[Qgis-user] Is location info included in metadata when save an image file?

[Ert Four]

Thank you, I didn't know SVG was XML/text based, I will check that out.

Sometimes I will need to export a PNG or JPG. Sorry, I need to be really careful, have you or has anyone reading this read the relevant parts of the code, by chance?

For now I'm taking screenshots to be sure nothing is transmitted, but that has limitations.

Thanks.

Then I zoom in on a group of points from my data layer, I turn off the basemap layer, and make a map with just my data points. I want to preserve the relative spatial relationships between my points but not reveal where in the world the map came from. If I publish this image file, might the metadata reveal the location?
