Slight change to hillshading is not sufficient IMHO. The screenshots here are of OAM v4 GreatBritainML using Locus internal theme at zooms 16-12. The road is quite visible at high zooms but disappears into the shadows as the zoom gets less.

PS This forum software is trying very hard to prevent me from posting but I will not be beaten.

PPS you may need to download the screenshot on a PC to view it properly.

Increase Map Resolution for vector maps unchanged in the new beta, I think. Reducing zoom level and then magnifying really doesn't work. Texts are enlarged, yes, but other details disappear, depending on the zoom level at which they appear. And roads are no more visible.

Regarding label layers and so on, Emux's Cruiser GL on android is a great example of what can be done with a separate text layer. Two finger rotate and perspective view keeps the texts horizontal. It even has an optional 3d building view. The rest of the app isn't a patch on Locus however but as an example of map rendering and routing it's excellent.
It uses Mapsforge maps and themes but (I think) a different rendering engine.

so hiding and showing points back solved this problem and now it's fast as before? Good to hear. It may be then small slowdown caused by automatic map loading I found yesterday. So hope it won't repeat with next Beta version.

It's working fine now, thanks.

Zoom lock on Pro: First tap on button restores the last zoom lock magnification immediately. Second tap reverts to initial unmagnified view.
Zoom lock on beta: No immediate effect on first tap. (That's ok but not so convenient) Second tap keeps the same magnified view until I adjust the zoom when it reverts gracefully to a standard magnification and zoom to display the same area. Personally, I don't find that intuitive or nearly as useful as the current Pro method which gives one tap to magnify an area of interest or confusion, second tap to revert.

I don't know if I understand correctly? The PRO version selects the map theme. The preferences would make no sense if the map theme could not be selected. What would be the prefix "tourism" with a car theme map?

Now that Locus is supporting two parallel sets of themes - for LoMaps/MF3 and for MF4 - selecting a theme is not sufficient as the theme has to be the right type for the current map. Really the map type has to be selected as well. But that presupposes that type of map is available on your device.

@john_percy
what you mean by "adding 54 POIs to Locus"? Just ordinary points from own database? If not, how to simulate this slowdown caused by points? 54 points should really have absolutely no impact on performance, weird.

I manually entered the co-ordinates, moved to the location, added point, edited name and icon 54 times. 54 points normally don't slow down Locus (much) but maybe the adding and editing process did. I don't know. Anyway something did and restarting the phone didn't help, only turning the points off and then on again!

Why do you think that scale x2 is not correct? Simply check scale line on the bottom of the map to confirm that distance factor really scale x2.

You are absolutely right, sorry. For some reason I was convinced that two zoom operations were needed to scale the map by 2. Maybe connected with the way vector road widths scale by 1.5x (or whatever) on each zoom operation.

(Also to John's post): it is correct that the visible area remains the same. Usage of this feature is to see bigger content in the same area. So rescale maps by 200% result in using lower zoom level scale to 200% (to keep same visible area).

Anyway as I see, John is correct that result is ok for raster maps, but not exact for vector maps. Most probably because the road in lower zoom level X is thinner than in next zoom level Y, so "road width X times 200%" is not same as expected "road width Y times 200%". Hmm, an alternative solution should be using still the same zoom level rescaled by X% and display a smaller area

(a) As I see it, with raster maps "increase resolution" actually mimics a lower resolution device showing the same map area. It may have some use, but what I would have expected is a magnifying effect a bit like Zoom Lock provides. So I prefer your alternative solution. (As it stands, for some of my custom raster maps at some zoom levels it has no effect at all, depending on what real zoom levels the online map provides.)
(b) For vector maps also I would prefer your alternative solution. Some days in the field it is difficult to see the detail on the map and I just want to be able to magnify the display. The current arrangement is little help to me for this. I know Zoom Lock will do this but it does just that and locks the zoom. I want the flexibility to be able to turn on Increase Resolution (screen magnification really) by a click in my Quick Settings menu and still be able to zoom in and out of the map at will.

It seems to me that the hill shading gets increasingly intense at lower zoom levels to the point where it can easily obscure important map details in hilly terrain.
I have two requests
1. Please turn down the volume control at lower zoom levels so the hill shading is more visually consistent
2. Please introduce an intensity control for hill shading in settings

Two fingers on map; drag down.
Two fingers on map; drag up to restore to flat map view.
Menon has said it's not yet working properly.

@slarti76 But wouldn't you expect road widths to increase in the same way as texts do?

I'd just noticed the same issue with "increase map resolution" on a vector map. If I lock the zoom then magnify the map, everything grows in size, which is correct and expected. If I "increase map resolution" to 200% the texts grow by 200% (linearly) but the map otherwise goes to an enlarged  version of the next lower zoom level, displaying exactly the same map area. The road widths are only slightly greater.
What's more, I'm fairly certain that the change from one zoom level to the next is not 200% (2×) but ✓2×. Two steps of zoom are needed to change a linear distance by a factor of two. If I'm right, I suspect the percentage zoom displayed in the top bar when I do a two finger zoom is incorrect.

Is there a definitive guide to the usage of these tags anywhere?

Sent from my moto g(6) plus using Tapatalk

As a result of the changed way the new beta deals with scaling maps for devices of different resolution, I've put together new versions of my Mapsforge version 4 compatible themes. They are effectively add-ons to the Voluntary themes. At present they are solely for the beta version and will simply not appear in the list of available themes in the current release, hence I have named them Voluntary Mapsforge beta and Velocity beta.
Download, unzip and add to your Locus themes directory.
Please let me know if they work for you.

@menion Good!

Also. I spent some time today adding 54 POIs to Locus and the map redrawing got slower and slower and sometimes whole tiles were missed out until I moved the map back and forwards. Restarting the phone didn't improve matters but hiding all the points then displaying them again speeded things up to normal speed and full display. Is this possible?

Hmm to be true, I see no simple solution here... Anyway, in these cases, when the text that appears in the second tile should be drawn over already visible map tile, it is a problem. For now ...

I thought Mapsforge had a solution to this, involving a separate text layer and iterating around the active tile for the truncated text. I guess it's not the fastest process.
