linearGradient not exported correctly if id begins with number

[epuig-ssinergie]

When saving SvgDocument to PNG, the gradient area is rendered as solid black.

After several tests, it seems to be directly related to the linearGradient which is beginning with a number, eg:
<linearGradient id="41cb5de8-82e7-4ab5-94d7-87e10775c848"

As a workaround i'm just adding a letter at the beginning of id and it works perfectly.

Thanks

same issue with radialGradient elements

According to W3C, an id name cannot start with a number, so this is not a valid SVG - not supporting this is not a bug.
Is there any standard application that generates this kind of ids? In this case, it may make sense to support this nonetheless.

svg was generated using ASP.net Telerik library with getSVGString()

Ok, thanks - while this is basically a bug in the converter, it would make sense to handle this in that case.
