Re: [Qgis-user] Shifting a Geotiff image
Good to hear that worked. Last time I tried georeferencer on webodm output it didn't work (issue with images that already had CRS info). Sounds like the problem may have been fixed. 1 to 2 m out does sound suspiciously like a GDA94 vs GDA2020 (current WGS84) issue, but probably just a coincidence.

Re: [Qgis-user] Shifting a Geotiff image
Hi Grant - You can do this with a simple Linear transform using the built-in Georeferencer. I made a small video showing how https://www.youtube.com/watch?v=8a4M32Rkwck [https://mailtrack.io/trace/link/ebfeb1e55e3f8462089ce55d97e05185ae0619ed?url=https%3A%2F%2Fwww.youtube.com%2Fwatch%3Fv%3D8a4M32Rkwck=8747767=8f549a955495bf81] Hope that helps. --- Ujaval Gandhi Spatial Thoughts www.spatialthoughts.com [https://mailtrack.io/trace/link/69c992a0409ae934c5c0e2276997a6ee22503015?url=http%3A%2F%2Fwww.spatialthoughts.com=8747767=16f533b4cb0820fe] [data:image/gif;base64,R0lGODlhAQABAIAAAP///wAAACwAAQABAAACAkQBADs=3D] On Sat, Aug 12, 2023 at 9:48 PM Martin Weis via QGIS-User wrote: > Dear Perth, > > On 11/08/2023 09:14, Grant Boxer via QGIS-User wrote: > > I have a GeoTIFF image created using Web ODM and is mis-aligned by 1 to 1.5 > > m and I would like to move the image to register with the surveyed ground > > control points.

Ok I'm embarrassed now, it's been a while since I used QGIS and my layer had a bunch of categories in it. I was trying to right-click and double-click on one of the categories... If I right-click or double-click on an ACTUAL layer then it works as normal. My bad, sorry for the noise :) Cheers, Adam. ___ QGIS-User mailing list QGIS-User@lists.osgeo.org List info: https://lists.osgeo.org/mailman/listinfo/qgis-user Unsubscribe: https://lists.osgeo.org/mailman/listinfo/qgis-user
[Qgis-user] How to make HTML map tip size larger in QGIS 3.32
Hi all, Since upgrading to QGIS 3.32 the map tips are now working for me. However the HTML formatting seems to have changed. I can adjust the HTML to mostly work around it, however the one thing I can't figure out how to do is to change the frame size so the popup itself appears larger on the screen. Previously I was putting a photo in the map tip with and it would open up in a map tip 1024 pixels wide, so I could clearly see the whole photo. Now, in QGIS 3.32, the map tip seems to be limited to a postage-stamp sized box with scroll bars, so the image is the same size as before, but now I have to scroll around and I can only see a tiny bit of the photo at any one time. I have tried using
[Qgis-user] How to quickly open Layer Properties in QGIS 3.32?
Hi all, In QGIS 3.28 and 3.30 I was able to right-click on a layer to open the layer properties. I just moved to a new PC with a fresh QGIS install of 3.32.1-Lima (didn't carry my old profile across) and now when I right-click on a layer it gives me a popup where I can do very little, only show/hide the layer and change the symbol colour. If I double-click on the layer it brings up the "Symbol Selector" window where I can further tweak the symbol but do nothing else. If I go to the Settings menu and choose Options, then select the "Canvas & Legend" page, there is an option "Double-click action in legend". If this is set to either "Open attribute table" or "Open layer styling dock" then double-clicking a layer does just that, however setting it to "Open layer properties" causes a double-click to open the Symbol Selector window instead of the layer properties. The only way I have found to get the Layer Properties to open is to choose that menu item from the Layer menu, which is quite slow for something I do all the time. Is there a way to get the old behaviour back, either with the original right-click menu or at least some way to configure QGIS to open the Layer Properties on double-click instead of the Symbol Selector?
