Using The Sample Size Button; Value And Percent - Microtek ScanMaker 35T Plus User Manual

Using the Sample Size button

The Sample Size button provides options for choosing how extensively the color
information will be read — whether the color information will apply to a pixel, a 2-pixel
by 2-pixel area, or a wider expanse (maximum 5-pixel by 5-pixel area).
When you click on the Sample Size button, the drop-down menu below appears:

Value and Percent

• If you choose Value, the numbers in the Color Meter Display represent the values in
the 0-to-255 pixel scale. For instance, an R value of 23 indicates that the sampling size
selected has a red color value of 23. Value is calculated by multiplying the percentage
by the constant 255 (value = 255 x percent).
• If you choose Percent, the numbers represent the percentage of the maximum intensity
of the pixel. For instance, a G value of 35% indicates that the sampling size selected
has a green color value to be 35 percent intense (out of 100 percent). Percent is
calculated by dividing the constant 255 by the value (percent = 255
