Extension summary

Rooler is a utility for automatically measuring on-screen graphics.

Not quite like every other measurement utility out there (though there are quite a few)- this one analyzes the graphics and automatically finds the edges. It's essentially an automatic ruler, for the web.

  • Measures the bounds of graphics
  • Measures the distance between graphics
  • Allows ensuring correct positioning of elements, even in deeply nested element hierarchies.

It's quick and easy. Give it a shot.

You can also try Rooler in your browser at http://peteblois.github.io/rooler.js.

Лучший инструмент среди аналогов.

色の差を判別して距離を測ってるようです。 手軽に素早く距離を測れてレイアウト確認がとても捗ります! 今まで苦労して小さい部分の距離を測るのに苦労していましたが、これなら一瞬です! ただ注意したいのが、色を判別して測っているので、 要素自体を判別しているわけではありません。 例えばあるボックスまでの距離を測りたい時に、 そのボックスに背景と同じ色のボーダーがあった場合、 そのボーダー分の距離は含まれません。 これはこれで便利ですが、このことは頭に入れておく必要があります。

Toller Ansatz, Abstände zu messen! Hier werden nicht die Abstände anhand von Elementen gemessen, sondern anhand von Farben. So kann man auch leicht die Zwischenabstände von Buchstaben und Co. herausfinden
