I have a popup whose coordinates depend on the coordinates of the object on the canvas, and when I zoom need to recalculate the coordinates for the popup, depending on the zoom factor.

Take a look at canvas.viewportTransform property.
It contains all viewport transformation stored as array [a, b, c, d, tx, ty], where:
a -– x scale
b – y skew
c – x scew
d – y scale
tx – x translation
ty – y translation

I tried this, but tx and ty more than the actual offset. Need some kind of coefficient for them
