I am a senior professional and work as a fine art illustrator, mostly rasters on gimp. I do use Inkscape alongside. since a couple of years i am working on patient education in hindi booklets 7 have more than 50 titles booklets to be published, 10 pages of 3x11" each. Illustrations, diagrams with devnagari text. My laptop lost its display and crashed with Ubuntu 19 and while converting os I found my svg files are mere png's and uneditable. Anyone have experienced similar problem or an explanation/help, please respond. Years of hard work is unreachable. Help recover it. Thanks.
