Description Yousuf Philips (jay) (retired) 2016-07-30 06:24:27 UTC
Created attachment 126481 [details]

1) Open attached document created in Calligra Flow
2) Notice that in the layer tab bar the default Layout, Controls, Dimension Lines layer are shown rather than the actual ones - Layer 1, Layer 2, Layer 3.

The relevant xml code is

          <draw:layer draw:name="Layer 1" />
          <draw:layer draw:name="Layer 2" />
          <draw:layer draw:name="Layer 3" />


<draw:ellipse ... draw:layer="Layer 1" ... >
<draw:path ... draw:layer="Layer 2" ... >
<draw:path ... draw:layer="Layer 3" ... >

Yes, the import filter parses the multiple draw:layer into our default single draw:layer=Layout and loses the names of the source layers, as well as the draw:id

Probably not ideal handling for the import filter to be changing attributes.

And certainly disrupts things for interoperability on round trip for these ODF Drawings.

So i did some more digging and see that LO isnt importing the <draw:layer-set> because its a child element of <draw:page>, which according to the ODF spec is valid.


"The <draw:layer-set> element defines a set of layers. If placed inside a <style:master-page> or <draw:page> element it defines a set of layers for that page. If placed inside the <office:master-styles> element it defines a set of layers for all pages that do not have their own set of layers."

On Hackfest Hamburg, April 2018, we decided to solve this as part of a larger project to improve the handling and internal structure of layers. I guess the fix will need at least a half year to be done.
