Topic awaiting preservation: transparency (Page 1 of 1)

Is there any easy way of cleanly removing white backround from an already saved picture such as this (just a random pic)

what programs you have access to?

and, do you want it over a different background for an image, or transparent for web?

adobe photoshop/imageready 7.0.
for a clean web pic as well as a backround to a sig

Copy the image onto a transparent layer, go to select > by color... [make tolerance higher to get the half way pixels] put the eye dropper on white, click, then delete.

So you do have Photoshop then? I don''t think it comes separatly?
A quick way would be to open it in PS, convert it to RGB (Image>Mode>RGB). Then duplicate the layer, go to (Select>Colour range) then click on the white part of the image, click OK. Delete the resulting selection. Then if you want to see how it looks against this kind of background, make a new layer, fill it with the colour (#2B0404) and drag it below the image layer.
If you like what you see and want to save it as a transparent .gif for display here you do this.
In the layers pallet only have the one layer that you deleted the background from visible, all the rest turn off. Go to (File>Save for the Web). Choose Gif in the Settings, click the matte setting and set it to (#2B0404).
Click the preview button for one last check, and save.
This is very rough as I don't know your level in PS.

you could copy and paste it into a new channels layer, adjust levels, and you got a nice mask.....

or

If you just want it over a different background, go to layers, and select the darken, or multiply blend mode. This will nock out the lighter colors...

the multiply will probably make the green look black though...

perfect, thanks once more.

Select -> Color Range
