Bug in ImageInfo ?

String list= ImageNameList("",";")
String imagePlot = StringFromList(0,list, ";")
info=ImageInfo("",imagePlot,0)

print ImageInfo("",imagePlot,0))


There is a space between "plane=" and the variable.

That makes it impossible to adress the plane with:
 variable plane=str2num(StringByKey("plane",ImageInfo("",imagePlot,0)))



[Fixed with]
 info = replacestring(" ", info, "")
Curious note here since StringByKey has a default ":" as the keystr. Is the mistake that you have forgotten to set it as "="? Alternatively, does this work?

variable plane=str2num(StringByKey("plane",ImageInfo("",imagePlot,0),"= "))

#include <WMImageInfo>

// The WMImageInfo procedure file contains functions for retrieving information about image plots.
// Included are WM_GetColorTableMinMax, WM_ColorTableForImage, WM_ColorTableReversed,
// WM_ImageColorTabInfo, WM_ImageColorLookupWave, and WM_ImageColorIndexWave.
Function GetPlane(graphName, imageName)
    String graphName, imageName
   
    String infoStr= ImageInfo(graphName, imageName,0)
    Variable plane=str2num(WMGetRECREATIONInfoByKey("plane",infoStr))
    return plane
End
