can I ungroup an imported jpeg?

Asked by Troels Ring on 2011-03-07

Just started using Inkscape but under some timepressure and therefore just experimenting. I have a not very complicated jpeg of kidney anatomy which I want to edit. So can I ungroup the parts of the jpeg or convert it into some form in which I can change the details?

JPEG is a raster image format and best manipulated in a raster graphics editor like e.g. GIMP. There is nothing to be 'ungrouped' if you just imported the bitmap image (aka raster image) into Inkscape: the information of the imported image is still pixel-based and not in vector format.

To edit such a drawing in Inkscape you need to "convert" the raster image into vector information first - either by automatically tracing it (menu 'Path > Trace bitmap…') or doing it manually (with the drawing tools from the toolbox to the left of the canvas).

For more information about using Inkscape's tracing function, see the included tutorial (menu 'Help > Tutorials > Inkscape: Tracing'), and read the manual for further details:
