Removing Background From Picture 2

There are several methods to extracting (removing an object from it's background).


Simple Background, but not solid color - Background Eraser

  1. Open your image
  2. Hold down Alt and double click the background layer
  3. Select the Background Eraser Tool (under the Eraser Tool (E))
  4. In the option Toolbar (top of your screen under File/Edit/Image...) change the brush size to about 150
  5. Click around the edge of your image with circle slightly inside the edge What's happening is that wherever the cross in the middle of the circle is, well that's what color you're erasing. If it's erasing too much (part of the image too), then change the "tolerance" lower. If it's not erasing enough, then change the "tolerance" to a higher number.
  6. Select the Eraser Tool and erase everything else

You now have extracted your image!

Dreamweaver MX Links

Question: If I delete a page out of a site, can I tell how many pages were linked to it and how do I change the previous link to a non-link?

Answer: When you delete a file from a site, a message pops up telling you which files are linked to it. I'd update the site cache before deletion. To clear any other problems, you can use the Results panel to find broken links and orphaned files.

Creating Rounded Edge in Photoshop...

Question: I would like to create a curved edge on right bottom side of a rectangular image. The image needs to be stroked on the bottom and right side including the curve, by 1 pixels black color.

My curve is not turning out to be smooth...

Answer: Try using the Elliptical Marquee tool (M) as an eraser/brush mask over your rectangle then invert the selection and erase or brush as needed. Don't forget to feather. (You can constrain the elliptical marquee tool to a circle and draw from the center using the "Shift plus Alt" keys.)

ColdFusion User Roles

Question: I am using DreamWeaver MX to create a coldfusion member area. I am having a problem restricting access to my member area. I am able to login in with different usernames and the correct information is displayed according to the username. Is there a way to restict access based on username and password?

Answer: Yes, assign user roles to the users and only allow users with a certain role to access the page.
