circularArrow has bad guide formulas in presetShapeDefinitions.xml

Question

I have noticed that the guide formulas defined in presetShapeDefinitions.xml which is a part of ISO/IEC 29500-1:2008 electronic inserts, in OfficeOpenXML-DrawingMLGeometries.zip, do not seem to be quite right.  The head of the arrow never seems to be drawn correctly when following these formulas.  Is there a newer version of this document available somewhere, or perhaps someone has a suggestion to fix the formulas?

Answer 3

Hi Tom,

 

I actually believe I found the issue.  The guide formulas were defining a couple of names multiple times

 

<gd name="dxI" fmla="+- x2I 0 x1I" />
<gd name="dyI" fmla="+- y2I 0 y1I" />

...

<gd name="dxI" fmla="cat2 rw3 htI wtI" />
<gd name="dyI" fmla="sat2 rh3 htI wtI" />

 

I was able to fix the issue by changing the names of the second "dxI" and "dyI" and any following formulas that referenced them.

 

I am curious, though, if this is an error or if it is allowed by the specifications.  I wasn't able to tell for sure either way by reading through [5.1.11.11 gd (Shape Guide)] in "Office Open XML Part 4 - Markup Language Reference"

 

Thanks

Answer 5

Hi drmoore718,

 

We have determined that this is a bug in the presetShapeDefinitions.xml sample.  We will propose a defect report on this matter to Ecma TC45, for submission by TC45 to the maintenance group for IS 29500, and we anticipate that this correction will likely be approved and included in a future corrigendum for the standard.  Thank you for bringing this to our attention.

Answer 6

Hi Tom,

So you know, I recently found multiply defined guides in the following autoshape definitions as well

• gear6
• gear9
• leftCircularArrow
• ellipseRibbon
• ellipseRibbon2

 

Thanks for the info.

Answer 7

Thanks drmoore718!  Just to verify, these are the value names that I've found to be redefined:

•gear6 – a1

•gear9 – a1 and a2

•leftCircularArrow – dxI and dyI

•circularArrow – dxI and dyI

•ellipseRibbon – q1

•ellipseRibbon2 – q1

Did I miss any?

Answer 8

No, those are the names I found to be redefined as well.

Answer 9

Is correct version of circuitArrow xml exist? Thank you.

Answer 10

Hi Victor, the corrected version of the presetShapeDefinitions.xml file will be included in a future release of the ISO/IEC 29500 standard. For now, you can use the method described above to fix the definition manually.
