Interactive Image Position Control

Users can move the viewing position interactively using the Video window,

Map View window, and the List View dialog box.

The Video window provides the fine position control. There are three basic

techniques:

1. Point-And-Shoot

Double-clicking anywhere on the video window moves the image to that

position. For example, if the device IC1 can be seen in the lower left corner of

the screen, then to move to IC1, use the mouse to point to IC1 and double-

click the left mouse button. The image should move so that IC1 is at the

centre of the screen after movement is completed.

2. Incremental Move

There are eight triangles overlaid on the perimeter of the video window. Each

triangle is an incremental move button: to move one field of view in the

selected direction, place the cursor on the appropriate triangle and click the

left mouse key.

3. Panning

Panning moves the image slowly and continuously in a straight line. Its best

use is for fine positioning. There is a dotted line rectangle on the perimeter of

the video window which marks the action zone for panning. To initiate

panning, place the cursor inside the dotted rectangle near one of the dotted

lines, depress and hold down the left mouse button, move the mouse pointer

slowly towards the outside of the rectangle. The image will start to move once

the mouse pointer is outside the dotted rectangle. The farther away the

mouse pointer is from the rectangle, the faster the image will move. By

moving the mouse toward and away from the dotted rectangle you can control

the speed of the motion. Releasing the mouse button stops the motion.

The Map View window provides a global view of the entire PCB. The window

is divided into squares, with each square representing one image view. The

Map View also provides coarse image positioning. For example, double-

clicking on a square anywhere in the window moves the image to the

corresponding position on the board. Double-clicking on the top right corner

of the map view moves the image to the top right corner of the board.

The Device List View provides device-oriented image positioning. The device

list View dialog lists all the devices’ reference IDs (i.e., R12, IC34, etc.) in

alphabetical order. The user can scroll the list to find a device. After a device

is found in the list, the user can conveniently move the image to view the

device simply by double-clicking on the device’s reference ID in the list.
