A client has supplied a logo for Web display (PNG). The logo
background is white and needs to become transparent. I've done this in
GIMP no problem with simple graphics. However this one features design
elements that cast a pale gray shadow onto the white background. Not
sure how to make the transparent background play nice with the shadow
If it helps, the background color where this logo will be displayed is
pale gray with a bit of blue tint.
Use the fuzzy select tool (magic wand) to select the background. Then go
to "select -> grow" and grow by 2 or 3 px to make sure all the
antialised edges are within the selection, but make sure that no white
part of the logo itself is selected. Now you can simply use "colours ->
Colour to alpha" (change the colour in the tools menu to white if
necessary) and it will perfectly extract the white from your background.
