making a surrounding area transparent: help a poor girl !

| I know this has been explained previously, but I just can't do it.
Our Squadron emblem has a light blue rectangle around it. I want to
make this light blue area transparent so I can overlay the emblem
partially on another emblem.
Can some kind person explain how this is done?
Thanks in advance

| Delete the Pixels you don't want
Save to an image format that supports transparency
(like GIF and PNG) by using the wizard-- it will walk you through the
process
File>Export> GIF or File>Export>PNG
Choose "EXISTING TRANSPARENCY"

Which part of what you were told can you not do?

Use the following (method 1) steps:
1. Open the squadron emblem image in PSP.
2. If this option is not greyed out, do Layers > Promote
Background Layer.
3. Choose the Lasso icon from the Tool Palette and then
select the Freehand option from the Tool Option. Trace
carefully around your emblem, letting go of the mouse
button to complete the selection. There will then be a
marching ants marquee around your emblem that does not
include the light blue background.
4. Do Selections > Invert. This causes the previously
unselected background to be selected.
5. Press the Delete key. This removes the selection
contents. Do Selections > Select None.
Method 2 is different, using erasing instead of selections:
1. Open the squadron emblem image in PSP.
2. If this option is not greyed out, do Layers > Promote
Background Layer.
3. Select the Background Eraser from the Tool Palette and
run it around your emblem. Keep the center of the brush
on the light blue background but have a portion of the
edge of the brush overlap your emblem. See this link for
more information about using the Background Eraser:
http://campratty.com/4tooltours/kz/bge1.html. Erase all
of your background.
Whichever method you followed, you now have your emblem on
a layer surrounded by transparency. Do Edit > Copy to put
this image in the clipboard. Now open the image you want to
overlay with this emblem and do Edit > Paste > Paste As New
Layer. This puts the emblem as a new layer over the image
you just opened. Use the Deform tool to move, size, rotate
or otherwise distort the emblem as needed.

Presumably the emblem is anti-aliased around the edge though, so simply
cutting it out will still leave a blue tint right at the very edges? I've
often wondered what can be done about that - is there a trick to getting
rid of it other than editing every affected pixel round the edge of the
selection one by one?
Do any of the retouch tools help - or is there even some magic procedure
that can attempt to do the reverse of the anti-aliasing process once the
selection has been marked out by looking at pixel colours either side of
the selection boundary? I doubt the latter would be anything like perfect,
but maybe it'd be good enough to be useful...
cheers,
Jules

The Background Eraser is made just for this.

It may or may not be. It would help if the original poster
gave specifics.

One technique is to contract the selection and then feather
it. See this link for how to do it:
http://pages.prodigy.net/kerrypierce/kyra.html
Another technique to be used when you have one pixel wide
authentic antialiasing (rather than feathering) at the edge
is to use Selections > Modify > Recover Antialias. This works
best if you select all of the uniform background, invert the
selection, select the Inside mode in the filter with output
on a new layer.

Yes, the magic is already built in. The Background Eraser
removes the background and subtracts its color from the
that of partly transparent pixels. Use the Sharpness control
to adjust the range of the effect. More info about this tool
is to be found here:
http://campratty.com/4tooltours/kz/bge1.html

It's amazing how close to perfect you can get if you use the
techniques skillfully.

open the pic in PSP...copy...open animation shop...paste as new
animation..click the paint can tool...click on the color
pallette..choose a color..doesn't matter..click ok..then up in the
tools click the box that says to canvas color..click the light blue
and it should all go clear...then click file..export frames to paint
shop pro..then again click file..break link to exported frames...go
back to psp and there's your image..sans light blue background.

Or... open the picture in PSP. Promote the background layer to a raster
layer, select the light blue with the magic wand tool, hit delete.
