// between the two blocks, the 8 corners that aren't in common are the corners for the merged block

// note: e.g. if common face on block A is its top, the common face of block B is not necessarily the bottom face because blocks can be rotated differently

`PixiText @"[image]"` converts an image to text and places a text block with that text beside you. `Pixi @"[thing]"` to import `thing` into your Gamecraft game.
`PixiConsole @"[image]" "[text block id]"` converts an image to text and places a console block beside you which changes the specified text block.
`Pixi2D @"[image]"` converts an image to blocks and places it beside you.

It's important to include the file extension, since Pixi isn't capable of black magic (yet). It's important to include the file extension, since that's what makes Pixi's magic work.

`PixiBot @"[bot]"` downloads a bot from Robocraft's community Factory and places it beside you. `Pixi2 "[spell]" @"[thing]"` to use `spell` to import `thing` into your Gamecraft game.
`PixiBotFile @"[bot]"` converts a `.bot` file from [rcbup](https://github.com/NGnius/rcbup) to blocks and places it beside you. Some commands also have hidden features, like image rotation and bot scaling.

`PixiThicc [depth]` sets the block thickness, a positive integer value, for `Pixi2D` image conversion.

### Behaviour ### Behaviour
PixiText and PixiConsole share the same image conversion system. ImageText and ImageConsole share the same image conversion system.
The conversion system converts every pixel to a [color tag](http://digitalnativestudios.com/textmeshpro/docs/rich-text/#color) followed by a square text character. The conversion system converts every pixel to a [color tag](http://digitalnativestudios.com/textmeshpro/docs/rich-text/#color) followed by a square text character.
For PixiText, the resulting character string is set to the text field of the text block that the command places. For ImageText, the resulting character string is set to the text field of the text block that the command places.
For PixiConsole, the character string is automatically set to a console block in the form `ChangeTextBlockCommand [text block id] [character string]`. For ImageConsole, the character string is automatically set to a console block in the form `ChangeTextBlockCommand [text block id] [character string]`.
Due to limitations in Gamecraft, larger images will crash your game. Due to limitations in Gamecraft, larger images will crash your game!!!
Pixi2D takes an image file and converts every pixel to a coloured block. ImageCanvas takes an image file and converts every pixel to a coloured block.
Pixi2D uses an algorithm to convert each pixel in an image into the closest paint colour, but colour accuracy will never be as good as a regular image. ImageCanvas uses an algorithm to convert each pixel in an image into the closest paint colour, but colour accuracy will never be as good as a regular image.
Pixi2D's colour-conversion algorithm also uses pixel transparency so you can cut out shapes. ImageCanvas' colour-conversion algorithm also uses pixel transparency so you can cut out shapes.
A pixel which has opacity of less than 50% will be ignored. A pixel which has opacity of less than 50% will be ignored.
A pixel which has an opacity between 75% and 50% will be converted into a glass cube. A pixel which has an opacity between 75% and 50% will be converted into a glass cube.
A pixel which has an opacity greater than 75% will be converted into the block you're holding (or aluminium if you've got your hand selected). A pixel which has an opacity greater than 75% will be converted into the block you're holding (or aluminium if you've got your hand selected).
This only works with `.PNG` image files since the `.JPG` format doesn't support image transparency. This only works with `.PNG` image files since the `.JPG` format doesn't support image transparency.
Pixi2D also optimises block placement, since images have a lot of pixels. ImageCanvas also optimises block placement, since images have a lot of pixels.
The blocks grouping ratio is displayed in the command line output once image importing is completed. The blocks grouping ratio is displayed in the command line output once image importing is completed.
PixiBot and PixiBotFile convert a robot to equivalent Gamecraft blocks. RobocraftRobot converts a robot to equivalent Gamecraft blocks.
If the conversion algorithm encounters a block it cannot convert, it will place a text block, with the block name, instead. If the conversion algorithm encounters a block it cannot convert, it will place a text block, with the block name, instead.
