问题描述
我有一个 HTML 页面，我想用 iText7 将其转换为 PDF。那行得通，只有表格布局不等于 HTML 版本。
原始HTML布局（仅相关部分）：
现在是创建的 PDF 文件。请检查'Oracle-JRE-8 (...)'之前的部分：
td 宽度不同。表格宽度=100%，第一列是20%，第二列是80%。
这是我用来创建 PDF 文件的 PowerShell 代码。

解决方法
发生这种情况是因为前三个表格中某些单元格的最小宽度很大。表格不适合页面区域，因此宽度超出预期。当我们减小显示宽度时，这种效果也存在于 HTML 中：https://i.stack.imgur.com/nFmiC.png。
为避免这种情况，您可以选择以下选项之一：
-
更改输出文档页面大小或页面方向：
PdfDocument pdfDocument = new PdfDocument(new PdfWriter(new FileInfo(outFilename))); pdfDocument.SetDefaultPageSize(PageSize.A3); // pdfDocument.SetDefaultPageSize(PageSize.A4.Rotate()); HtmlConverter.ConvertToPdf(new FileStream(srcFilename,FileMode.Open),pdfDocument); -
使用一张桌子而不是几张桌子。
-
使用 font-size 减小内容的大小。例如，您可以将表格元素的字体大小设置为 14 像素。
前三个表中导致最小宽度问题的单元格包含单行文本，文件路径包含许多 '' 字符。因此，另一个选项可以是按此字符拆分文本。您可以为此使用此代码示例（在 Java 上）：
public static void main(String[] args) {
ConverterProperties cp = new ConverterProperties();
cp.setCssApplierFactory(new CustomCssApplierFactory());
HtmlConverter.convertToPdf(new File(srcFilename),new File(outFilename),cp);
}
private static class CustomCssApplierFactory implements ICssApplierFactory {
private ICssApplierFactory defaultCssApplierFactory = new DefaultCssApplierFactory();
@Override
public ICssApplier getCssApplier(IElementNode tag) {
ICssApplier defaultCssApplier = defaultCssApplierFactory.getCssApplier(tag);
return defaultCssApplier != null ? new CustomCssApplier(defaultCssApplier) : null;
}
}
private static class CustomCssApplier implements ICssApplier {
private final ICssApplier defaultCssApplier;
public CustomCssApplier(ICssApplier defaultCssApplier) {
this.defaultCssApplier = defaultCssApplier;
}
@Override
public void apply(ProcessorContext context,IStylesContainer stylesContainer,ITagWorker tagWorker) {
defaultCssApplier.apply(context,stylesContainer,tagWorker);
IPropertyContainer elementResult = tagWorker.getElementResult();
if (elementResult != null) {
setCustomSplitCharacter(elementResult);
} else if (tagWorker instanceof SpanTagWorker) {
// If current element is span,then set the custom split character to nested elements
for (IPropertyContainer ownLeafElement : ((SpanTagWorker) tagWorker).getOwnLeafElements()) {
setCustomSplitCharacter(ownLeafElement);
}
}
}
private void setCustomSplitCharacter(IPropertyContainer elementResult) {
// If Property.SPLIT_CHARACTERS was null then DefaultSplitCharacters class would be used during layout.
Object property = elementResult.getProperty(Property.SPLIT_CHARACTERS);
// BreakAllSplitCharacters and KeepAllSplitCharacters instances can be set
// if CSS word-break property was applied.
if (!(property instanceof BreakAllSplitCharacters)) {
elementResult.setProperty(Property.SPLIT_CHARACTERS,new CustomSlashSplitCharacters());
}
}
}
private static class CustomSlashSplitCharacters extends DefaultSplitCharacters {
private static final String SPLIT_CHARACTER = "\\";
@Override
public boolean isSplitCharacter(GlyphLine text,int glyphPos) {
Glyph glyph = text.get(glyphPos);
return glyph.hasValidUnicode() && SPLIT_CHARACTER.equals(glyph.getUnicodeString())
|| super.isSplitCharacter(text,glyphPos);
}
}
