When an alternate location is selected for the HTML Export that is outside the path of the Capella project, several icons end up with mismatching types.
Mismatches for icons referenced in the output\icon folder:
Sirius.png
DAnalysis.png
controlled_Actor.png
controlled_ConfigurationItem.png
controlled_Entity.png
controlled_LogicalActor.png
controlled_LogicalActorHuman.png
controlled_LogicalComponent.png
controlled_PhysicalActorNode.png
controlled_PhysicalComponent.png
controlled_PhysicalComponentBehavior.png
controlled_PhysicalComponentNode.png
controlled_SystemActor.png
controlled_SystemActorHuman.png
controlled_SystemComponent.png
When I replace all the above in the icon folder with *.gif versions, everything looks good. There may be more, but these are the ones I am using in the model to date.
With the following setting for the HTML output ( Preferences → Capella → Docgen XHTML → Status and Review – selected) The HTML code is looking for Project.png regardless of where the HTML export is stored (locally or alternatively outside the project).
Project.gif is in the xxxHTML\output\icon folder, but the HTML is looking for Project.png
