Methods

CanRender(SKTypeface, int)

public bool CanRender(SKTypeface typeface, int character)

Parameters

typeface SKTypeface

character int

bool

ClearCharacterCache()

Clears the character-to-typeface cache. Call this if fonts are dynamically loaded/unloaded at runtime.

public static void ClearCharacterCache()

DetectUnicodeBlock(int)

public static UnicodeBlock DetectUnicodeBlock(int codePoint)

Parameters

codePoint int

Unicode code point

Returns

UnicodeBlock

Unicode block category

FindBestTypefaceForString(string)

public static (SKTypeface, int) FindBestTypefaceForString(string text)

Parameters

text string

Returns

(SKTypeface, int)

GetAlias(string, FontWeight)

public static string GetAlias(string alias, FontWeight weight)

Parameters

alias string

weight FontWeight

Returns

string

GetAlias(string, int)

public static string GetAlias(string alias, int weight)

Parameters

alias string

weight int

Returns

string

GetCharacterCacheSize()

Gets the current size of the character cache for diagnostics.

public static int GetCharacterCacheSize()

Returns

int

GetEmbeddedResourceNames()

Get the list of all emdedded resources in the assembly.

public static string[] GetEmbeddedResourceNames()

Returns

string[]

An array of fully qualified resource names

GetEmbeddedResourceStream(Assembly, string)

public static Stream GetEmbeddedResourceStream(Assembly assembly, string resourceFileName)

Parameters

assembly Assembly

resourceFileName string

Returns

Stream

GetEmbeddedResourceStream(string)

Takes the full name of a resource and loads it in to a stream.

public static Stream GetEmbeddedResourceStream(string resourceName)

Parameters

resourceName string

Assuming an embedded resource is a file called info.png and is located in a folder called Resources, it will be compiled in to the assembly with this fully qualified name: Full.Assembly.Name.Resources.info.png. That is the string that you should pass to this method.

Returns

Stream
