Ever frustated using Inkscape when you snap together between two objects? Or when you design tiled pattern or background, some white lines appear that make you stressful. There are white lines between them if you zoom in or export it as image file. This happens not only in inkscape, also in other software like Adobe Illustrator and Corel Draw.

Note: filters folder i created manually.
and then restart Inkscape to have the new personal filter loaded.
You can access the new filter from the inkscape menu: Filters > ABCs > Stitch together, applied that filter to selected object.
