Removing Background from Image
« on: April 11, 2011, 04:40:25 pm »
I have a request guys, attached is an image I'd like the white part to be removed so that it is nothing (transparent) and it has no background so it will go fine in any colour.

Thanks, if you could also tell me how to do that :D

I tried a rubber in Paint.NET but it's hard to control it, even with anti-aliasing enabled.

There :)

I used the GIMP to do that.

1. Right click on the layer in the layers box and add an alpha channel
2. With Ctrl+magic wand, you select the white parts
3. Delete button on the keyboard.

The job is done in no time.

Gimp is your friend!
I think its just something like Layer -> Transparency -> Color to alpha .

That works too. In fact there's multiple ways to get the job done.

Optimized. ;D



Sorry, I just had to. It's a pretty epic optimization, though.

What did you do, reduce the color pallet? That would make the most sense to me. :P

On an off-topic note, do we still need to uninstall TiEmu to use GIMP and vice-versa? That was why I always stayed away from GIMP before, aside from the fact I disliked how everything were separate windows (I prefer everything in one window like Paint Shop Pro and Photofiltre Studio).

Thanks guys! If I had Photoshop I could do this, but I uninstalled it.

No idea, sorry.

I have both gimp and TiEmu on my computer, so this isn't normal behavior. Both gimp and TiEmu use the gtk-toolkit (gtk was actually made for gimp). Maybe its because one of the programs was outdated, and used an older version of gtk. I think having the latest version of both should work (gimp and TiEmu).

The next version of gimp will be able to support single windows, but probably will have to wait still a while before its released, as they have a lack of developers.

Scout, since you are on Linux, it will be quite easy to get the development version of gimp (I don't think its that unstable).

I see. It's probably because back in the days both used different GTK libs (or related stuff) so they conflicted. I haven't tried since 2005 or so, though.

And thanks for the info. I guess I'll have to check out at one point in case they get devs.
