IDL Routine Enhancements

The following IDL routines have updated keywords, arguments, or return values in this release. See the following topics in the IDL Reference Guide for complete reference information unless otherwise noted.

FFT

The FFT procedure has the following new keywords:

CENTER calculates a centered Fourier transform.

ICONTOUR, IIMAGE, IMAP, IPLOT, ISURFACE, IVECTOR, IVOLUME

The iTool routines have the following new keywords:

CURRENT_ZOOM is the zoom factor to be used for the current view.

DEPTHCUE_BRIGHT is the distance in the Z plane at which the objects in the view begin to fade into the background color.

DEPTHCUE_DIM is the distance in the Z plane at which the objects in the view have completely faded into the background color.

FONT_COLOR is the color of the text in the title annotation created by the TITLE keyword.

FONT_NAME is the name of the font used for the title annotation created by the TITLE keyword.

FONT_SIZE is the point size of the font used for the title annotation created by the TITLE keyword.

FONT_STYLE is the style of the font used for the title annotation created by the TITLE keyword.

STRETCH_TO_FIT indicates whether the visualizations should be stretched to fit within the view.

TITLE now creates a text annotation in the iTool window rather than specifying the text for the iTool window's title bar.

WINDOW_TITLE creates a title in the iTool window title bar.

XMARGIN is the horizontal margin size between the edge of the view and the edge of the visualization.

YMARGIN is the vertical margin size between the edge of the view and the edge of the visualization.

ZOOM_ON_RESIZE changes the size of visualizations when the window is resized.

IIMAGE

The IIMAGE procedure has the following new arguments and keywords:

The Filename argument is the name of a file that contains image data.

INTERPOL

The INTERPOL function has the following new arguments:

XOUT contains the abscissa values for the result. (Replaces the U argument.)

MAKE_DLL

The MAKE_DLL procedure has the following new keywords:

PLATFORM_EXTENSION causes MAKE_DLL to create a library file with a platform-specific file name.

MAKE_RT

The MAKE_RT procedure has the following new keywords:

OVERWRITE overwrites any existing files in the output directory.

SUNX86_64 creates a distribution for Solaris X86 machines running IDL in 64-bit mode.

MAP_PROJ_INIT

The MAP_PROJ_INIT function has the following new keywords:

ELLIPSOID sets the spheroid. (Replaces the DATUM keyword.)

MOMENT

The MOMENT function has the following new keywords:

MAXMOMENT limits the number of moments calculated.

OBJ_ISA

The OBJ_ISA function now accepts string class names in addition to object references when testing an object class for an "is a" relationship.

WIDGET_BUTTON

The WIDGET_BUTTON procedure has the following new keywords:

FLAT specifies that the button be created with a "flat" appearance rather than the default three-dimensional appearance.

WIDGET_COMBOBOX

The WIDGET_COMBOBOX procedure has the following new keywords:

FLAT specifies that the combobox be created with a "flat" appearance rather than the default three-dimensional appearance. Note that this keyword has no effect on Microsoft Windows systems.

WIDGET_DROPLIST

The WIDGET_DROPLIST procedure has the following new keywords:

FLAT specifies that the droplist be created with a "flat" appearance rather than the default three-dimensional appearance. Note that this keyword has no effect on Microsoft Windows systems.

WRITE_TIFF

The WRITE_TIFF procedure has the following new keywords:

COMPLEX writes the pixel components as complex floating-point entities (the default is 8-bit).

DCOMPLEX writes the pixel components as double-precision complex floating-point entities (the default is 8-bit).

DOUBLE writes the pixel components as double-precision floating-point entities (the default is 8-bit).

L64 writes the pixel components as unsigned 64-bit integer entities (the default is 8-bit). Use the SIGNED keyword to write signed integers.

SIGNED if the SHORT, LONG, or L64 keywords are set, SIGNED writes out signed integers instead of unsigned integers.
