And also the pixels delta positions vs the grid lines are changing
depending if your objects are on the left or right -or- top or
bottom of your patch.<br>

Hello Jonathan,<br>
<div class="moz-signature">It's a great feature! Thanks a lot. <span
class="moz-smiley-s3"><span>;-)</span></span><br>
<br>
On my side the experience with Purr Data 2.15.2 (Albert's
20201030) under Ubuntu 20.04 / Linux Mint 20.0 is not positive
and the behavior changes with the zoom level.<br>
I'm taking the top/left of the objects being the reference point
with a screen resolution of 1920 x 1080 and Purr Data Grid = 10.<br>
<br>
With Zoom level = 9.<br>
I take any object and move them with the mouse. Snap to Vertical
grid is OK but not the horizontal one which -2 pixels down the
grid.<br>
<br>
Change Zoom level = 13.<br>
The reference point of above objects has moved by -2 pixels to
the left and no change on the horizontal one.<br>
Moving them with the mouse, now Snap to Vertical grid is
effectively -2 pixels left and the horizontal one is still -2
pixels down. So no possible alignment to the grid.<br>
<br>
Change Zoom level = 15.<br>
Same as for ZL 13 with more shift: from -2 pixels to -5/6
pixels, but never on the grid.<br>
<br>
Best, Joseph<br>

<div>Thanks a bunch, I've really been waiting for this! :)</div>
<div><br>
</div>
<div>I already merged this into my testing branch and had a
quick look, works fine for me so far.</div>
<div><br>
</div>
<div>I noticed one cosmetic issue, though. I'd suggest
changing the translations for <span class="gmail-line"
id="gmail-LC420" lang="html"><span class="gmail-s">prefs.gui.grid.show_grid
and </span></span><span class="gmail-line"
id="gmail-LC417" lang="html"><span class="gmail-s">prefs.gui.grid.show_grid_tt.
This option is still</span></span> displayed as "grid
background in edit mode" right now, but has actually
become a "snap to grid" option.</div>
<div><br>
</div>
<div>My suggested translations can be found at <a

(@Joseph, can you please check my French? Thanks.)</div>
<div><br>
</div>
<div> I already have these in my testing branch, so I can
add this to your MR if you want. Just let me know.</div>
<div><br>
</div>
<div>If anyone else wants to give it a go, try
purr-data_2.15.2+git4745+7aca2748 which is currently
building in the OBS preview channel at <a

start moving the selection, it kind of "snaps<br>

to fix it so<br>
it always snaps to the closest gridline for the general
case (e.g., in<br>
the assignment to dx/dy below the snap_got_anchor
conditional)?<br>

<div>I haven't thought about this in any depth, but have you
tried rounding just xnew-xwas to the nearest grid point
and finally adding snap_dx, likewise for y? That said,<span
class="gmail-line" id="gmail-LC5821" lang="c"><span
