I would like to craeate my own EGO with sprites which i have made. Bud if I create an sprite in Photoshop and save it as .TGA with transparent background, there is an awfull WHITE line around my body.
If i put my EGO on black background, there is some BLACK line around. How can i do a realistic sprite of a body?
Thanks to all
AGS cannot normally handle semi-transparent bits in sprites, so you'll need to make hard edges for the sprites...
Thus my ignorance about the 32-bit possibilities, I cannot say if you can do it with alpha channel thingys, because I don't know what this alpha channel thing is... but someone knows, and will tell you (and me)...
This is usually due to programs like Photoshop anti-aliasing the image before saving it, and thus leaving a border when the background is made transparent.
Disabling anti-aliasing in photoshop should fix it -- I'm not sure where the option is, but I'm sure someone else can help if you can't find it.
Yes good Idea...I heard about anti-aliasing in background manuals...I'll look for it. Thanks
When you design your sprites in Photoshop, you need to keep in account that the alpha channel in what will make your sprites anti-aliased. Just make sure that when you design your sprite that the colors spill over the alpha channel, so it picks up the colors from your sprite to anti-alias instead of picking up the background color of your layers (i.e. why you get a black/white ring).

Here's a Zipped Targa file to load into Photoshop, so you can get a better idea. Just look at the alpha channel (The tab named "Channel", next to your layers tab) to see that the anti-aliased area is actually smaller than the sprite area.

Hope this makes since.
Erm: maybe I am stupid
I tried your zipped file and looked to channels..I didn't find any Alpha Channel so I tried to do It.
But if i put an Alpha channel on this Example.tga it become fully BLACK! I tried to change settings of this channel by double clicking, but no changes:(
What version of Photoshop do you have?
Adobe Photoshop 7
This is where your alpha channel is.

I created an alpha channel but it is already BLACK! http://juste-milieu.czweb.org/ALPHA.jpg
I looked to a manual of Photoshop and they write here, that i can create this alpha with black and white drawing...So i did it but now I dont know what next:( I tried ctrl+J but its still ugly
Thanks
Sometimes what appears to be black is slightly not-black (like RGB 0,1,0) because of various operations and anti-aliasing... You can maybe try using the magic wand with a tolerance = 0 to grab all the black background; if you see there is some next to the sprite that is not selected, then it is not quite black there.
