transparency problem

[dead.rabit]

heyya. im using photoshop with another program. this program doesnt accept alpha values, instead you set a transparency colour
(and all pixels of the same colour are assumed to be transparent)

my problem is that photoshop tends to leave a pixel or 2 thick set of semi transparent pixels around whatever im drawing >.< these pixels in my second program are generally thaught of as being white, which screws up alot of projects.

i was just wondering, how could i solve my problem (im not a photoshop expert) but maybe theres a delete semi transparent pixels button (would be ideal) or can you turn off the way that it does this?

i appologise if this isnt explained too well
thanks anyway D.R =]

I'm not sure whether you had the same problem as I had a while back, but I found a solution to my problem in the following tutorial:

If every house in your city sparkles with lights and garlands,
if visible from all sides rosy cheeks of Santa Claus - means soon the New Year.
Preparation for this festival always takes one day and felt in the Christmas mood among the masses since the beginning of December. And if to the cherished date there are only a couple of weeks - it's time to think about a holiday in earnest.

hi,
a lot of times it helps a lot if you can provide a link to the image in questions... so many time there are different ways to do something depending on the image and give us a clear idea what the issue is...

sounds like your talking about halo's... they can be thin line around a object or just a few faded or simitransparent pixels along the edges..... i run into this all the time my self and there different ways to handle that...

note: a lot of the time the problem is because of alogrythms or the compression of a image... especially a jpg.... anyway here a few tutorials tha might help , some case very similar to that article that brucula gave you ...

i haven't found a single procedure that will work in all cases... sometime i will fill in the transparent with a similar color before i take over to my animated gif creator... or sometimes i'll just make a good selection and delete the halo's, sometimes i'll even use the dodge and burn tool....lol ..
