#3124: d.northarrow incosistent placement when rendering to file/screen
-----------------------------------+-------------------------
Reporter: kuszinger | Owner: grass-dev@…
Type: defect | Status: new
Priority: normal | Milestone: 7.2.0
Component: Display | Version: svn-trunk
Keywords: render, file, display | CPU: Unspecified
Platform: Unspecified |
-----------------------------------+-------------------------
By further tests d.northarrow is rendered using at= paramter and
* when it is a '''screen''' display: at= parameter is used as '''top-
left''' of the graphics box containing the north arrow
* when it is a '''file''' rendering: at= parameter seems to be the
'''center-center''' of the northarrow (which is better, I think as
northarrow is somehow a "central" nature graphics figure (barscale is
linear and legend is areal)
See jpg file attached to this ticket. File rendering is on the left,
screen rendering is on the right of the screenshot. All cartographic
elements are located at=20,20 by parameter (percent).
Another discovery is that placement on the off-screen (file) rendering is
very precise, corners/centers of gadgets fit very precisely at 20,20
percent, meanwhile on display they don't.
