Save Colors from the Web with Instant Eyedropper

Friday, August 26th, 2011

1X1Instant Eyedropper is a free software program that allows you to easily copy and save any color you see on the Web. With Instant Eyedropper, you can identify and save the HTML color code so that you can use the color on your Web page or in an image editing program, such as Adobe PhotoShop. The best part is that you can do this with just one click and without opening any graphics editing software!

How it Works

Once you install the software, the Instant Eyedropper icon will appear in your system tray.

When you click on the icon, you will see your mouse arrow turn into cross-hairs. Continuing to hold the mouse button down, you can guide the cross-hairs across your screen; you will see a zoom of the pixels under the cross-hairs so that you can select the exact pixel you would like to identify and copy. You will also see the HTML code for that specific color.

Releasing the mouse button immediately pastes the information onto your clipboard.  Additionally, you can change what format the color code is saved as. For example, rather than HTML, you can save the information in Hex or RGB notation. Simply right click over the Instant Eyedropper icon in your system tray to choose from a list of formats.

Animations: Impact on Student Learning

Friday, March 4th, 2011

For this week’s Tech Tip, a professor of Biology at Loyola writes about academic 3-D animation software, Autodesk Maya, which comes with a free 3-year extended license:

We are all teaching students who have grown up with computers, the Internet, watching videos and playing computer animation games. Their brains have been trained, from a very early age, to learn new skills by watching these videos and animations.  It became very clear to me that my students grasp new concepts more quickly if they see a short movie or animation of that concept, rather than a still picture on a PowerPoint slide.   I have tried to find professional animations on the Internet and on textbook CD-ROMs. Publishers are now restricting access to these professional animations only to Faculty who adopt their textbook.  I would have to change my textbook each semester just to have access to these materials.  Even then, their collection of animations does not contain specific concepts I want to cover in many of my lectures, they are simply not available. I learned how to make animations using state-of-the-art software, Autodesk Maya.

Trimble’s SketchUp (formerly a part of Google) is free three-dimensional imaging software. It features simple tools that help you design 3D content. You can create shapes, buildings, machines or models.  SketchUp allows you to share your creations on its website’s gallery or export them into TIFF, JPEG and PNG files.
