1.            Answer all questions below, briefly but completely.

2.            Change the color of the answer to BLUE.

3.            Copy this information and paste in a new post in your DIGITAL GRAPHICS blog.

1.      Why are the GIMP Selection tools important? Because it makes thing much easier grab the item needed.

2.      What is meant by the “marching ants”? Black- and- white shimmering dashes the outline a selection.

3.      Describe the following terms found in the SELECT menu: ·         All select the whole image ·         None make sure nothing is selected ·         Invert reverses the selection ·         Float cuts out a selected area and pastes it as a new floating layer. ·         By Color switches to the Select by Color tool ·         From Path converts the current path to a selection. ·         Feather makes the edges of the selection fuzzy. ·         Sharpen makes a fuzzy selection sharper ·         Shrink and Grow make the selection larger and smaller ·         Border replaces a selection with a color or pattern using the Bucket Fill Tool to create an effect much like stroking the selection. ·         Rounded Rectangle rounds the edges of a rectangular selection. ·         To Path converts a selection to a path

4.      Why would you want to SELECT BY COLOR? So I can separate the foreground from the background.

5.      What is a BEZIER PATH? Let’s you define control points outlining your object. Then it connects the dots to create a path.

6.      What is the purpose of the INTELLIGENT SCISSORS? It tries to follow the boundaries of an object to make selection

7.      What is the purpose of the QUICK MASK? Let you see the selection visually superimposed on the image instead of the usual “ marching ants” view

8.      What is the purpose of LAYER MASKS? Defines how much, and which parts, of a layer will be visible.

9.      What is the purpose of SIOX? Simple Interactive Object Extraction is a foreground select to tool

10.  When is using SIOX most effective? When the image has significant color differences
