这是使用iText5读取PDF的代码,它可以正常工作:
public class CreateTOC {
public static final String SRC = "file.pdf";
class FontRenderFilter extends RenderFilter {
public boolean allowText(TextRenderInfo renderInfo) {
String font = renderInfo.getFont().getPostscriptFontName();
return font.endsWith("Bold") || font.endsWith("Oblique");
}
}
public static void main(String[] args) throws IOException, DocumentException {
new CreateTOC().parse(SRC);
}
public void parse(String filename) throws IOException {
PdfReader reader = new PdfReader(filename);
Rectangle rect = new Rectangle(1000, 1000);
RenderFilter regionFilter = new RegionTextRenderFilter(rect);
FontRenderFilter fontFilter = new FontRenderFilter();
TextExtractionStrategy strategy = new FilteredTextRenderListener(
new LocationTextExtractionStrategy(), regionFilter, fontFilter);
System.out.println(PdfTextExtractor.getTextFromPage(reader, 56, strategy));
reader.close();
}
}
有人可以帮助我在iText7中工作吗? Rectangle和TextExtractionStrategy存在问题(与iText5不同的构造函数)
编辑:RenderFilter在iText7中不可用...
