you have to calibrate power of it, so it doesnt eat all grays, neither leaves too much whites :>

If you're working in Photoshop, then select your background with the magic wand tool and hit delete.  With that you have to make sure that your outer border of your lineart doesn't have any open spaces or your wand selection will go into your art.

I was just wondering why you want to do this.

Like the others said, the magic wand tool would work for that. (try unchecking "contiguous", that's useful if you what to select all the same color regardless of if it's in the same area of the pic.)

If you are doing this for coloring purposes, setting the layer to "Multiply" works better. Then you do the coloring on layers beneath.

i wanted to get the white off the backround of some lineart so i could make the backround on levels behind it, I didn't want to do the lineart in photoshop. It worked very well the way sheeta said to do it.

I posted the lineart and partially colored pic on the announcements forum, and I will post the finished picture when done.

You could also use color range, It's basicly the magic wand tool x10.

Still sounds to me like setting to lineart's layer to "multiply" would work easier. That will essentually make the whites act transparent. Or did you only want to get rid of part of the white?
 
If so, another option for doing that which I like to use is the layer mask. That lets you mask out part of the layer so it doesn't show. The biggest benefit is you are not actually deleting anything so it's easier to get the hiden part back if you made a mistake. You can "apply" the mask later to delete the hiden parts if you want. Layer masks also work well with adjustment layers (which is why adjustment layers are given a layer mask by default)

If you want, I can post more about how to use layer masks. They are actually quite useful.

The color range tool is a godsend.  It will select all the white at once, and then you can just clear it out.

Lesson: In Photoshop there is usually a wide variety of ways to accomplish the same thing.

Yeah, I work with the GIMP (open source Photoshop-level image editor), and I find that the Select by Color (Select->By Color) tool is great for these jobs. I think if you're editing a .gif to create a transparent section, it also helps to know that you're working with an image with a fixed set of 256 colors (or less), seen in the Colormap dialog (...though I don't currently remember any reason why that's useful).

Yeah, the continguous selection tool often works, but sometimes there are separate regions of the color you want to remove, and sometimes these are even forgotten and left in, as I have seen others and even myself occasionally do. Of course, if you have a background that's the same color as something in the image, you'll have to use it.

I wanted to just get rid of the white around her not he white in her.
