svg - How to calculate the y coordinate of a rectangle without transforms in Inkscape? -

-

imagine have inkscape file following rectangle:

screenshot

i want calculate y coordinate reported inkscape (596.654).

how can (manually) ?

i tried this:

  1. the top of page seems have y coordinate of 744.
  2. i subtract number y coordinate of rectangle in xml editor (417) , height (37) , 744 - 417 - 37 = 290.

note rectangle doesn't have transforms , doesn't belong group.

here's simplified version of svg relevant information included:

<svg width="297mm" height="210mm"      viewbox="0 0 1052.3622 744.09448">   <g transform="translate(0,-308.26772)">     <rect x="216.1537" y="417.34927"           width="385.25827" height="37.859257"           style="stroke-width:1;"    />   </g> </svg>

despite thought, there is transform in there (in group).

svg internal coordinates have origin in top left. whereas inkscape displays converted value relative more normal origin @ bottom left. displayed value takes account stroke width.

your rectangle drawn (internal coords) at

y = recty + translatey   = 417.34927 - 308.26772   = 109.08155

the page has height of 744.09448. displayed ccoordinate be:

y = pageheight - recty - recth - strokewidth/2   = 744.09448 - 109.08155 - 37.859257 - 0.5   = 596.653673
