SVG import "viewBox" attribute unexpected interaction with "width" and "height"

[Richard Mlynarik]

I am generating SVG files with very large viewBox min-x coordinates

eg <svg xmlns="http://www.w3.org/2000/svg" viewBox="36900 -60 7800 1590" width="7800" height="1590">

 

If I import such an SVG into Affinity Designer (1.9.3) the combination of the viewBox and width/height attributes causes the artwork to lie outside the 7800x1590 pixel document with large negative Y coordinates.

 

If I remove the "width" and "height" attributes (which specify the same size as those specified by the "viewBox" attribute) the file is imported in the way I expect.

 

Note that I don't know what the "correct" behaviour is -- just trying to reading the SVG specifications causes anger and confusion! -- but both Firefox and Safari web browsers don't seem to be upset by this combination of attributes, and it would be nice if Designer did the same thing.

Hi Richard,

Thank you very much for the files and the description - I've passed this on to development to look into.
