USING PHOTOSHOP CS4

3D and technical imaging

Last updated 1/10/2010

After creating frames in the (Animation) Timeline panel, you can save DICOM files as QuickTime movies (change

grayscale DICOM files to RGB, and then render to video). You can also save frames as animated GIF files (choose

File

> Save for Web and Devices).

You can also use the Timeline panel to animate a 3D volume created from a DICOM file. See “Create 3D animations

(Photoshop Extended)” on page 598.

Measurement (Photoshop Extended)

About measurement (Photoshop Extended)

Using the Photoshop Extended Measurement feature you can measure any area defined with the Ruler tool or with a

selection tool, including irregular areas selected with the Lasso, Quick Select, or Magic Wand tools. You can also

compute the height, width, area, and perimeter, or track measurements of one image or multiple images. Measurement

data is recorded in the Measurement Log panel. You can customize the Measurement Log columns, sort data within

columns, and export data from the log to a tab-delimited, Unicode text file.

For a video on measurement features, see www.adobe.com/go/vid0029.

Measurement scale

Setting a measurement scale sets a specified number of pixels in the image equal to a number of scale units, such as

inches, millimeters, or microns. Once you’ve created a scale, you can measure areas and receive calculations and log

results in the selected scale units. You can create multiple measurement scale presets, although only one scale can be

used in a document at a time.

Scale markers

You can place scale markers on an image to display the measurement scale. Scale markers can appear with or without

a caption displaying measurement scale units.

Set the measurement scale (Photoshop Extended)

Use the Ruler tool to set the measurement scale for a document. You can create measurement scale presets for

frequently used measurement scales. Presets are added to the Analysis

measurement scale for a document is checked in the submenu, and appears in the Info panel.

Note: Measurement scale is set automatically for DICOM files. See “About DICOM files (Photoshop Extended)” on

page 603.

Choose Analysis > Set Measurement Scale > Default to return to the default measurement scale, 1 pixel = 1 pixel.
