How do I set a drawing unit based on the size of an object in an imported PNG?

Asked by alfredo on 2017-08-11

I've imported a PNG into my drawing.

Say the length of a KNOWN object in that PNG is say 7.62 metres.

How do I get Inkscape to set up a scale in metres based on that object inside the PNG?

I want to be able then to measure the size of other objects in that picture.

You can use the realscale extension for this, see https://gitlab.com/su-v/inkscape-realscale-extension/tree/EffectCompat .

Can you help with this problem?
