Hello,
How do measurement actions work?
I added TImageEnViewMouseMeasureLength action to my ActionManager, and set TImageEnView.RulerPararams.Units to ieuMillimaters.
However, measurements are still in pixels. Am I missing something?
Regards, Ronald |

Hi Ronald
What is displaying measurements? A layer, a measurement tool, the ruler?

Hi Nigel,
I think the Action sets TImageEnView.MouseInteractGeneral to miMeasureLength. I guess a LineLayer is created? Both guesses are based on source code studying, as I could not find this in the helpfile.
Help topic TIEMouseInteract says SetScale has to be called, which I did, but I could not find how to speify unit, I expected TImageEnView.RulerParams to be valid for all measurements..
The MeasureIt sets units at global level, which I am a bit reluctant to do, as I have several images with different units.
Regards, Ronald |

Sorry Ronald, I missed that you mentioned TImageEnViewMouseMeasureLength. Are you using 9.0.0? I think that was an issue resolved in that release.

Hi Nigel,
Thank for explaining. So, there is no possibility to have 2 TImageEnViews visible, 1 measuring in millimeters and 1 measuring in pixels?
In the helpfile, I noticed that I can also specify measureunits by setting LayerDefaults. However, I did not get that to work.
What I do:
I set LeayerDefaults.Add(IELP_RulerUnits + '=' + Ord(ieuMillimeters).ToString); but measuring via action is still in pixels, not in millimeters. AM I missing something?
Regards, Ronald
