Hi Teodord,

 

I mean the image is getting displayed but instead of the logo it is displaying a strange image (it is displaying some square sought of image with red,green and blue colors inside it).And even the font is coming as bold if it is dynamically generated in browser.But it is displaying the logo correctly in HTML format and even in a PDF report that is being saved on a disk .But I'm getting this image problem only when i want to dynamically generate the PDF report on the browser.The image which i want to display is a GIF image.Can u plzz analyize whtz the problem....

Thanks,

dolly

hi,

 

Below is my <image> element code from jrxml file:

 

<image scaleImage="Clip" onErrorType="Icon" isLazy="true">

<reportElement x="0" y="0" width="40" height="50"/>

<graphicElement stretchType="NoStretch" pen="None" fill="Solid" />

<imageExpression class="java.lang.String">$P{ImagePath}</imageExpression>

</image>

 

As u suggested i have used onErrorType="Error" but it did'nt work.....

 

Thanks,

dolly

Hi,

 

The image path you pass as parameter is an URL?

Anyway, I asked you to use onErrorType="Error" so that the engine throws an exception if the image could not be loaded during PDF export. Make sure you recompile the report after you modify the JRXML template. And also, make sure you are not catching exceptions and then silently ignore them when you export to PDF.

If there is a problem with the image, then the exception should be somewhere.

 

I hope this helps.

Hi,

 

So as you said on the other thread, you do get an exception telling you that the image was not found at the time of the PDF export.

Since the image has isLazy="true", it means the engine will not make any attempt to load the image at report fill time, but it would be the responsibility of the exporter to deal with the image.

The HTML exporter does not do anything with lazy images. It just puts the URL exactly like it received it, so the browser will load the image from the indicated location, which is most likely a public URL. If you see the image in HTML, it means the browser had access to that URL and was able to load the image.

The PDF exporter, when faced with a lazy loaded image, would try to load the image data from the specified location and embed it into the PDF output. But what if the server that executes your application does not have access to that public URL? Is that the case with your deployment? If your logo is on a public website, does your PDF generating machine has access to that public website?

 

I hope this helps.
