The CreateFromImage command is used to build terrain from large heightmaps. Heightmaps can be generated using software like WorldMachine and GeoGlyph or found online.

Examples (vanilla blocks):

Dependencies:

PlotSquared (dev build) with enabled-components.worlds set to true
Put any jars with textures you want (e.g. your .minecraft/versions/<version>/<version>.jar) in FastAsyncWorldEdit/textures

Command Syntax

<arg> - A required parameter
[arg] - An optional parameter
<arg1|arg2> - Multiple parameters options
<arg=value> - Default or suggested value

Terminology

Height Map - The HSL luminance (whiteness) of each pixel represents the terrain height.
Color Map - An image of terrain color
Image Mask - Restrict some operation to the white parts of the image mask

Starting

To begin you need to either specify a heightmap to use, or the dimensions you want.

Using a heightmap: //cfi <url>
Or using a fixed size: //cfi <width> <length>

Do not run these yet, but when you are happy with your settings:

//cfi done - Build the world
//cfi cancel - Cancel creation

Modifying the world

The palette

You may want to color the world using an image e.g. https://i.imgur.com/TlH2uhU.jpg
Before you color parts of the world, you should change your palette (coloring) settings.

`//cfi paletteComplexity <min=0> <max=100>`

Filter out blocks to use based on their complexity, which is a measurement of how much color variation there is in the texture for that block.
Glazed terracotta is complex, and not very pleasant for terrain, whereas stone and wool are simpler textures.
Using 0 73 for the min/max would use the simplest 73% of blocks for coloring, and is a reasonable value.

`//cfi paletteRandomization <enabled=true>`

This is enabled by default, randomization will add some random variation in the blocks used to closer match the provided image.
If disabled, the closest block to the color will always be used.
Randomization will allow mixing biomes when coloring with biomes

`//cfi paletteBlocks <mask|#clipboard>`

Allow only specific blocks to be used for coloring
block-list is a list of blocks e.g. stone,bedrock,wool
#clipboard will only use the blocks present in your clipboard.

`//cfi paletteBiomePriority <percent=50>`

Increase or decrease biome priority when using blockBiomeColor.
A value of 50 is the default
Above 50 will prefer to color with biomes
Below 50 will prefer to color with blocks

Coloring commands

`//cfi color <image-url> [image-mask|mask] [whiteOnly=true]`

Color the terrain using only blocks
Provide an image, or worldedit mask for the 2nd argument to restrict what areas are colored
whiteOnly will restrict coloring to the white parts of the image mask (if provided)

`//cfi glass <image-url>`

Color the terrain using glass (unique, but looks weird from an angle)

`//cfi biomeColor <image-url>`

Color the terrain using biomes.

Note: Biome coloring does not change blocks:

If you changed the block to something other than grass you will not see anything.

`//cfi blockBiomeColor <image-url> [image-mask|mask] [whiteOnly=true]`

Color the terrain using blocks and biomes.
Provide an image, or worldedit mask for the 2nd argument to restrict what areas are colored
whiteOnly will restrict coloring to the white parts of the image mask (if provided)

`//cfi biome [url|mask] <biome> [whiteOnly=false]`

Set the biome in specific parts of the map.

If an image is used, the biome will have a chance to be set based on how white the pixel is (white #FFF = 100% chance)
The whiteOnly parameter determines if only white values on the image are set
If a mask is used, the biome will be set anywhere the mask applies

Height settings

`//cfi height <url|height>`

Set the terrain height either based on an image heightmap, or a numeric value.

`//cfi waterHeight <height=0>`

Change the level water is generated at.
By default water is disabled (with a value of 0)

`//cfi waterId <number-id>`

Use another block id instead of water. e.g Maybe you want to use lava.

`//cfi smooth <image-mask|mask> <radius> <iterations> [whiteonly=true]`

Smooth terrain within an image-mask, or worldedit mask
You can use !0 as the mask to smooth everything
This supports smoothing snow layers (set the floor to 78:7)
A good value for radius and iterations would be 1 8.

Material settings

`//cfi overlay [url|mask] <pattern> [white=false]`

Change the block directly above the floor (default: air)
e.g. Tallgrass

`//cfi main [url|mask] <pattern> [white=false]`

Change the block to use as filling (default: stone)

`//cfi floor [url|mask] <pattern> [white=false]`

Change the block to use as the floor (default: grass)

`//cfi column [url|mask] <pattern> [white=false]`

Change both the floor and main block.

Populators

`//cfi caves`

Generate vanilla caves

`//cfi ore[s]`

`//cfi addores`

Add the default minecraft ores.

`//cfi ore <mask> <pattern> <size> <frequency> <rarity> <min-Y> <max-Y>`

Use a specific pattern and settings to generate ore.

`//cfi schem [url] <mask> <file|folder|url> <rarity> <distance> <rotate>`

Populate a schematic on the terrain.
Change the mask (e.g. angle mask) to only place the schematic in specific locations.
The rarity is a value between 0 and 100.
