Measurement Data Points
Angle of orientation (±0-180) of the Ruler tool.
Area of selection in square pixels, or in calibrated units according to the current measurement scale (such as square millimeters).
4pi(area/perimeter ). A value of 1.0 indicates a perfect circle. As the value approaches 0.0, it indicates an increasingly elongated
polygon. Values may not be valid for very small selections.
Varies according to the measuring tool used. Selection tool: the number of discontiguous selection areas on the image. Count tool: the
number of counted items on the image. Ruler tool: the number of Ruler lines visible (1 or 2).
Applies a date/time stamp of when the measurement occurred.
Identifies the document (file) measured.
This is a measurement of brightness, either from 0 to 255 (for 8-bit images), 0 to 32,768 (for 16-bit images), or 0.0 to 10 (for 32-bit
images). For all gray value-related measurements, the image is internally converted to grayscale (equivalent to choosing Image > Mode >
Grayscale) using the default grayscale profile. Then the requested calculations (mean, median, minimum, maximum) are calculated for each
feature and for the summary.
Height of the selection (max y - min y), in units according to the current measurement scale.
Generates histogram data for each channel in the image (three for RGB images, four for CMYK, and so on), recording the number of
pixels at each value from 0 to 255 (16-bit or 32-bit values are converted to 8-bit). When you export data from the Measurement Log, the numeric
histogram data is exported to a CSV (comma-separated value) file. The file is placed in its own folder at the same location where the
measurement log tab-delimited text file is exported. Histogram files are assigned a unique number, starting at 0, and progressing by 1. For multiple
selections measured at once, one histogram file is generated for the total selected area, plus additional histogram files for each selection.
The sum of the values of the pixels in the selection. This is equivalent to the product of Area (in pixels) and Mean Gray Value.
Identifies and automatically numbers each measurement as Measurement 1, Measurement 2, and so on. For multiple selections measured
simultaneously, each selection is assigned an additional Feature label and number.
Linear distance defined by the Ruler tool on the image, in units according to the current measurement scale.
The perimeter of the selection. For multiple selections measured at once, one measurement is generated for the total perimeter of all
selections, plus additional measurements for each selection.
The measurement scale of the source document (for example, 100 px = 3 miles).
Logical units of the measurement scale.
The number of pixels assigned to the scale unit.
Source of the measurement: Ruler tool, Count Tool, or Selection.
Width of the selection (max x - min x), in units according to the current measurement scale.
