p:image is not working for me

[pramanish]

Hi all,

i want to place an image inside the pdf document for what i have written following xhtml code :

<p:document xmlns:p="http://jboss.com/products/seam/pdf" >
     <p:image alignment="left" wrap="true" value="/test/test1/images/headlogo.gif" />                                                    
            <p:font size="24">
             <p:paragraph spacingAfter="50">Fax Cover Page</p:paragraph>
         </p:font>       
       <p:barCode type="code128"
           barHeight="80"
           textSize="20"
           code="(10)45566(17)040301"
           codeType="code128"
           altText="My BarCode" />                                                       </p:document>

But i am getting following exception:

Please any body can help me to resolve this problem.

Help will be appreciable.

Thanks in advace.

It can't find your image headlogo.gif.  Looks like you might be referencing some external file?   A simple fix to get you going might be to place the image file in the same location as the xhtml file, then you can determine where it really needs to be.  A better approach might be to load the image in your seam component, and then reference the byte array in the p:image component. 

[oneilltg]

How do you go about using a byte array? I tried the following:

<p:image value="#{arInvoiceBB.bytes}"/>

And my backing bean has:


public byte[] getBytes() throws AluaException, MalformedURLException, FileNotFoundException, IOException {

        File logoFile = new File(imageLocation + LogoScreenBB.LOGO_FILE_NAME);
        InputStream is = new FileInputStream(logoFile);

        // Get the size of the file
        long length = logoFile.length();
        log.info("length of file: " + length);

        if (length > Integer.MAX_VALUE) {
            log.warn("file too big!");
        }

        // Create the byte array to hold the data
        byte[] bytes = new byte[(int)length];

        // Read in the bytes
        int offset = 0;
        int numRead = 0;
        while (offset < bytes.length
               && (numRead=is.read(bytes, offset, bytes.length-offset)) >= 0) {
            offset += numRead;
        }

        // Ensure all the bytes have been read in
        if (offset < bytes.length) {
            throw new IOException("Could not completely read file "+logoFile.getName());
        }

        // Close the input stream and return bytes
        is.close();
        log.info("returning byte array");
        return bytes;
    }

I end up with a null pointer though.

Any advice? We are trying to display a logo that we are allowing our users to upload to our file system.

Ok, got it working. Turns out that p:image wants a ByteARrayInputStream, not a byte[]. So I added these two methods to my backing bean:

public ByteArrayInputStream getLastTry() throws AluaException, MalformedURLException, IOException, FileNotFoundException
     {
         log.info("In getLastTry");
         return getAwtImage(getBytes());
     }

     public ByteArrayInputStream getAwtImage(byte[] data) {
        log.info("In getAwtImage");
        ByteArrayInputStream inStream = new ByteArrayInputStream(data);
        ByteArrayOutputStream outStream = new ByteArrayOutputStream();
        try {
            BufferedImage image = ImageIO.read(inStream);
            ImageIO.write(image, "jpeg", outStream);
            log.info("Just used ImageIO to write to the outstream");
            outStream.close();
        } catch (IOException e) {

            e.printStackTrace();
        }
        return new ByteArrayInputStream(outStream.toByteArray());
     }


And my xhtml has:  <p:image value="#{arInvoiceBB.lastTry}"/>

[mdesignz]

Returning byte[] works for me in Seam 2.1.2.CR2

[oneilltg]

Interesting. I'm on 2.1.1, but I don't see anything in the 2.1.2 release notes that implies this has changed. I won't rule out user error on my part.

Hi,

I ran into what seems to be very closely related to the issue discussed here. I have PDF generation going on, and I am trying to insert a image into a cell within a table. I'm using a rather old version of seam (1.2.1) -- no much room to move on to a new version at this point, old app, stable, and it works --

I have already tried all the possible combinations I could think of, including the above with a slightly different variation, instead of a ByArrayInputStream I am passing a Image (awtImage) to the p:image component, alternatively I have also attempted loading the image from the hard drive, but that also didn't have any effect

the report I generate uses a log at the top, and that works just fine, I seem to be stuck 'only' with the scenario where I try to add the image into a cell / table

if anyone has had any experience with this, it would be of great help

thank you
a

[arronlee]

Hi, mom image.

I agree with you that using another java code 128 barcode generatior whose way of processing is simple and fast can make all the process much more convenient to operate. And I am also testing baout the related progarmmes recently. W e can communicate about it later. Good luck.

Best regards,

Arron

Thank you so much, I tried to search the resolutions on google, but most are useless. Your suggestion is quite helpful, I use it on my work, my images works correctly.
