Making Transparent from Non-Transparent
Hi, Second big question is I have a lot of old logos Istored on a black background. Is there a way of turning the black transparent so that I can drop the logos on to a new background? I've looked in my small book but it doesn't cut. Another PS would be what are the best books? The Gimp Manual and Grokking The Gimp? Thanks, Jonathan "Hey, I think I finally got the hang of i-"

Under linux at least, there's a plugin named colortoalpha (i dont't know where in the menu exactly, i believe under Image/Colors, search in the PDB) that can be good for this. -Message d'origine- De: Jonathan Gift [mailto:[EMAIL PROTECTED]] Date: vendredi 12 janvier 2001 13:34 À: Gimp Objet: Making Transparent from Non-Transparent Hi, Second big question is I have a lot of old logos Istored on a black background.

But I can't grab the compiled deb binaries on the Debian site because they're compiled against sid and that means upgrading a lot of libraries on my potato system and breaking stuff. The other choice, I guess, is finding someone who has compiled it against potato, but I placed a post in Debian and no takers. last choice is compiling it myself... I don't know if it will work with potato's version of the GTK dev libraries and so further upgrading is in store.. Any suggestions welcome. I'd love to have it... BTW I do have a late 1.17 or somthing butw hen it loads it insists on nstalling, not in the customary .gimp directory, but .gimp-1.117 etc. directory. Clearly to show it's not done. ANY way to have it default to .gimp (I tried changing the paths in preferences and no go...). Thanks, Jonathan "Hey, I think I finally got the hang of i-"

Sometimes it needs some manual help, but it is a start. > I've looked in my small book but it doesn't cut. Another PS would be > what are the best books? The Gimp Manual and Grokking The Gimp? Yep, good books. GSR

I'd love to have it... Compile! Its not hard. Just download the source, unzip it, ./configure, make, su to root, and make install. It'll let you know during ./configure if you're missing stuff that you need. I always compile because I like to know that its built perfectly for my system. Debs and RPMS have made people lazy or something... For important things like the Gimp I compile. -- Jon Winters http://www.obscurasite.com/jon/ "Everybody Loves The GIMP!" http://www.gimp.org/

Don't have it, at least on 1.04 which came with potato and I'm trying to get my hand on something more recent... Have you an url for it? BTW, all the plugins I've seen come in source? You have to compile them all? Any special libraries involved? Thanks, Jonathan

If the background color is unique in the image, you can just do a Select > By Color and cut it. But you will need to do Layers > Add Alpha Layer first to add the transparency. Hope this helps, Teri Ward Tech Writer/Web Designer Seattle

Re: Making Transparent from Non-Transparent
Same problem with the upgrade thing running 1.17 also on potato have checked _extensively_ into upgrading but it is a definate no-go :/ Major breakage on a lot of things with the upgrade to woody. Ive decided to sit tight till some major problems with other proggies I run are fixed. About the changing to transparent I usually cut the logo out and paste it onto á tranparent bgbit of a hack ...and not for use with complicated logos lol but for a simple one it works well and sometimes you get some interesting effects :) anyway hope it helps Groetjes VosSedai "Cynics are made, not born." |"Great spirits have always found violent K.Marx | opposition from mediocre minds.

Ive decided to sit tight till > some major problems with other proggies I run are fixed. I'm about to go into that. You sure about the breaking. I've heard from one guy who has it up and running fine and as some great advice, but it looks like his system is a mixed Woody/Sid anyway. I just posted the list of what I think will be required. I'm just worried that it will break existing GTK apps, the libgtk upgrade... Jonathan
