Using SonarWave Lite, you can adjust the on-screen color table to enhance features and improve contrast in XTF sidescan files.
SonarWave Lite uses linear grey as the default color table. Other color tables available are blue and sepia. The user can change the color table at any time on an open XTF file. Any of the three color tables work with the gamma or equalization options described below.
Applying a Gamma Correction
You can use a Gamma correction to visually enhance the on-screen display of a low-contrast XTF sidescan file.
Applying a Gamma correction lets you adjust the contrast and brightness that affect the midtones of an XTF sidescan file. The Gamma slider ranges between 0.1 to 5.0, with a default of 1.0.
Equalizing the Color Table
The Equalizing feature redistributes a narrow range of amplitudes equally over the tonal range in an XTF sidescan file to improve the contrast.
Inverting the Color Table
You can invert the on-screen color table of an XTF file. This reverses the color table. The dark tones become light, and the light tones become dark.
