Looks OK to me...the only thing you don't mention is making the rough selection with the lasso tool. You might try toggling quickmask back on after the step 8 to see if you really have selected what you intend. That's the first thing that occurs to me is that somehow you aren't selecting what you want.


Two things strike me.
1. I didn't use the lasso tool - just applied the mask and used eraser tool. I intended to use
the lasso tool, but, for whatever reason - when I finish making my outline, and release the mouse button - the lasso disappears. Couldn't figure out how to fix that.
2. After I apply the "alpha to selection" - the outline lines disappear, and I basically am back to the original picture. Obviously, I must be missing a step somewhere, but haven't yet figured it out yet.

I'm reading everything I can find on the net, trying to better understand the basics, but still trying to figure out what the problem is here.
Thanks.

If you are doing alpha to seleciton and the lines disappear...there must not be any alpha...so either you don't have an alpha channel, or you haven't cut the piece away from it's background.

I think that's where the problem may lie. I was adding the alpha channel on the original pic, then doing the alpha to selection, before I copied.
I just did 3 different ones, where I waited until I finished with the quick mask, before adding the alpha channel, then copied, pasted as new - THEN, did the alpha to selection, invert, and cut.
That worked!

THANK YOU. I was determined to learn how to do this - you just saved some of what is left of my brain cells.. :)

yes, alpha to selection bascially means, pick any area of the image that isn't transparent and select it. If you have nothing transparent, then I am guessing it will either select nothing, or select everything.

Yup...take an image that doesn't have transparency and do alpha to selection, you will see marching ants around the edge of your picture...everything is being selected.

I was pretty comfortable with this procedure for a while, then today, I went to use it
for the first time in a while. For some reason, I've forgotten how to finish it after you
past your render into whatever picture you want. I get it pasted fine, but have forgotten
how to validate the paste.

Never mind - I stumbled into the answer. :)

I got all that to work...but when I tried to paste it into my image...it pastes the whole box with the cutout picture in it and i can't resize it without resizing the whole entire image, background and all.

I've gotten it to work before but now i'm stuck. >.<

You have to deactivate the mask view first (back to normal marching ant view of selection),
then copy and paste as usual

It is deactivated. There's no red background anymore...but the ants are around the whole picture box and the thing I cut out using the mask. It shouldn't look like that.
