使用iText / XMLWorker示例(大多数是 this one),我可以轻松编写能够使用我自己的额外字体从HTML代码创建PDF文件的简单应用程序,但是只要尝试在某些Web服务代码中使用我的东西,我就会以异常结束喜欢：
Table 'name' does not exist in file:/C:/work/MyServer/target/classes/fonts/My%20Font.ttf
ExceptionConverter: com.itextpdf.text.DocumentException: Table 'name' does not exist in file:/C:/work/MyServer/target/classes/fonts/My%20Font.ttf
…似乎指出在Web服务上下文中,无法按预期加载字体文件.这是我的大部分代码：
public HtmlRenderer(final String css, final String[] fontPaths) {
// fontPaths = {
// "/fonts/My Font.ttf",
// "/fonts/My Other Font.ttf",
// ...
// };
// CSS
cssResolver = new StyleAttrCSSResolver();
if (css != null) {
final CssFile cssFile = XMLWorkerHelper.getCSS(new ByteArrayInputStream(css.getBytes()));
cssResolver.addCss(cssFile);
}
// HTML
XMLWorkerFontProvider fontProvider = new XMLWorkerFontProvider(XMLWorkerFontProvider.DONTLOOKFORFONTS);
if (fontPaths != null) {
for (final String fontPath : fontPaths) {
final String path = this.getClass().getResource(fontPath).toExternalForm();
fontProvider.register(path);
}
}
CssAppliers cssAppliers = new CssAppliersImpl(fontProvider);
htmlContext = new HtmlPipelineContext(cssAppliers);
htmlContext.setTagFactory(Tags.getHtmlTagProcessorFactory());
...
我应该依赖这样的事情：
>从临时文件中的资源中提取字体(参见here)
>然后,在自定义字体工厂中预加载字体(参见there)
谢谢您的帮助！
