Zoom factor impacts raster layers

[VICTORIGIS]

Hey, I've found the reason why my raster layer background is not shown in the kmz file. Whenever i use a zoom factor (for example 10), the raster layer appears in the top left corner as a small tile. The rest of the tiles just has a white background, with the vector layer in front.

But if i use a zoom factor of 1, the raster is shown perfectly fine with all vector layer on top. This is okay for my current work, but now the resolution is not the best. I´ll play around a bit more, but maybe someone has the same problem. Just use the zoom factor 1 and then maybe load more kmz files on your garmin device...

@VICTORIGIS Thanks for your observations. I have experienced issues loading KMZs generated with zoom > 1 in QGIS, but so far, my suspicion is that QGIS handling of multi-tile kmz files is the cause.

The reason I think this way is because if I load the same KMZ in a Garmin device, it shows up properly on that device.

Could you test the same KMZ that shows up as a small tile in a Garmin device and let me know if the same issues occurs?

Thanks

This could be the same issue as #22, for which I just left a comment that it should be reopened. I also suggested a solution (removing the statement

            mapSettings.setOutputDpi(target_dpi)

in line 384 of file GarminCustomMap.py (version 3.4.1), which I had suggested before but somehow got lost in the commit.

FYI: I just uploaded a new version with the fix by @chrismuller

Hmm, sorry folks, seems as though removing this line actually breaks execution on linux. The new version of the plugin, with this fix, doesn't work on my machine with QGIS 3.28.3 (and previously on 3.28.0) with a zoom factor that is not 1.0 (it works with zoom factor = 1.0).

Can anyone confirm that the plugin works WITHOUT this line (using a zoom factor not equal to 1.0)?
