hi guys,

i couldn't figure out where was the best place to post this topic. so basically, i want to convert an image to its negative. i tried picasa3 but it doesn't provide that option, only to bw, sepia and others, but not to negative.

i'd appreciate a lot if any of you can shed some light over this

many thanks.

hi clare,
long time no see. how's london treating you?
yeah, i guess photoshop does the job. but i haven't got a copy either in my lab or personal computer, i'm testing cellprofiler at the moment, i think this program can transform the image, and it's free.
cheers.

you can try graphic converter, from lemkesoft, for the mac. the "invert" command should do it.

Hi

Cambridge is treating me like a $%£&*^$£"^&£* so I am off on a hunt for a new job (perhaps Edinburgh, but who knows!).

oh yes, of course you're in Cambridge... sorry about that. it was Kami who is in london. at least there are three £ signs in the way they're treating you

Edinburgh sounds nice, haven't been there yet tho.

mdfenko, thanks. i'll try it in the mac that is available upstairs (a different lab).

good luck to you both!

Gimp will do the job too, if you use the portable version, no installation is necessary....

Hi toejam,
If I understand your problem correctly, I got a solution for you.
I got a "guarantee works" and "free from any software installation" method if you are using windows 95, 98, XP, Vista, ...etc...

1) Open Paint (Start>All Programs> Accessories> Paint)
2) Open the picture you want
3) Choose "Image>Invert Colours" from the tool bar

Done.

Adrian

Expecting the world to treat you fairly because you are a good person is like expecting the lion not to attack you because you are a vegetarian.

hi guys,

thanks for all your suggestions. the gimp did the job. it was something really simple. actually, openoffice 3.1 (that's the version i'm using) can invert the colour of the images in its word processor.

all the best for you!
