是否可以在Java中将.jpg转换为.pdf?
尝试以下方法:
// pdf converter
Document document = new Document(PageSize.A4, 20, 20, 20, 20);
PdfWriter.getInstance(document, new FileOutputStream("C:\\ss.jpeg"));
document.open();
Image image = Image.getInstance(getClass().getResource("C:\\file.pdf"));
document.add(image);
document.close();
错误:无法对非静态方法进行静态引用 来自Object
类型的getClass()

使用 nameOfClass.class 代替 getClass()。
例如,请参阅以下代码段:
与您一样:
public class Test {
public static void main(String[] args) {
Document document = new Document(PageSize.A4, 20, 20, 20, 20);
PdfWriter.getInstance(document, new FileOutputStream("C:\\ss.jpeg"));
document.open();
Image image = Image.getInstance(getClass().getResource("C:\\file.pdf"));
document.add(image);
document.close();
}
}
将其更改为:
public class Test {
public static void main(String[] args) {
Document document = new Document(PageSize.A4, 20, 20, 20, 20);
PdfWriter.getInstance(document, new FileOutputStream("C:\\ss.jpeg"));
document.open();
Image image = Image.getInstance(Test.class.getResource("C:\\file.pdf"));
document.add(image);
document.close();
}
}

这对我有用。
public class CreatePDF {
public static void main (String args[]) {
Document document = new Document();
document.addAuthor("authorname");
document.addTitle("This is my pdf doc");
PdfWriter.getInstance(document, new FileOutputStream("C:\\file.pdf"));
document.open();
Image image = Image.getInstance("C:\\img.png");
document.add(image);
document.close();
}
}

public class ImageToPdf {
public static void main(String... args) {
Document document = new Document();
String input = "resources/GMARBLES.png"; // .gif and .jpg are ok too!
String output = "resources/GMARBLES.pdf";
try {
FileOutputStream fos = new FileOutputStream(output);
PdfWriter writer = PdfWriter.getInstance(document, fos);
writer.open();
document.open();
document.add(Image.getInstance(input));
document.close();
writer.close();
} catch (Exception e) {
e.printStackTrace();
}
}
}
