You just need to make your original in a higher res with more detail. Once you have masked the BG, THEN cut it down to size and export with transparency.

You are masking the background when you choose transparent. The issue is that the program is only removing certain colored pixels, and at the edges of your image, there are pixels that are cross-colored. They are there to blend the image into the existing background. So when you mask the bg color, you are only masking the pure white (or whatever color) pixels out. The remaining edges are bleed colors from the image.

and the program you are using is ....

Hi guys

I guess if we get our basics right it's just a matter of choice.

If you want smooth edges then you will have to sit back with the white (or rather a gradient) edge coz the least amount of space a color can occupy is one pixel.

If you want to avoid that white noise as you call it, use the difringe command in Photoshop. That helps you get rid of most of that white noise. You will have to get rid of the rest with one pixel eraser. But beware the result would have jagged edges.

Do let me know if anyone has a better piece of info.

Exactly. This is why I suggested making it a high res image BEFORE any editing. Make that sucker 300 DPI, THEN removed the white around the edges. You will find that the removal leaves a MUCH smoother finish as opposed to leaving it at 72DPI. Once done, then make your size adjustments as needed.

If you want to use your transparent image in some software like MS Word which doesn't give a damn to what resolution your image is you can do what PC-Grafix said. Create a high res image, then delete the background and export with the help of the wizard in Help menu. That would do the trick.

If however you want to use it in some other graphics program or some other file in photoshop itself there are better ways to do that.

I tried creating one and included it on a webpage over text. Below are the results. If they are satisfactory for your purpose, lemme know and I will tell you how to exactly get such results.

This is the image:

Hence, the instruction to "make your size adjustments as needed" Why is that so hard to understand? - size = res when working with web image. I do such work all the time. It really isn't a big deal. Sorry I seem to have stepped on your sensitive toes. Knock yourself out pal, I'll stay away from now on.

What (and who) are you getting so pumped up at, pal?

I appreciate your concern and that you have loads of practical experience but you definitely can't use a 300 dpi image for web. Scaling an image doesn't reduce its filesize, interpolating does. You have to interpolate an image to 72 dpi if you are going to use it on web. Isn't it so?

If it is for print, as i said, for MS Word or something like that, you can use a 300 dpi image and scale it down (thus scaling the noise down too) to fit the available space coz then what matters is the printed output and not the filesize on disk.

If I sounded dumb or offending, accept my apologies.

Well lets see. I don't know what kind of monitor YOU have, but mine has resolution settings. I currently have them both set at 1200x1600 which mean the screen print 1200 pixels down and 1600 pixels across. Now, regardless of the size in inches when the image prints, which is all DPI does, how does making my image 300 DPI effect how it display on a screen? Lets say I have two images, one is 200x100 at 72DPI and the other is 200x100 at 600 DPI. How much screen space do each take up? THE SAME! What is the difference? Yeah, some bandwidth. Which leads to your issue with my explaination. What is your problem with this? Are you too blind to REPEATEDLY see the instruction to ADJUST the image once the editing is finished? I prepared three images to prove my point. An original JPG, and two GIF. You know what. screw you. I am not goign to waste the bandwidth on my server to prove my point. You just keep doing things your myopic way and making sure no one else can have other methods.

Your advise left the user with jagged edges, my advise corrects that problem and results in EXACTLY the same file size. Yet you start using a tone that indicates I don't know what I am talking about, THEN wonder why I am "pumped up". Well you're the reason. You apparently have little practical experence and are not open to other ways to do things. And you know what? That fine. I am outa here. You amatures can have this forum. It's full if kids with nothing to do and people like you. Post as many replys as you like. I wont be back to read them.

Goodbye.
