我需要在Android上使用iText的帮助。我正在创建PDF,并需要它显示诸如ā,ū,ē,ķ,č等字符。这是我用来创建自定义字体的代码。
BaseFont bf;
{
try {
bf = BaseFont.createFont("c:/windows/fonts/CAMBRIA.TTC", BaseFont.IDENTITY_H, BaseFont.EMBEDDED);
} catch (DocumentException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
Font smallFont = new Font(bf, 12);
这是我如何使用它的示例。
PdfPTable table_start = new PdfPTable(3);
PdfPCell name = new PdfPCell(new Paragraph("Objekts: " + view0.getText().toString(), smallFont));
当我在视图中显示从其他活动获得的字符串时,文本看起来很正常,但是在创建PDF时,所有特殊字符都消失了。

请按照以下步骤操作:
formattedMsg = ANSIObj.ConvertToANSIText(outletObj.banglaName);
public String Convert(String line) throws UnsupportedEncodingException {
//Your conversion Code
return line;
}
public void CreateBanglaMemoTableFormat(List<PDFTableData> items) {
Document doc = new Document(PageSize.A4.rotate());
try {
setYourFont();
doc = new Document(new Rectangle(818.3f, 609f));
String path = Environment.getExternalStorageDirectory().getAbsolutePath() + "/MyPDF";
File dir = new File(path);
if (!dir.exists())
dir.mkdirs();
File file = new File(dir, "newPDFFile.pdf");
FileOutputStream fOut = new FileOutputStream(file);
PdfWriter.getInstance(doc, fOut);
//open the document
doc.open();
Paragraph p1 = new Paragraph();
p1.setAlignment(Paragraph.ALIGN_LEFT);
p1.setFont(f_textFont);
p1.add(formattedMsg);
PdfPTable tt = masteraTableCreation(p1);
doc.add(tt);
}
} catch (DocumentException de) {
Log.e("PDFCreator", "DocumentException:" + de);
} catch (IOException e) {
Log.e("PDFCreator", "ioException:" + e);
} finally {
doc.close();
}
}
public void setYourFont() throws DocumentException, IOException {
try {
bf = BaseFont.createFont("/fontname", BaseFont.IDENTITY_H, BaseFont.EMBEDDED);
f_textFont = new Font(bf, 10);
} catch (Exception ex) {
ex.printStackTrace();
}
}
private PdfPTable masteraTableCreation(Paragraph celV1) {
float[] columnWidths = {236};
PdfPTable mainTable = new PdfPTable(columnWidths);
mainTable.getDefaultCell().setPaddingRight(5);
mainTable.setTotalWidth(786f);
mainTable.setLockedWidth(true);
PdfPCell cell;
//region Row 1
// column 1
cell = new PdfPCell(new Phrase(celV1));
cell.setBorder(Rectangle.NO_BORDER);
mainTable.addCell(cell);
return mainTable;
}

答案实际上非常简单。我要做的就是在资产文件夹中放置一个支持Unicode字符的字体,然后进行更改:
library(colorspace)
df <- matrix(c(20, 14, 26, 18, 14, 4, 19, 21, 13, 1, 5, 4), ncol = 4, byrow = TRUE)
rownames(df) <- c("Character", "Tree", "Distance")
colnames(df) <- c("nrITS", "trnH-\npsbA", "matK", "rbcL")
graph.dat <- as.table(df)
italic_latin2 <- c(expression(atop(italic("nrITS"), (104))),
expression(atop(italic("trnH-\npsbA"), (82))),
expression(atop(italic("matK"), (42))),
expression(atop(italic("rbcL"), (28))))
barplot(graph.dat, beside = TRUE, ylab = "Percent Identified",
xlab = "Locus", ylim = c(0, 30), col = rainbow_hcl(3),
names.arg = italic_latin2)
到
bf = BaseFont.createFont("c:/windows/fonts/CAMBRIA.TTC", BaseFont.IDENTITY_H, BaseFont.EMBEDDED);

我在调用 BaseFont.createFont API 时在编码参数中使用了 BaseFont.IDENTITY_H 并且它起作用了。
