Color Tables

There are 26 available color scales. For instance, Color Table 0 is grayscale while Color Table 1 features blue.

You may change the Color Table by entering a color table number into the Table dialog box. You may also make that the default color table for new files.

Table 1 displays a list of the 26 NanoScope color tables with Contrast = 0 and Offset = 0.

Data Scale

Set the Data Scale in the Color Scale window to set the data range.

Offset and Contrast

Both Contrast and Offset, adjustable in the Color Scale window, have a major effect on displayed colors. An example is shown for Color Table 12 in Figure 2.

Offset - Number (–128 to +128) designates offset colors in the displayed image (e.g., 120 shows illuminated background on image). Offset effectively changes the color value around which the color scale is mapped.

Contrast - Number (–10 to +10) designates contrast of colors in displayed image (e.g., –10 shows little change while 10 shows highest contrast)
