有帮助吗?

解决方案

我知道的是,只有图书馆阅读字距调整信息“somwhat”正确的 iText的从Apache防

http://www.1t3xt.info/api /com/lowagie/text/pdf/BaseFont.html HTTP:/ /svn.apache.org/viewvc/xmlgraphics/fop/tags/fop-0_95/src/java/org/apache/fop/fonts/ (一的svn链接,因为似乎没有网上API)

其他提示

与Java SE 6开始,Java可以提供字距信息,该字体提供它。这是默认关闭,并且可以导通这样的:

Map<TextAttribute, Object> textAttributes = new HashMap<TextAttribute, Object>();  

textAttributes.put(TextAttribute.FAMILY, "Arial");  
textAttributes.put(TextAttribute.SIZE, 25f);  
textAttributes.put(TextAttribute.KERNING, TextAttribute.KERNING_ON);  

Font font = Font.getFont(textAttributes);  

这个论坛线程包含关于这一主题的更详细的讨论:

这是我在寻找字距信息和我的javascript中的离线提供它的方式,我在这里读了这个问题,也和因为没有答案,我搜索进一步上,并在年底,我得到这样的:

其可通过该字形的Unicode来索引两个JavaScript对象:

GLYPHS = {};
KERNS  = {};

和它们设置是这样的:

// GLYPHS[ unicode ] = [ "name", width ];
// KERNS [ unicode ] = { "nextGlyphName"        : horizontalAdjustment };
//                   = { GLYPHS[ unicode ][ 0 ] : horizontalAdjustment };

所以,如果我有我的“文本”的字符串,我通过它去逐个字符,用他的统一访问字形名和宽度是这样的:

glUnicode = "Text".charCodeAt( strIndex );            // "T" == 84
glName    = GLYPHS[ glUnicode ][ 0 ];
glWidth   = GLYPHS[ glUnicode ][ 1 ];

要访问字距调整值,我们来看看在下一字符的Unicode值,其是这样的:

nextGlyphUnicode = "Text".charCodeAt( strIndex + 1 ); // "e" == 101

和如果下列对象存在,那么该语句会给你字距宽度(你必须首先检查是否存在这样的:

if ( !( KERNS[ glUnicode ] == undefined ) ) {
  if ( !( KERNS[ glUnicode ][ GLYPHS[ nextGlyphUnicode ][ 0 ] ] == undefined ) ) {
  ...

):

kernWidth = KERNS[ glUnicode ][ GLYPHS[ nextGlyphUnicode ][ 0 ] ];

在这个例子中,对于kernWidth将 “e” 之后的 “T” 将是

kernWidth == -143

我想,这就是你要找的,对不对? 通过字符的Unicode值和以下字符的Unicode值访问的所有信息。 非常简单和非常好的。

因此,我创建的文件为每个字体和所述第一页面看起来像这样:

// Family Name
// 'Times New Roman'
// EM size
// '2048'
// is_quadratic
// '1'
//
// GLYPHS[ unicode ] = [ "name", width ];
// KERNS [ unicode ] = { "nextGlyphName"        : horizontalAdjustment };
//                   = { GLYPHS[ unicode ][ 0 ] : horizontalAdjustment };
GLYPHS = {};
KERNS  = {};

您可以复制的内容中的每个文件,你需要到您的源代码中或在运行时读取它拥有的对象availlable。

和文件可以与运行fontforge的“嵌入式”的Python 2.7解释器中细下面的脚本来创建。 这个脚本是专为Windows机器,所以你必须先适应你的路!

#
# run these two commands in the fontforge "embedded" python interpreter (ffpython.exe)
# >>> script = open( "Scripts\\Kernings.py", "r" )
# >>> exec script
