Category:Valid SVG created with Inkscape:Stemmi

Wikimedia commons has countless examples for CoA shapes, in this category, and more of them spread everywhere.

There seems no need to create again and again more examples. These here belong to the worst ones, they consist of thousands of bytes of SVG code which is of no use at all;
they contain many drawings that are not shown: transformations, patterns and objects with a useles crazy accuracy of a millionth of a pixel, just to create an SVG code of large size.
Exactly the same images can be drawn with less than 1% of this Heraldicon code !

A much better example is e.g. CoA demoiselles 226x300.svg: , with a reasonable dimension (226×300) and an adequate license (PD-shape).
It is without any problem to scale it up or down, or to change its width/height-relation, and any fill-color and rim can be specified.

The other CoA shape examples of that user are not better, nor have they any educational value. Their creation seems to result merely from the fun of uploading.
They should never be used as templates for the creation of more large-sized but low quality coats of arms.
