Subject Re: [Tobago] Image resizing
Date Thu, 21 Nov 2013 14:30:03 GMT
Hi Hani,

i think this is a performance issue but i found a solution:

<tc:column id="barChart" sortable="false" align="left">
  <tc:panel>
    <f:facet name ="layout">
      <tc:flowLayout />
    </f:facet>
    <tc:image value="#{item.gauge.resourcePath}"
                    width="#{item.gauge.width}"
                   height="16" />
  <tc:panel>
</tc:column>

this works in the demo.

Regards,
  Volker
