Selecting Display Color Space
Note:
Use the list
at the top of the COLOR window to select the color
space to be used for displaying color values. ORIS PDF Tuner supports
the CMYK, RGB, HSB and CIE color space.
If the image type and the display color space selected in the COLOR window
are different, the values corresponding to the image’s color space
are averaged and the result is converted into the values of the display
color space. For example, when you measure an RGB image using the
CMYK color space, the RGB color values are averaged and the result is
converted to CMYK.
Comparing Image Colors
During image manipulations the COLOR window displays two sets of color
values separated by a slash. The colors on the left refer to the modified
image, the colors on the right to the original unmodified image. This
feature is not available for linework.

Defining Size of Measured Area
By default, a single pixel is measured only, but you can also measure the
colors over an area of up to 32 x 32 pixels. In this case the COLOR window
(see Fig. 30-8) displays average values.
To define the size of the measured pixel area, select COLOR MEAS. BOX
in the MENU window and enter the size into the input box. Enter e.g. 10
to measure an area of 10 x 10 pixels, enter 1 to measure only a single
pixel. The current size is indicated on the title bar of the COLOR window.
Displaying Box Cursor
You can display the cursor as a box that encloses the pixel area you are
measuring. SHIFT-click to toggle between cross-hair cursor and box cursor.
