Examples
Creating a tag from a string and from individual characters:
var wghtFromString = SKFourByteTag.Parse("wght");
var wghtFromChars = new SKFourByteTag('w', 'g', 'h', 't');
Console.WriteLine(wghtFromString == wghtFromChars); // True
Console.WriteLine(wghtFromString); // wght
Remarks
`SKFourByteTag` is a read-only struct that wraps a 32-bit unsigned integer whose four bytes correspond to four ASCII characters. This matches the `SkFourByteTag` representation used throughout the Skia/OpenType APIs for table identifiers (e.g., `cmap`, `GSUB`) and variation axis tags (e.g., `wght`, `wdth`).
When constructed from four `char` values, the first character (`c1`) occupies the high byte and the last (`c4`) the low byte: `(c1 << 24) | (c2 << 16) | (c3 << 8) | c4`.
`Parse` accepts a string of 1–4 ASCII characters, right-padding with spaces if shorter than 4 characters.
`ToString` returns the four-character ASCII string representation.
Constructors
| Name | Description |
|---|---|
| SKFourByteTag(Char, Char, Char, Char) |
Initializes a new instance of the SKFourByteTag struct from four ASCII characters. |
| SKFourByteTag(UInt32) |
Initializes a new instance of the SKFourByteTag struct from a raw 32-bit value. |
Methods
| Name | Description |
|---|---|
| Equals(Object) |
Indicates whether this tag is equal to the specified object. |
| Equals(SKFourByteTag) |
Indicates whether this tag is equal to another SKFourByteTag. |
| GetHashCode() |
Returns a hash code for this tag. |
| Parse(String) |
Parses a string of up to four ASCII characters into an SKFourByteTag. |
| ToString() |
Returns the four-character ASCII string representation of this tag. |
Operators
| Name | Description |
|---|---|
| Equality(SKFourByteTag, SKFourByteTag) |
Determines whether two SKFourByteTag values are equal. |
| Implicit(SKFourByteTag to UInt32) |
Implicitly converts an SKFourByteTag to its underlying 32-bit unsigned integer value. |
| Implicit(UInt32 to SKFourByteTag) |
Implicitly converts a 32-bit unsigned integer to an SKFourByteTag. |
| Inequality(SKFourByteTag, SKFourByteTag) |
Determines whether two SKFourByteTag values are not equal. |
