Image not transparent in generated pdf

[neian]

Hello,

I have a problem in the image embedded in the pdf file that jasper report generated. The image was not transparent and has a dark grey color.

This occurred when I used PJA toolkit to be able to run the JasperFillManager.fillReport(xx) in our unix server.

I am using the code below to get the image.

Image logo = new ImageIcon(imageURL).getImage();

 

In the jrxml, the image is declared as an Image object.

<image scaleImage="RetainShape" isLazy="true" evaluationTime="Now" hyperlinkType="None" hyperlinkTarget="Self" >

<reportElement mode="Transparent" x="191" y="30" width="167" height="62" key="image-1"/>

<box topBorder="None" topBorderColor="#000000" leftBorder="None" leftBorderColor="#000000" rightBorder="None" rightBorderColor="#000000" bottomBorder="None" bottomBorderColor="#000000"/> <graphicElement stretchType="NoStretch" pen="None"/> <imageExpression class="java.awt.Image"><![CDATA[$P{Logo}]]></imageExpression>

</image>

Maybe somebody has also encountered this and can share their insights on what could be the cause of the image problem and how to solve it?

Thanks.

Hi,

 

Are you sure you need PJA? I mean, have you tried the -Djava.awt.headless=true?

 

I hope this helps.

Hello,

Thank you for the suggestion but I cannot set the java.awt.headless = true since I am using jdk 1.3.

However I was able to find a solution for my problem. I just need to put my Image in a BufferedImage and use the Graphics2D to draw the Image.

In order to use jasper reports in the Unix environment, we used PJA toolkit and just set the server properties as per PJA documentation.

Below is the code I used to generate the Image.

 

public static Image getLogo() {

 

URL imageURL = Thread.currentThread().getContextClassLoader().getResource("images/WMS_K_2.jpg");

ImageIcon icon = new ImageIcon(imageURL);

BufferedImage logo = new BufferedImage(icon.getIconWidth(),icon.getIconHeight(),BufferedImage.TYPE_INT_RGB);

Graphics2D graphics = logo.createGraphics();

graphics.drawImage(icon.getImage(),0,0,icon.getImageObserver());

 

return logo;

}

Hi,

 

Is this a solution recommended by PJA or is something you found by trial and error?

 

Thanks,

Hello,

To be able to display the image in a pdf, I found the solution in the PJA Toolkit forum.

 

Thanks.
