问题描述
我使用的生成PDF droidText liberary
I am generating pdf using droidText liberary
我有以下的code
public void createPDF()
{
Document doc = new Document();
try {
String path = Environment.getExternalStorageDirectory().getAbsolutePath() + "/droidText";
File dir = new File(path);
if(!dir.exists()){
System.out.println("directory not exists");
dir.mkdirs();
}else{
System.out.println("directory exirsts");
}
System.out.println("path="+path);
Log.d("PDFCreator", "PDF Path: " + path);
File file = new File(dir, "sample.pdf");
FileOutputStream fOut = new FileOutputStream(file);
PdfWriter.getInstance(doc, fOut);
//open the document
doc.open();
Paragraph p1 = new Paragraph("Hi! I am generating my first PDF using DroidText");
Font paraFont= new Font(Font.COURIER);
p1.setAlignment(Paragraph.ALIGN_CENTER);
p1.setFont(paraFont);
//add paragraph to document
doc.add(p1);
Paragraph p2 = new Paragraph("This is an example of a simple paragraph");
Font paraFont2= new Font(Font.COURIER,14.0f,Color.GREEN);
p2.setAlignment(Paragraph.ALIGN_CENTER);
p2.setFont(paraFont2);
doc.add(p2);
//
//set footer
Phrase footerText = new Phrase("This is an example of a footer");
HeaderFooter pdfFooter = new HeaderFooter(footerText, false);
doc.setFooter(pdfFooter);
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(Uri.fromFile(file),"application/pdf");
intent.setFlags(Intent.FLAG_ACTIVITY_NO_HISTORY);
startActivity(intent);
} catch (DocumentException de) {
Log.e("PDFCreator", "DocumentException:" + de);
} catch (IOException e) {
Log.e("PDFCreator", "ioException:" + e);
}
finally
{
doc.close();
}
}
它的工作原理..但是当我使用下列行添加图片到它,它说:该方法getInstance(byte []的)是不确定的该类型文件
it works.. but when I add Image to it using following lines, it says "The method getInstance(byte[]) is undefined for the type Document"
ByteArrayOutputStream stream = new ByteArrayOutputStream();
Bitmap bitmap = BitmapFactory.decodeResource(getBaseContext().getResources(), R.drawable.ic_launcher);
bitmap.compress(Bitmap.CompressFormat.JPEG, 100 , stream);
Image myImg = Image.getInstance(stream.toByteArray());
//myImg.setAlignment(Image.MIDDLE);
add image to document
doc.add(myImg);
帮助我将图像添加到文档
help me in adding images to the document
推荐答案
按 Document.java ,那类没有一个getInstance方法。 你想 Image.getInstance 按本的StackOverflow问题,
As per Document.java, that class doesn't have a getInstance method. You want Image.getInstance as per this StackOverflow question,
例如。
Image myImg = Image.getInstance(stream.toByteArray());
doc.add(myImg);
这是不是一个重复的问题,但确实有这回答了你的发言回答帮我在将图像添加到文档
which isn't a duplicate question but does have an answer which answers your statement of "help me in adding images to the document"
