In Inkscape I have drawn a square and then applied Drop Shadow filter to it.
How could I please get rid of the appeared top and left space?
I need to have the top-left corner of the yellow square at the point 0, 0 – so that I could resize the document size to just the square and the shadow (then I would export it as bitmap(s) and use in my app).
In Gimp I would just apply Image – Autocrop, but how to do it in Inkscape?
After applying the drop shadow to the rectangle, go to filter general settings in the filter editor dialog. Change the values for co-ordinates x & y which displaces the top left origin point of the rectangle. Similarly adjust the dimensions correspondingly to retain the same width & height for the shadow.
The values specified in the image is the default value. You may need to vary those values to get the required origin point for selection.
