Color Pixels to transparent

turning a selected color transparent, is it possible?

[Jay_R]

I was just wondering if it was possible to turn all the pixels of a selected color transparent. I have a logo here that is partially transparent, but peppered with white pixels.

Is there an easy way to do this? How about the same effect over a certain selected area?

I have Photoshop 7, PSP 8, and MS paint... none of which I'm really good with yet...
Thanks for any help...

in PhotoShop you can set whatever color you want in the export of a jepg. you just have to assign a color as transparent. Another way is to copy it over to a transparent background and erase the white spots.

hope that helps let me know if i can help more.

You can also use find and replace - take the eye dropper tool - select the colour you want to replace and select transparent as the replacement colour. Then repeat for as many colours as you want. that's how it operates in Fireworks, and any thing it can do Pshop can do better....

Unforetunately Jpeg formats do not support transparency, in photoshop (I have photshop cs not sure if its the same), select save for web. And from there you can select which colors you want transparent.

Yeah, in Photoshop 7 you should be able to to "save for web" and in those screens you should choose .gif as the file format.
Turn on transparency.
Choose the color from the image using the eye dropper.
Now in the pallette, the color should be selected.
Now hit the tiny button under the pallette that looks like a grey/white checkerboard. This should add that color as a transparency.

The only problem is, PS only lets you select ONE color for transparency. Those white pixels may be the result of anti-aliasing.

Forgive me for rehashing an old topic, but I just wanted to say thanks for all the advice. I really appreciate it. I've been learning a lot. I actually downloaded PSP 8 and their little video tutorial was really helpful.

PSP seems a little less challenging to the beginner, just the PS help guide can seem overwhelming. I found myself clicking away and then forgetting what exit I took on the hyperlink highway…

PSP 8, for the price, just can’t be beat for the simpliees I need to do. However, it would be nice if I had a clue on graphic design and communication. I bet that topic has been hashed a few times, but I’d appreciate any help.
Thanks again all,
