That's why I was expecting that when I use the 'magnifying glass' there won't be any new features showing up at the same extent, i.e. smaller streets or more labels. But there are, same as if I've changed the scale. </div><div dir="auto"><br></div><div dir="auto">Kind regards, </div><div dir="auto">Idan </div><div dir="auto"><div class="gmail_extra" dir="auto"><br><div class="gmail_quote">On 1 Mar 2018 19:00, "Denis Rouzaud" <<a href="mailto:denis.rouzaud@gmail.com">denis.rouzaud@gmail.com</a>> wrote:<br type="attribution"><blockquote class="quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr">Hi Idan,<div><br></div><div>I'll reply for the part I'm aware of.<br><br><div class="gmail_quote"><div class="quoted-text"><div dir="ltr">Le jeu. 1 mars 2018 à 06:05, Idan Miara <<a href="mailto:idan@miara.com" target="_blank">idan@miara.com</a>> a écrit :<br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr">Hi,<div><br></div><div>I was examining the Scale/Magnifier widget in QGIS3.</div><div><br></div><div>I couldn't find any difference in the output picture between the following combinations (example):</div><div>Scale 1:1,000 and magnifier 1000%</div><div>

<br></div><div>Is this by design ?</div></div></blockquote><div><br></div></div><div>Yes this expected. The idea of the magnifier is for having a "magnifier glass" to do scale-dependent editing. In my scenario, that was useful for fine-placement of labels.</div><div>But if you don't have scale-dependent rendering (mainly labels I guess) or using map units instead of points for symology, it won't (shouldn't) change anything.</div><div class="quoted-text"><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr"><div><br></div><div>I was expecting a different results, for instance, if I load OSM, and I change the magnifier while the scale is fixed I was expecting to see the same rendered image, just smaller/larger (i.e. same map features, no new labels/roads etc.)</div></div></blockquote><div><br></div></div><div>well, if you magnify with a fixed scale that will change the extent, you can't see as much features in the map.</div><div class="quoted-text"><div> </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr"><div><br></div><div>Also, is there an option to set the resolution in Map Units per pixel, i.e.:</div><div>Meters Per Pixels (when the units are meters, as in UTM) or </div><div>Degrees/Seconds per pixel (when the units are Degrees, as in Geographic) ?</div><div><br></div><div>I guess it makes more sense for most people to use Scale, but when I want to examine specific pixels of a raster usually it's easier for me to think in Meters Per Pixels in respect to the Map Units, for instance, when I know that my map is in 10 Meters per pixel, then if I set the Map canvas resolution to the same value of 10 Meters per pixel I expect to see the pixels in 1:1 as one pixel on the raster is one pixel on the map canvas.</div><div><br></div><div>Regards,</div><div>Idan.</div></div><br></blockquote><div><br></div></div><div>Best wishes,</div><div>Denis </div></div></div></div>
