Delegate CustomFontSource

Navne til: Aspose.Imaging Sammensætning: Aspose.Imaging.dll (25.4.0)

Tilpasset font kildeudbyder

public delegate CustomFontData[] CustomFontSource(params object[] args)

Parameters

args object []

og argumenterne.

Returns

CustomFontData []

Listen over specifikke bogstaver for at gøre billedet

Examples

Dette eksempel viser den tilpassede font kilde, der giver brug af den specifikke font(er) til image rendering. I modsætning til FontSettings.SetFontsFolders metode fungerer i billedområdet og giver mulighed for at levere fontene i multi-bruger scenarier.
