I want to measure length between two point when image zoom is 800, when I set MouseInteractVt = miDragLen, I got the first length value; when I set MouseInteractVt = miPutRuler, I got the second length value. The first value does not equals the second value.Even more strangely, when MouseInteractVt = miPutRuler, I release the mouse the value will auto change. Why? Moreover, when MouseInteractVt = miDragLen, how can I keep the measurement result on image. Thank you! |

Unfortunately I cannot replicate. Could you send a screenshot or a project with image which replicate this problem? |

I think this is not real reason because when MouseInteractVt = miDragLen, the measure value will not change when releasing the mouse at large zoom(greater than 100). |

Ruler object can have a different measure unit than DragLen (that is not an object, but just a measuring tool). Have you set ObjRulerUnit equals to TImageEnVect.MUnit?
ImageEnVect1.ObjRulerUnit[-1] := ieuINCHES;
ImageEnVect1.MUnit := ieuINCHES;
Also, at large zooms little differences can be normal due the math rounding.
