A Registry of 24x24 png images

This contract:

1. Stores all the classic traits of the CryptoPunks in individual png files, 100% on-chain. These are then used as blocks to construct CryptoPunk images. Outputted as SVGs.

2. Any of the 10,000 "classic" CryptoPunks can be generated by supplying desired arguments to a function, such as the id of a punk, or a list of the traits.

3. An unlimited number of new punk images can be generated from the existing classic set of traits, or even from new traits!

4. New traits (blocks) can be added to the contract by registering them with the registerBlock function.

Data Structures

Layer is in the order of rendering

    enum Layer {
        Base,      // 0 Base is the face. Determines if m or f version will be used to render the remaining layers
        Cheeks,    // 1 (Rosy Cheeks)
        Blemish,   // 2 (Mole, Spots)
        Hair,      // 3 (Purple Hair, Shaved Head, Pigtails, ...)
        Beard,     // 4 (Big Beard, Front Beard, Goat, ...)
        Eyes,      // 5 (Clown Eyes Green, Green Eye Shadow, ...)
        Eyewear,   // 6 (VR, 3D Glass, Eye Mask, Regular Shades, Welding Glasses, ...)
        Nose,      // 7 (Clown Nose)
        Mouth,     // 8 (Hot Lipstick, Smile, Buck Teeth, ...)
        MouthProp, // 9 (Medical Mask, Cigarette, ...)
        Earring,   // 10 (Earring)
        Headgear,  // 11 (Beanie, Fedora, Hoodie, Police Cap, Tiara, Headband, ...)
        Neck       // 12 (Choker, Silver Chain, Gold Chain)
    }

    struct Block {
        Layer layer;     // 13 possible layers
        bytes dataMale;  // male version of this attribute
        bytes dataFemale;// female version of this attribute
    }

Constructor

• constructor()

1 Transact Functions(s)

• function registerBlock(bytes _dataMale, bytes _dataFemale, uint8 _layer, string _name)

8 Query Functions(s)

• storage - mapping(bytes32 => Block) public blocks
  stores punk attributes as a png
• function getBlocks
  getBlocks returns a sequential list of blocks in a single call
  @param _fromID is which id to begin from
  @param _count how many items to retrieve.
  @return Block[] list of blocks, uint256 next id
• storage - mapping(uint256 => bytes32) public index
  index of each block by its sequence
• storage - uint256 public nextId
  next id to use when adding a block
• function svgFromIDs
  svgFromIDs returns the svg data as a string
  e.g. [9,55,99]
  One of the elements must be must be a layer 0 block.
  This element decides what version of image to use for the higher layers
  (dataMale or dataFemale)
  @param _ids uint256 ids of an attribute, by it's index of creation
• function svgFromKeys
  svgFromKeys returns the svg data as a string
  @param _attributeKeys a list of attribute names that have been hashed,
  eg keccak256("Male 1"), keccak256("Goat")
  must have at least 1 layer 0 attribute (eg. keccak256("Male 1")) which
  decides what version of image to use for the higher layers
  (dataMale or dataFemale)
  e.g. ["0x9039da071f773e85254cbd0f99efa70230c4c11d63fce84323db9eca8e8ef283",
  "0xd5de5c20969a9e22f93842ca4d65bac0c0387225cee45a944a14f03f9221fd4a"]
• function svgFromNames
  svgFromNames returns the svg data as a string
  @param _attributeNames a list of attribute names, eg "Male 1", "Goat"
  must have at least 1 layer 0 attribute (eg. Male, Female, Alien, Ape, Zombie)
  e.g. ["Male 1","Goat"]
  Where "Male 1" is a layer 0 attribute, that decides what version of
  image to use for the higher
  layers (dataMale or dataFemale)
• function svgFromPunkID
  svgFromPunkID returns the svg data as a string given a punk id
  @param _tokenID uint256 IDs a punk id, 0-9999
