使用itext java编写pdf格式的心形符号
试图通过java代码在pdf中编写心形符号。 这是我对pdf的输入:❤️❤️❤️
但生成的pdf是空的,没有任何内容。 使用itext写入pdf。 使用的字体是tradegothic_lt_BoldCond20。ttf
OutputStream file = new FileOutputStream(fileName);
Document document = new Document(PageSize.A6);
PdfWriter writer = PdfWriter.getInstance(document, file);
document.open();
PdfLayer nested = new PdfLayer("Layer 1", writer);
PdfContentByte cb = writer.getDirectContent();
cb.beginLayer(nested);
ColumnText ct = new ColumnText(cb);
Font font = getFont();
Phrase para1 = new Phrase("❤️❤️❤️",font);
ct.setSimpleColumn(para1,38,0,260,138,15, Element.ALIGN_LEFT);
ct.go();
cb.endLayer();
document.close();
file.close();
private Font getFont() {
final String methodName = "generatePDF";
LOGGER.entering(CLASSNAME, methodName);
Font font = null;
try {
String filename = tradegothic_lt_boldcondtwenty.ttf;
FontFactory.register(filename, filename);
font = FontFactory.getFont(filename, BaseFont.CP1252, BaseFont.EMBEDDED,11.8f);
} catch(Exception exception) {
LOGGER.logp(Level.SEVERE, CLASSNAME, methodName, "Exception Occurred while fetching the Trade Gothic font." + exception);
font = FontFactory.getFont(FontFactory.HELVETICA_BOLD,11.8f);
}
return font;
}
短语para1的心脏是正确的。但无法在pdf中查看
