RE: [xep-support] svg:filter

I've experimented extensively with this exact "problem". Even with the
latest version of RenderX there is little support for gradients and filters.

(Hopefully has become a development priority, as SVG is a fantastic means to
manipulate graphics from xml centric sources)

I have tried three sad work-arounds, each with it's own issues:

1. If at all possible script Photoshop to pre-prepare your images with
a shadow. (No doubt you've already considered this.)
2. It is possible to create separate graphics of your shadows and
"carefully" place these around your images using svg:image tags. It takes 5
separate images to do this if your original images vary in size, but you can
do it with 2 if you're dealing with uniformly sized images. (If your shadows
require a multiply of the underlying background this technique will not work
for you.)
3. I've had success with creating a top-left highlight/lower-right
lowlight bevel effect by overlaying 1pt lines over the outer-most edge of
images.

 I'd much prefer to use a shadow filter that incorporates a background
multiply but it is just not supported yet.

Good luck,

Dave Bickford

Subject: [xep-support] svg:filter

Dear support-team,

Can a basic filter be applied to an SVG image in RenderX?

I need to produce a shadow effect behind a picture. Is that at all possible?

This code should produce the right shadow but it does nothing:

<svg:filter id = "i1" width = "150%" height = "150%">
    <feOffset result = "offOut" in = "SourceAlpha" dx = "30" dy = "30"/>
    <feGaussianBlur result = "blurOut" in = "offOut" stdDeviation = "10"/>
    <feBlend in = "SourceGraphic" in2 = "blurOut" mode = "normal"/>
</svg:filter>

Any help would be greatly appreciated.

We're using version 3.8.1.

Kind regards,

Stijn Elst
