HtmlGraphicImage and width/height parameters
Hi,
I need to pass "width" and "height" parameters
to a jsp graphicImage tag as following:
<h:graphicImage binding="#{cardLoader.image}"
url="#{facesContext.externalContext.requestContextPath}#{cardLoader.imageUrl}"
styleClass="card"/>
I use a binding component.
The bean called as this method:
private HtmlGraphicImage image;
public HtmlGraphicImage getImage() {
image.setHeight("10.0");
image.setWidth("10.0");
return image;
}
But I still obtain an error with setHeight and setWidth (a String
argument is required).
Where do I make the error ? 10.0 is pixel, cm, inches ?
May I pass directly the paramenters as shown here ? (I still haven't
tested this way)
<h:graphicImage width="#{cardLoader.imagew}"
height="#{cardLoader.imageh}"
url="#{facesContext.externalContext.requestContextPath}#{cardLoader.imageUrl}"
styleClass="card"/>
Thank you,
Nicola

you have plenty of options to do that using different stylesheet files
for each supported resolution
detect the client resolution in a Session scoped bean
detect the client resolution custom viewHandler
detect the client resolution in a filter chained before jsf rendering
first one is the easiest for me
this could be usefull also

My needs are to dimension an image, after having collected information
about the resolution of the client's monitor.
So I have to recalculate the width and height.
CSS are not involved in this case, IMHO.
