CHAPTER 3: SELECTIONS & OBJECTS 139
Using the Measure Tool
The Measure Tool is composed of a Measure Handle and a Baseline , which are
adjustable points and lines used to take measurements of images, objects or
selections. The
Measure Handle is poled by a square node and a circular node,
each positioned by points X1 , Y1 and X2 , Y2 , respectively. The Baseline , on the
other hand, is a reference line for the angle measurement you make with the
Measure Handle. By default, the baseline is set at 0 degrees, which is parallel to
the image bottom. You can hide or show the baseline by clicking the toggle button
on the
Attribute Toolbar .
The Measure Tool helps you gain accurate information over dimensions,
distances, and angles of an image, text or object component. It is best used when
applying
Rotation and Transform effects that require precision placement, X and
Y coordinate positioning in image mapping, and encoding exact locations when
designing web pages.
To use the Measure Tool:
1. In the Toolbox , click the arrow on the Eyedropper and select the Measure
Tool .
2. Define the Measure Handle by clicking a starting point anywhere in the image
then dragging the mouse to the ending point of what you want to measure.
When the mouse button is released, the
Measure Handle will appear together
with the Baseline .
Tip: You can show/hide the baseline by clicking Baseline on the Attribute Toolbar .
3. You can now drag the poles to resize the Measure Handle and the Baseline ,
or drag the middle box to reposition the measure line in your image.
All values, distance, length, or angle, are displayed on the
Attribute Toolbar .
You can use these values to compute differences when applying Transform ,
Rotate , or other effects.
