Andreas L. Delmelle commented on FOP-2549:
------------------------------------------


I think so, especially in this case, given that it is the final stop _and_ has 
the exact same color. 
Reading the SVG spec on gradients, there is an example mentioned with two stops 
having the same offset, but it is not the last one and it has a different 
color, so in that case, the result would be wrong if we just skip it entirely. 
I have not yet tried how FOP currently processes that sample, though...

> A radial gradiant isn't processed correctly by FOP. E.g. the following 
> gradiant:
> <radialGradient
>    cx="51159.898"
>    cy="57300"
>    r="5279.6602"
>    fx="51159.898"
>    fy="57300"
>    id="id0"
>    gradientUnits="userSpaceOnUse">
>    <stop
>    id="stop28"
>    style="stop-color:#fefefe;stop-opacity:1"
>    offset="0" />
>    <stop
>    id="stop30"
>    style="stop-color:#cdcece;stop-opacity:1"
>    offset="0.58823502" />
>    <stop
>    id="stop32"
>    style="stop-color:#9d9e9e;stop-opacity:1"
>    offset="1" />
>    <stop
>    id="stop34"
>    style="stop-color:#9d9e9e;stop-opacity:1"
>    offset="1" />
>   </radialGradient>
> is only outputted with one "Bound" entry in the PDF color function (instead 
> of two).
> When opening the PDF with Adobe Acrobat the SVG is only partially displayed 
> and an error message pops up after clicking on the image.
