Sorry, it should be --zoom 4. And it does look a lot nicer with --zoom 4 than scaled with gimp afterwards, because the cubes get a bit bigger.

Oh and 99% of the praise should go to the original writers of minetestmapper for the clear code. I just bolted on some brute force isometric overdrawing :-)

Hello, having tried all the geometries and always having the same result I come to ask for some help because this line always appears: "Exception: Image format not supported by gd" So what is this "gd"??

gd is the library minetestmapper uses to save images. You need to give a valid extension to the output filename.
For example -o out.png or -o out.jpg I think gd supports jpg, gif and png

A thousand thanks so I can have some "isometric maps". You have done an incredible job. Congratulations and thank you again.

Thanks for the praise :-). But as I said before, 99% of the work is done by sfan5, mireq, Shadowninja... So the largest part of the praise should go to them :-)

Of course I associate sfan5, mireq, Shadowninja to these thanks.

I'll look into it. What system do you try to compile on? My first guess would be an incompatible gcc version.

[edit] That was it. It should now compile with gcc v5 or higher (or lower, but I didn't test that).

I added a flag to tune the height shading in isometric mode.

Hello, Gaël I managed to compile from the folder extracted from the "zip" with the latest version of C++ on Ubuntu 18.04.1 LTS. Sorry for the screens but I can't insert the images in the forum, still a beginner despite my age.

Thank you, actually I had already solved my problem but forgotten to reply here :)

Hi,

i want to use this https://github.com/est31/leaftest to get an zoomable worldmap. This will need this minetestmapper. My question is, what git-repo is the best to do this? I found some forks an i am now a little bit confused what is the right version :)

I will use this on an Ubuntu 18.04 LTS Server, if that's important.

greets

My fork includes code to set up a leaflet map. This was my main reason to add the --tiled flag.

Use the iso branch from here:
https://github.com/wziard/minetestmapper/tree/iso

edit:<snip example script, I added it to the repository>

I put an example script to generate a leaflet map into the 'leafletmap' subdir.

p.s. it you want an *isometric* leaflet map you'll also need the mergeiso utility to merge the isometric diamond shaped tiles into square tiles as input for the buildpyramid utility.

wziard,

I downloaded your iso branch, mainly because I saw a script for generating colors.txt values. I'm using Python 2.7, and I keep getting an error about UTF-8 encoding? I don't know python, or bash, and am at a loss.

Re: Minetestmapper rewritten into C++

by wziard » Post

The colors.txt script is not by me, it's from (original) minetestmapper. However, it worked fine on my system I think.

However I can try to help. What system are you using to run it on? And what are the exact errors? Maybe better to send me a PM because it's not really on topic here.

Please may you give an example of this?

Edit: Also, the map that is produced by the generate leaflet script is blured when you zoom in, possibly due to JPEG. The nearest zoom should definitely use PNG

I was trying to update my isometric map after my summer holiday, and I noticed I had forgotten how everything works myself. :-D

So clearly better documentation and helper scripts are needed.

I'll try to write up how it works after I've figured it out myself again :-)

This probably has nothing to do with jpg vs png, but with zooming in further than level 0. At the default zoom level minetestmapper uses 1 pixel/block. If you zoom in so far that 1 block is more than 1 pixel on your screen your browser will start to interpolate between the pixels.

The solution is to use the --zoom option from minetestmapper to make the blocks somewhat larger. I tend to use '--zoom 4 '. This also leads to nicer isometric maps.
