece of paper:As you can see, this will make positioning a bit tricky, as while X works fine, the center of rotation is also based on where Y (the top) is defined for the meter, and there is really no way to have the anchor be actually in the vertical "middle" of the text string.
Code:
[Rainmeter]Update=100AccurateText=1DynamicWindowSize=1[MeasureRotate]Measure=CalcFormula=(MeasureRotate % 360) + 10[MeterBack]Meter=ImageW=100H=100SolidColor=47,47,47,255[MeterOne]Meter=StringX=50Y=50StringAlign=CenterCenterFontSize=12FontColor=0,0,0,0SolidColor=255,150,150,128AntiAlias=1Text=Hello World[MeterTwo]Meter=StringX=(50+[MeterTwo:W]*0.5*0+[MeterTwo:H]*0.5*Cos(Rad([MeasureRotate]-90)))Y=(50+[MeterTwo:H]*0.5*1+[MeterTwo:H]*0.5*Sin(Rad([MeasureRotate]-90)))StringAlign=CenterCenterFontSize=12FontColor=255,255,255,255SolidColor=150,150,150,128AntiAlias=1Text=Hello WorldAngle=(Rad([MeasureRotate]))DynamicVariables=1Statistics: Posted by Yincognito — Today, 6:14 pm
