PDF Font Colour (Color for some...)

[damianharvey]

I am creating a PDF using the Seam iText PDF Generation components and trying to set the colour of a table cell via the p:font tag. As I see it the 'color' attribute is missing from the Seam code but is present in com.Iowagie.text.Font.

Is there another way to set the colour or does org.jboss.seam.pdf.ui.UIFont need a bit of code like below?

color = (Color) valueBinding(context, "color", color);
if (color != null) {
 font.setColor(color);
}

I tried changing the code but ran into an error "Component property color is not writable" at which point I had to move on.

Cheers,

Damian.

Looks to me like this needs a feature request in JIRA

I've added a color option to UIFont. Let me know if you have any problems with it.

Thanks for that. The good news is that colors now work. The bad news is that <p:image> is broken. It gives a NPE.

Replacing the jboss-seam-pdf.jar with the one from 1.2.1 lets image work again, but of course not color.

p:image has changed for 1.3. It would now uses the value attribute for all types of values:

<p:image alignment="right" wrap="true" value="/jboss.jpg" />
<p:image alignment="center" value="#{images.chart}" />

It also accepts seam image transforms::

<p:image alignment="center" value="#{images.chart}">
<s:transformImageBlur radius="3" />
</p:image>

If I try to use the value attribute on what was a resource it throws an error:

java.lang.IllegalArgumentException: Cannot convert /img/myimage.jpg of type class java.lang.String to class java.awt.Image

Looking at the UIImage code I can't see how it could ever take a path to an image. Or am I missing something?

Thanks,

Damian.

The above code fragments are from the itext example. You'll need to provide more details.
