Installation

• Install .NET 6.x
• Download latest release

Usage

1. First see available worlds and maps

   > .\DynmapImageExport list <url>
   
   Example:
   > .\DynmapImageExport ls https://map.minecrafting.ru/
   List for: https://map.minecrafting.ru/
   Available worlds and maps
   ├── world - Верхний мир
   │   ├── flat    Плоский
   │   └── se_view 3D юго-восток
   ...
   

2. Then available zoom levels

   > .\DynmapImageExport info <url> <world> <map>
   
   Example:
   > .\DynmapImageExport i https://map.minecrafting.ru/ world flat
   Info for: https://map.minecrafting.ru/ - world - flat
   World: world - Верхний мир
   Map: flat - Плоский
   Perspective: iso_S_90_lowres PPB: 4
   Zoom levels
   ├── 0 - 4:1
   ├── 1 - 2:1
   ├── 2 - 1:1
   ├── 3 - 1:2
   ├── 4 - 1:4
   ├── 5 - 1:8
   └── 6 - 1:16
   

3. Make a image

   > .\DynmapImageExport merge <url> <world> <map> [<point>...] [options]
   
   Example:
   > .\DynmapImageExport m https://map.minecrafting.ru/ world flat [0,100,0] -p [6,6,5,5] -z 2
   

Used arguments:

• https://map.minecrafting.ru/ - Dynmap HTTP server
• world - World name
• flat - Map name
• [0,100,0] - Minecraft coordinates of point.
• -p [6,6,5,5] - Padding in tiles from points. 6 to top, 6 to right, 5 to bottom, 5 to left.
  This will produce 12x12 tiles image(1536x1536 in pixels)
• -z 2 - Zoom level. 1:1 scale in this example.

Notes

• Executing without arguments will launch in interactive mode
• Default zoom is 1:1 scale (i.e. 1 block to 1 pixel)
• Size of 10Kpx X 10Kpx image ~= 150MB; 20Kpx X 20Kpx ~= 450MB

Points and Padding example

You can provide any number of points. They will be combined into a region. Padding will be added to the resulting region.

• [2] - 2 in each direction
• [2,3] - 2 to top and bottom, 3 to right and left
• [2,3,2,2] - 2 to top, 3 to right, 2 to bottom, 2 to left

One point with padding [1,2,3,2]

Three points with padding [1]
