### Load and Apply Paramdefs to Params

Source: https://github.com/soulsmods/soulsformatsnext/blob/master/FORMATS.md

Loads parameters from a parambnd archive and applies paramdefs using a careful method to ensure compatibility. Includes editing and saving param data.

```cs
var parms = new Dictionary<string, PARAM>();
var parambnd = BND3.Read(path);
foreach (BinderFile file in parambnd.Files)
{
	string name = Path.GetFileNameWithoutExtension(file.Name);
	var param = PARAM.Read(file.Bytes);
	
	// Recommended method: checks the list for any match, or you can test them one-by-one
	if (param.ApplyParamdefCarefully(paramdefs))
		parms[name] = param;
	
	// Alternative method: applies without any additional verification
	param.ApplyParamdef(paramdefs.Find(def => def.ParamType == param.ParamType));
	parms[name] = param;
}

// Editing param data
PARAM weapons = parms["EquipParamWeapon"];
// Paramdef must be supplied to new rows in order to initialize cells correctly
weapons.Rows.Add(new PARAM.Row(9900000, "My Super Cool Weapon", weapons.AppliedParamdef));
// Be mindful of the correct value type for each cell
weapons[9900000]["weight"].Value = 100f;

// Save each param, then the parambnd
foreach (BinderFile file in parambnd.Files)
{
	string name = Path.GetFileNameWithoutExtension(file.Name);
	if (parms.ContainsKey(name))
		file.Bytes = parms[name].Write();
}
parambnd.Write(path);
```

### Read BND3 from File Path or Byte Array

Source: https://github.com/soulsmods/soulsformatsnext/blob/master/README.md

Use the static Read method to create BND3 objects. Providing a file path is preferred for reduced memory consumption.

```cs
BND3 bnd = BND3.Read(@"C:\your\path\here.chrbnd");

// or

byte[] bytes = File.ReadAllBytes(@"C:\your\path\here.chrbnd");
BND3 bnd = BND3.Read(bytes);
```

--------------------------------

### Read Custom XML Paramdefs

Source: https://github.com/soulsmods/soulsformatsnext/blob/master/FORMATS.md

Loads custom parameter definitions from XML files. Useful for games or modifications that do not ship with official paramdefs.

```cs
var paramdefs = new List<PARAMDEF>();
foreach (string path in Directory.GetFiles(dir, "*.xml"))
{
	var paramdef = PARAMDEF.XmlDeserialize(path);
	paramdefs.Add(paramdef);
}
```

### Compressing DCX with Specific Type

Source: https://github.com/soulsmods/soulsformatsnext/blob/master/README.md

When writing a new DCX file, a DCX.Type parameter is required to indicate the target game. DCX.Decompress can output the detected type.

```cs
byte[] bndBytes = DCX.Decompress(@"C:\your\path\here.chrbnd.dcx", out DCX.Type type);
DCX.Compress(bndBytes, type, @"C:\your\path\here.chrbnd.dcx");

// or

byte[] bndBytes = DCX.Decompress(@"C:\your\path\here.chrbnd.dcx", out DCX.Type type);
byte[] dcxBytes = DCX.Compress(bndBytes, type);
File.WriteAllBytes(@"C:\your\path\here.chrbnd.dcx", dcxBytes);
```

--------------------------------

### Read and Write DCX Compressed Files

Source: https://github.com/soulsmods/soulsformatsnext/blob/master/README.md

DCX files are automatically decompressed upon reading and compression is reapplied upon writing. The compression type is remembered.

```cs
BND3 bnd = BND3.Read(@"C:\your\path\here.chrbnd.dcx");
bnd.Write(@"C:\your\path\here.chrbnd.dcx");
```

--------------------------------

### Generic DCX Decompression and Compression

Source: https://github.com/soulsmods/soulsformatsnext/blob/master/README.md

DCX files can be generically decompressed and compressed using static methods, operating directly on byte arrays.

```cs
byte[] bndBytes = DCX.Decompress(@"C:\your\path\here.chrbnd.dcx");
BND3 bnd = BND3.Read(bndBytes);

// or

byte[] dcxBytes = File.ReadAllBytes(@"C:\your\path\here.chrbnd.dcx");
byte[] bndBytes = DCX.Decompress(dcxBytes);
BND3 bnd = BND3.Read(bndBytes);
```

--------------------------------

### Write BND3 to File Path or Byte Array

Source: https://github.com/soulsmods/soulsformatsnext/blob/master/README.md

The Write method creates a new file from a BND3 object. It can write to a specified path or return a byte array.

```cs
bnd.Write(@"C:\your\path\here.chrbnd");

// or

byte[] bytes = bnd.Write();
File.WriteAllBytes(@"C:\your\path\here.chrbnd", bytes);
```

--------------------------------

### Read Original Paramdefbnd

Source: https://github.com/soulsmods/soulsformatsnext/blob/master/FORMATS.md

Reads original binary paramdef files from a BND3 archive. Ensures proper parsing of game-specific parameter definitions.

```cs
var paramdefs = new List<PARAMDEF>();
var paramdefbnd = BND3.Read(path);
foreach (BinderFile file in paramdefbnd.Files)
{
	var paramdef = PARAMDEF.Read(file.Bytes);
	paramdefs.Add(paramdef);
}
```

--------------------------------

### Change DCX Compression Type

Source: https://github.com/soulsmods/soulsformatsnext/blob/master/README.md

Modify the compression type by setting the Compression field or specifying it during the Write operation.

```cs
BND3 bnd = BND3.Read(@"C:\your\path\here.chrbnd.dcx");
bnd.Write(@"C:\your\path\here.chrbnd", DCX.Type.None);

// or

BND3 bnd = BND3.Read(@"C:\your\path\here.chrbnd.dcx");
bnd.Compression = DCX.Type.None;
bnd.Write(@"C:\your\path\here.chrbnd");
```
