Dye/Tint

The Dye/Tint feature allows you colorize grayscale images to highlight objects of interest.  When you click on the Dye/Tint tool, a dialog box appears with the following tools.

Tint Image On/Off:  Check/uncheck this box to enable/disable the colorization of the image.  When checked, the image is tinted according to the Tint Color or Hue value (described below).  When unchecked, the image is not tinted.

Add to Color Composite: Check this box to add the tinted image to an active Color Composite window.

Dye: This list box lists all currently-defined dyes for the currently-selected *.Dye file.  Each dye listed represents a color that is associated with an emission wavelength.  When you select a dye, the Dye/Tint group box is updated to show the selected dye's Emission Wavelength and Hue properties, and the image is colorized according to the Hue property.  

Note: Click on the Configure tool to access the Dye Editor where you can manage the current list of dyes or load an entirely different set of dyes (i.e., a different *.Dye file).

Emission wavelength: If a Dye is selected, this field displays the emission wavelength specification for the selected dye. You can, however, adjust the emissions wavelength by entering a new value in the spin box or by clicking on the Emission Wavelength color continuum. The image tint will change in response to changes in the emission wavelength.  Image-Pro automatically selects the default tint associated with the specified emission wavelength.

Tint Color:  Use this control to select a custom color to tint the image. This control differs from the Hue control in that it provides access to the full range of 24-bit colors for tinting the image.  If you select a color using the Hue value, then that selection will automatically be assigned to the Tint Color control as well.

Hue: Use this control to select a custom color to tint the image. If a Dye is selected, the Hue value will default to the value associated with the dye's Emission Wavelength specification. Similarly, if you change the Emissions Wavelength value, the Hue control will be updated to reflect the standard color for that wavelength. To set a custom Hue, first you should set the wavelength and then edit the Hue.
