Re: feedback from users: iscissors
Hello all, Please pardon my poor attention span... I think I must have missed some previous messages about "iscissors" since it is in the subject line but not in the message. Is there an archive where I can see what has been going on with iscissors? Thanks, L.

"Hollywood". I think they want to do that. Even if they don't, Hollywood is needed to store the colours (8 bit just isn't enough). -- -==- | ==-- _ | ---==---(_)__ __ __ Marc Lehmann +-- --==---/ / _ \/ // /\ \/ / [EMAIL PROTECTED] |e| -=/_/_//_/\_,_/ /_/\_\ XX11-RIPE --+ The choice of a GNU generation | |

having generic color-spaces and a way to access an image trought a
color-space and have it automagically converted would be awfull.
any project to include other color spaces rather that RGB in the GIMP?
ciao,

feedback from users: iscissors
I forgot: it seems that intelligent scissors work more or less nowadays. Kudos! I have some slight stuff to add. It seems that many selection functions using color comparisons to test limits of areas (iscissors, by color select...) use RGB space. Experience shows that human perception of area limits in an image don't quite follow the limits found by the program, I can perhaps conclude RGB space is inappropriate. As far as I remember, the eye distinguishes well the value, then the hue and saturation much less. Furthermore, the value is highly influenced by the lighting, so we might have to deal with significant differences because of shadows. A parametric comparison system in HSV space might be interesting. --- David Monniaux Tel: +33 1 44 32 21 15 Fax: +33 1 44 32 20 80 Laboratoire d'informatique de l'École Normale Supérieure, 45 rue d'Ulm - 75230 PARIS cedex 5 - FRANCE
