Zooming Images
There are a number of different ways to zoom in and out, as described below.
The zoom level is always expressed in powers of 2. The available zoom factors are: 1:512 (1 screen pixel corresponds to 512 raster data pixels), 1:256, 1:128, 1:64, 1:32, 1:16, 1:8, 1:4, 1:2, 1:1, 2:1, and so on up to 32:1.
NOTE: When opening pages to preview, the page is initially shown as a low resolution continuous tone image. When zooming in, if you have the Raster Preview option, the continuous tone image is replaced with the high resolution raster data allowing for previewing traps, halftone dots, etc. Only the full version of Apogee will allow for high resolution raster data previewing. Other versions of Apogee can be upgraded to include the Raster Preview option.
To zoom the Preview window using the slider or menu option
1 In the Preview status bar, drag the zoom slider to the left to zoom out (up to 1/512), or to the right to zoom in (up to 32X).
To the left of the zoom slider, Raster Preview displays the current zoom factor. When zooming out, “1/” is displayed, followed by the zoom factor (1/2, 1/8, 1/128). When zooming in, the zoom factor is displayed, followed by a “X” (32X, 4X, 1X).
2 You can also select a zoom level from the View menu (View > Zoom In/Out). This zooms the image around the center of the preview pane. The View menu also includes the following options:
•Size to Fit. This selects a zoom level that fits the entire image in the Preview window.
•Actual Pixels. This sets the zoom level to 1(i.e. each raster pixel is represented by a single display pixel).

2 Click a point in the Preview window to zoom in on that point in the image.
Preview calculates an appropriate zoom factor to fit the active Preview window on your screen. Each time you click the Zoom tool, the zoom factor is doubled, until you reach the maximum zoom-in level (32:1).

2 Click-and-drag in the Preview window to select a rectangular area of your choice.

NOTE: Each successive zoom operation that you start will interrupt any ongoing operation. This means that if you start a new operation, such as a zoom in, before an ongoing operation is completed, then the ongoing operation will be aborted.
