Explain the tools in PageMaker toolbox.
1.
(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)
2.
Command Window
(i) The command window is normally located at the bottom of the application window, just above the statusbar.
(ii) This window normally contains three lines of text and the first two lines list the immediate command history,
(iii) The bottom line is the command line. If you do not see the command window, press Ctrl + 9 to make it appear.
(iv) You can enter a command manually at the command line.
(v) You can type at the cursor position on the command line, that is, the Command: prompt.
(vi) If you just type the first letter of a command, it will list all the commands starting with that letter.
(vii) Note: Always press ENTER after you type values on the command line.
(viii) You can drag this window to a different place on the screen and resize it.
(ix) When you enter a command, AutoCAD doesn't care if you use UPPERCASE or lowercase characters, or a combination of either.
(x) If you make a mistake typing on the command line, press the BACKSPACE key to correct.
(xi) You can press ESC at any time. If you press ESC while an operation is in progress, it terminates the command.
(xii) To repeat the command you previously entered in AutoCAD, press ENTER (or the spacebar) at the 'Command:' prompt.
(xiii) As an alternative, right-click to display the cursor menu, and then select the Repeat option.
3.
The Flash Tools panel includes the tools you need to create, select, or edit graphics on the Stage.
(i) 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.
(ii) By default, the toolbar is on the right side of your screen.
(iii) The single capital letter in parentheses indicates tile keyboard shortcuts to select those tools.
3D Rotation Tool (W)
It is used to create 3D effects by rotating movie clips in 3D space on the Stage.
3D Translation Tool (G)
It is used to create 3D effects by moving movie clips in 3D space on the Stage. The 3D Rotation and the 3D Translation tools are grouped within one icon on the Tools panel.
Lasso Tool (L)
It is used to select objects or parts of objects by drawing a freehand.
Pen Tool (P)
It is used to draw lines and curves by creating a series of dots, known as anchor points, that are automatically connected. Other tools used to add, delete, and convert the anchor points created by the Pen tool are grouped with the Pen tool.
Text Tool (T)
It is used to create and edit text.
Line Tool (N)
It is used to draw straight lines. You can draw vertical, horizontal, and 45° diagonal lines by pressing and holding Shift key while drawing the line.

Oval Tool (O)
It is used to draw oval shapes. Press and hold Shift key to draw a perfect circle.
Subselection Tool (A)
This tool is used to select, drag, and reshape an object. We know that vector graphics are composed of lines and curves (each of which is a segment) connected by anchor points. When you select art object with this tool, it displays the anchor points and allows you to use them to edit the object.
Free Transform Tool (Q)
It is used to rotate, scale, skew, and distort objects.
Gradient Transform Tool (F)
It is used to transform a gradient fill by adjusting the size, direction, or center of the fill. The Free and Gradient Transform tools are grouped within one icon on the Tools panel.
Primitive Rectangle and Oval (R)
It is used to draw objects with properties such as corner radius or inner radius, that can be changed using the Properties panel.
PolyStar Tool
It is used to draw polygons and stars. The Rectangle, Oval, Primitive, and PolyStar tools are grouped within one tool on the Tools panel.

JPEG (Joint Photographic Experts Group)
(i) JPEG was designed to attain maximum image compression.
(ii) It uses lossy compression technique, where a compression method is referred that loses some of the data required for the image reconstruction.
(iii) It works good with photographs, naturalistic artwork, and similar material but functions less on lettering, live drawings or simple cartoons.
TGA (Targa)
(i) It is the first popular format for high resolution images. TGA is supported by Most of the video-capture boards.
PNG (Portable Network Graphics)
(i) An extensible file format for the less loss, portable and well compressed storage of raster Images.
