直接从C#文件中加载字体 [英] Loading a font directly from a file in C#

问题描述

有没有办法做这样的事情?

Is there a way to do something like this?

FontFamily fontFamily = new FontFamily("C:/Projects/MyProj/free3of9.ttf");

我尝试了多种变体，但无法使其正常工作.

I've tried a variety of variations and haven't been able to get it to work.

更新:

这有效:

PrivateFontCollection collection = new PrivateFontCollection();
collection.AddFontFile(@"C:\Projects\MyProj\free3of9.ttf");
FontFamily fontFamily = new FontFamily("Free 3 of 9", collection);
Font font = new Font(fontFamily, height);

// Use the font with DrawString, etc.

推荐答案

此示例显示了如何从字节数组添加字体-如果字体存储在资源中.它也允许从文件中添加字体.我在winforms上使用的以下代码:

This example shows how to add font from byte array - if font is stored in resources. It allows to add font from file too. Following code I am using on winforms:

这有点棘手，要从文件中加载TTF字体，您需要执行以下操作:

It is little tricky, for loading TTF font from file you need to do this:

private PrivateFontCollection _privateFontCollection = new PrivateFontCollection();

public FontFamily GetFontFamilyByName(string name)
{
    return _privateFontCollection.Families.FirstOrDefault(x => x.Name == name);
}

public void AddFont(string fullFileName)
{
    AddFont(File.ReadAllBytes(fullFileName));
}   

public void AddFont(byte[] fontBytes)
{
    var handle = GCHandle.Alloc(fontBytes, GCHandleType.Pinned);
    IntPtr pointer = handle.AddrOfPinnedObject();
    try
    {
        _privateFontCollection.AddMemoryFont(pointer, fontBytes.Length);
    }
    finally
    {
        handle.Free();
    }
}
