iTool Enhancements

The IDL Intelligent Tools (iTools) are a set of interactive utilities that combine data analysis and visualization with the task of producing presentation quality graphics. Introduced in IDL 6.0, the iTools are designed to help you get the most out of your data with minimal effort. They allow you to benefit from the control of a programming language, while accelerating your data analysis through the use of interactive utilities.

For details on these additions and other enhancements that have been made to the IDL iTools system for the 6.4 release, see the following topic:

New and Enhanced iTools Keywords

ANISTROPIC_SCALE_2D — This keyword indicates the ratio of the Y dimension to the X dimension for two-dimensional images. Applies to: all iTools.

ANISTROPIC_SCALE_3D — This keyword indicates the ratio of the Z dimension to the X and Y dimensions for three-dimensional images. Applies to: all iTools.

FIT_TO_VIEW — This keyword automatically scales the newly-created visualization so that it fills the current view. Applies to: all iTools.

GEOTIFF — This keyword allows GeoTIFF structures to be passed into iMap. Applies to: IMAP.

INSERT_COLORBAR — This new keyword allows you to display a colorbar automatically in your iTool. Applies to: all iTools.

INSERT_LEGEND — This keyword automatically inserts a legend into your visualization. Applies to: ICONTOUR, IPLOT, and ISURFACE.

MAX_VALUE — This keyword indicates the maximum value to be plotted. Applies to: ICONTOUR and ISURFACE.

MIN_VALUE — This keyword indicates the minimum value to be plotted.Applies to: ICONTOUR and ISURFACE.

RGB_TABLE — This keyword has been enhanced to accept an IDL colorstyle number. Applies to: all iTools.

RENDERER — This keyword overrides the value specified by the IDL_GR_WIN_RENDERER (Windows) or IDL_GR_X_RENDERER (UNIX) preference for the iTool. Applies to: all iTools.

SCALE_ISOTROPIC — This keyword indicates the scaling method to be used for the dataspace. Applies to: all iTools.

SYM_COLOR — This keyword specifies the color for the missing-point symbols. Applies to: IVECTOR.

SYM_INDEX — This keyword specifies the symbol to be used for missing points. Applies to: IVECTOR.

SYM_OBJECT — Provides the ability to define and select user-defined plot symbols. Applies to: IPLOT.

SYM_SIZE — This keyword specifies the size of the missing-point symbols. Applies to: IVECTOR.

TRANSPARENCY — This keyword specifies the percent transparency of the visualization. Applies to: ICONTOUR, IIMAGE, IPLOT, ISURFACE, and IVECTOR.

USE_DEFAULT_COLOR — This keyword specifies the use of the color of the vectors for the missing-point symbols (this is the default). Applies to: IVECTOR.

VIEW_ZOOM — This keyword sets the initial view zoom factor. Applies to: all iTools.

[XYZ]LOG — These keywords specifies a logarithmic axis. Applies to: ICONTOUR, ISURFACE, and IVECTOR.

Image Plane Location Control

A new Image Plane Location property now allows you to specify the exact data location of the image plane.

TrueType Font Availability

iTools can now use any TrueType font available on your system. For more information, see [XYZ]TICKFONT_INDEX under any of the iTools Routines.

Z Values for iMap's Graphic Layers

Map Gridlines, Shapefile Polygons, Polylines, and Points visualizations now have a new Z value. If multiple images are displayed in a stack you can now specify the corresponding Z value for the graphics so that any or all of the images can have graphics drawn on them.
