RE: [office] Draft for enhanced colors

["Francis Cave" <francis@franciscave.com>]

Hi Regina

Sorry, this is not my area of expertise, so I may well be asking naÃve questions!

I'm trying to see how this fits into the existing schema. All the elements in your proposal appear to be new. I appreciate that this is an early draft, but I see that you expect the enhanced colour model to be available in four contexts:

- <draw:gradient-stop>
- <style:fill-enhanced-color>
- <style:stroke-enhanced-color>
- <style:char-enhanced-color>.

Should <draw:gradient-stop> be <draw:gradient-step>? I ask, because there is an existing attribute draw:gradient-step-count, which might be related, and I don't understand that meaning of "stop" in this context.

What do you imagine would be the parent elements of the above four elements?

If fills, strokes and chars can have enhanced colors, are there other contexts in which enhanced colours could be used, such as extrusion, or the color of a material in the dr3d namespace?

I appreciate that an important purpose here is to increase interoperability with OOXML, but should we stop there or be looking for a more comprehensive enhancement?

Kind regards,

Francis

Hi Francis,

My intension was to have them all in namespace "style". That means <style:color-transform> element with style:transform-type and style:transform-value attributes, and <style:enhanced-color> element with style:color-type and style:color-value attributes.

  For example, on page 3 I get the impression that you were maybe undecided as to whether the attribute is style:color-value or draw:color-value. But I may be misinterpreting something.

That are simple editing leftovers I didn't notice.

But if you think all or some of those would better use "draw" namespace, that is OK for me.

With my other new elements it is the same problem. There will come <gradient-stop>, <char-complex-color>, <fill-complex-color> and <stroke-complex-color> elements which use the <style:color-transform> and <style:enhanced-color> elements as child elements.

It would be good to get some guidance in respect to namespaces.

Kind regards,
Regina
