Image is not generating

[pr20080798]

Hi Team ,

I have written code to add image in the Document by passing byte value,facing below mentioned exception.

CODE :
byte[] content=[B@31ff6309
if(null != content) {
paragraph = section.addParagraph();
paragraph.getFormat().setLeftIndent(50);
DocPicture picture = new DocPicture(document);
// picture.loadImage(imagePath);
picture.setWidth(50);
picture.setHeight(90);
picture.setTextWrappingStyle( TextWrappingStyle.Tight);
paragraph.appendPicture(content);
}

EXCEPTION :
Exception in thread "main" java.lang.NullPointerException: Image bytes cannot be null or empty
at com.spire.doc.fields.DocPicture.loadImage(Unknown Source)
at com.spire.doc.documents.Paragraph.appendPicture(Unknown Source).

Hi,

Thank you for your inquiry.
According to the message you provided, I can't reproduce your issue.However, you can add image to the document in bytes using the following two methods.
Method 1:

Code: Select all

  Document document = new Document();
        //Load Image Bytes
        String imagePath = "data/1.png";
        FileInputStream imageStream = new FileInputStream(imagePath);
        Section section = document.addSection();
        byte[] content = new byte[imageStream.available()];
        imageStream.read(content);
        //if the content is not empty and add it to the document
        if (content != null) {
            Paragraph paragraph = section.addParagraph();
            paragraph.getFormat().setLeftIndent(50);
            DocPicture picture = new DocPicture(document);
            picture.loadImage(content);
            picture.setWidth(50);
            picture.setHeight(90);
            picture.setTextWrappingStyle(TextWrappingStyle.Tight);
            paragraph.getChildObjects().insert(0,picture);
 }
        //Save Document
        FileOutputStream fileOutputStream = new FileOutputStream("output/document.docx");
        document.saveToStream(fileOutputStream, FileFormat.Docx);
        //Close Stream
        fileOutputStream.close();
        imageStream.close();
        document.close();


Method 2:

Code: Select all

 Document document = new Document();
        //Load Image Bytes
        String imagePath = "data/1.png";
        FileInputStream imageStream = new FileInputStream(imagePath);
        Section section = document.addSection();
        byte[] content = new byte[imageStream.available()];
        imageStream.read(content);
        //if the content is not empty and add it to the document
        if (content != null) {
            Paragraph paragraph = section.addParagraph();
            paragraph.getFormat().setLeftIndent(50);
            paragraph.appendPicture(content);
}
        //Save Document
        FileOutputStream fileOutputStream = new FileOutputStream("output/document1.docx");
        document.saveToStream(fileOutputStream, FileFormat.Docx);

        //Close Stream
        fileOutputStream.close();
        imageStream.close();
        document.close();


If my code doesn’t help you, please offer your test file and image to help us do further investigation, you can attach here or send it to us via email ([email protected]). Thank you in advance.
