The Flash CS6 workspace includes a variety of tools and other components that you work with to create Flash applications.
Flash Window Components
The Flash window is divided into four main components. They are
1. Stage and Pasteboard
2. Timeline
3. Tools panel
4. Property Inspector
1. Stage and Pasteboard:
(i) The white rectangle area in the middle of your workspace is called the Stage.
(ii) All the animations, objects and scenes for a Flash movie are created, edited, placed and played back in the stage.
(iii) The gray area surrounding the Stage in Flash is the Pasteboard.
2. Timeline
(i) The time line is one of the most important components of Flash.
(ii) It is located below the Stage. It is used to specify of each element's appearance and animation.
(iii) The Timeline also contains Frames and Layers.
(iv) Flash movies measure time in frames. Frames are the discrete, small slices of time.
3. Tools panel
(i) The Flash Tools panel includes the tools you need to create, select, or edit graphics on the Stage.
(ii) The double arrows at the top of the Tools panel are used to collapse the panel to icon only view, or to expand the panel and see all the tools.
4. Property Inspector
(i) The Property Inspector appears on the right side of your Flash workspace by default.
(ii) It is grouped with the Library panel.
(iii) It displays properties and options for objects selected on the Stage, and also allows you to modify them.
(iv) The object can be text, an image, a line, or any other shape.
The AutoCAD 2016 interface is based on Ribbons and the Application Menu,
The important feature of this interface is that the size of the Graphical Area will be bigger.
(i) One of the most basic shapes used by drafters and designers is the rectangle. You can create a rectangle using the LINE command, but doing so has some disadvantages.
(ii) For example, you would have to take the time to make sure that the corner angles are exactly 90°. Also, each line segment would be a separate object.
(iii) Therefore, AutoCAD 2016 provides the RECTANG command, which allows you to create a rectangle with perfect corners and as a single object.
(iv) Clicking anywhere on a rectangle created with the RECTANG command selects the entire rectangle.
To draw a Rectangle using the cursor to select the corners:
1. Command: RECTANGLE (or) REC (Press Enter Key)
2. The following will appear on the command line:
RECTANGLE
Specify first corner point or [Chamfer/Elevation/Fillet/Thickness/Width]:
Specify the location of the first corner by moving the cursor to a location (P1) and then press the left mouse button.
3. The following will appear on the command line:
Specify other corner point or [Area/Dimensions/Rotation]:
Specify the location of the diagonal corner (P2) by moving the cursor diagonally away from the first corner (P1) and pressing the left mouse button. Now a rectangle will appear.
Draw a rectangle defined by diagonal points (20,30) and (150,160).
Command: RECTANGLE ⤶
Specify first corner point or [Chamfer/Elevation/Fillet/Thickness/Width]: 20,30 ⤶
Specify other corner point or [Area/Dimensions/Rotation]: 150,160 ⤶
A Rectangle define by diagonal points (20.30) and (150,160)
After created text in a text block, if you want to convert it to a frame. You can do this by using these steps.
(i) Draw the frame of your choice using one of the PageMaker's Frame tool.
(ii) Select the text block you want to insert in the frame.
(iii) Click the frame while pressing the Shift key. Now both elements will be selected.
(iv) Choose Element > Frame > Attach Content on the Menu bar.
(v) Now the text appears in the frame.
(i) The main purpose of PageMaker is composing pages. You can insert new pages into a document, remove existing pages, move between pages, and sort pages in a large document.
Going to a specific Page:
PageMaker provides several methods for navigating the pages in your publication.
Method 1:
(i) You can move from one page to another by using the Page up and Page down keys on your keyboard.
(ii) This is probably the navigation methods you will use most often.
Method 2:

Here are some general guidelines for taking good portraits:
(i) Use longer focal lengths instead of shorter (telephoto instead of wide angle). This will make your subjects face more natural and less bulbous.
(ii) Use a wide aperture for shallow depth of field. This will focus attention on your subject and not your background.
(iii) Avoid distracting backgrounds.
(iv) Try to achieve even illumination by exploiting natural light. If you can't use natural light, then use studio lights and/or multiple flashes and/or a bounce flash.
(v) Avoid taking pictures where part of your subject's face is in shadow unless you really know what you're doing.
(vi) Avoid using a single flash pointing directly at the subject. This will create harsh shadows on either the subject of the area behind the subject.
