RTD [incr Tcl] Widget Classes

The RTD software includes a library of [incr Tcl] widget classes 1 . Some of these widget classes are based on the rtdimage extension or are designed to be used with it and some are simply general user interface components. Here is a list of the widgets designed to work with the rtdimage extension directly: (see the User's Guide for screendumps of these widgets):

RtdImageColorRamp	Makes a color ramp or bar, used to display the colors in the colormap and manipulate the colormap by rotating, shifting, stretching, etc.
RtdImageColors	Popup window for selecting a colormap, intensity, color scaling algorithm and for controlling the number of colors allocated.
RtdImageCtrl	Combination of other widgets: displays the image with a zoom window, panning window, control panel and color ramp. Adds support for application menu commands.
RtdImageCut	Popup window displaying the pixel value distribution and various ways of setting the image cut levels.
RtdImageFrame	Widget for displaying a rapid frame displaying a section of the image in the image window.
RtdImagePanel	Control panel and information display for an RtdImage widget, displays X,Y coordinates, world coordinates and pixel values, min and max pixel values, low and high cut levels. Supports scaling, rotating, flipping the image.
RtdImagePerf	Widget for displaying interactive performance testing data when the facility is toggled on by the perftest rtdimage subcommand.
RtdImagePick	Popup window to pick a star or object in the image and display statistics, such as FWHM, position, angle, etc.
RtdImagePopup	A top level widget for displaying a section of the image and zoom controls, also for use as a rapid frame.
