ILabPascal - Special Data Types [D..F]

In addition to the standard data types of ILabPascal the scripting engine provides several predefined data types which are specifically needed in some function calls.

Declaration Explanation & Details
TDataPoint = record
               XPos    : double;
               YPos    : double;
               ClassIx : integer;
Declares a data point as it is used in the Dataset Editor.
TDateTime = double; Defines the date/time data type. The integral part is the number of days that have passed since December 30, 1899. The fractional part is the time of day. The maximal correct date supported is limited to December 31, 9999 23:59:59:999.
TDims = (dimX, dimY, dimL, dimT); Defines the four dimensions of the hypercube. dimX and dimY are the lateral dimensions, dimL corresponds to the spectral dimension and dimT represents the time axis.
TDirection = (dirUpward, dirDownward, dirLeftward, dirRightward); The type definition TDirection specifies the four principal directions on the screen.
TDoubleArray = array of double; Declares an open array of double precision numbers (a "data vector").
TDouble2DArray = array of array of double; Declares a two-dimensional open array of double precision numbers (a "data matrix"). The first index corresponds to the columns of the matrix, the second index to the rows.
TDouble3DArray = array of array of array of double; Declares a three-dimensional open array of double precision numbers (a "data cuboid"). The first index corresponds to the columns of the matrix (dimX), the second index to the rows (dimY), the third index designates the layers of the cuboid (dimL).
TEndian = (edWindows, edUnixMac); Declares the endianess of binary data. edWindows means little-endian byte order (used on PC/Intel machines), edUnixMac means big-endian byte order (used on UNIX and Macintosh machines).
TEnviDataType = (dt1Busi, dt2Bsi, dt4Bsi, dtSingle,
dtDouble, dtCSingle, dtCDouble, dt2Busi, dt4Busi,
dt8Bsi, dt8Busi, dtUnknown);
Declares the various supported data types of ENVI files.
TEnviHeader = record
                NumX        : integer;
                NumY        : integer;
                NumL        : integer;
                DataTp      : TEnviDataType;
                SenseTp     : TEnviSensorType;
                HdrOfs      : integer;
                ILeave      : TEnviInterLeave;
                ByteOrder   : TEndian;
                WLUnits     : string;
                WaveL       : TDoubleArray;
                Description : string;
                TimeStamp   : TDateTime;
                PixelSizeX  : double;
                PixelSizeY  : double;
                TilePosition: TPoint;
                FwHm        : TDoubleArray;
                LinkedFiles : array of string;
                FileType    : TIlabFileType;
                AcqTime     : TIntArray;
                SpecNames   : array of string;
Declares the ENVI header specification.
TEnviInterLeave = (ilBSQ, ilBIL, ilBIP); Declares the data order used in ENVI binary files (see also SaveENVI)
ilBSQ - Band Sequential (X[col,row,band])
ilBIL - Band Interleave by Line (X[col,band,row])
ilBIP - Band Interleave by Pixel (X[band,col,row])
TEnviSensorType = (estSpero, estUserDefined, estIRspec,
estMSPos, estMSPosRaw, estMSNeg, estMSNegRaw, estMSsim,
estLibsRaw, estLibsSl, estRaman, estUvVis, estRGBcolors,
estTHzSpec, estImpulse, estOESRaw, estOESsl, estEDX,
estSIMS, estIRdiscrete, estMagSpec, estPhaseSpec,
estPowerSpec, estUnknown);
Declares various sensor types for ENVI. Please note that this declaration is proprietary and not part of the ENVI specification
TFeatKind = (fkUndefined, fkInteger, fkDouble, fkString, fkTriState); Declares the type of features used in a feature matrix, see TFeatKind for details.
TFFTPadding = (ftpZero, ftpLevel, ftpMirror); Specifies the type of padding to be used for the Fourier transform if the data sample does not contain a number of data points which is a power of 2.
TFFTResult = (ftrReal, ftrImag, ftrMag,
ftrPhase, ftrPower);
Specifies the type of result produced by the function FFTofCubeData.
TFastFourierWgtWin = (fwRectangle,
fwTriangle, fwCos2, fwGauss,
fwHamming, fwBlackman, fwBlkmHarris,
fwBlkmNuttall, fwUserDef);
The type of windowing function used by the function FFT.
TFont = class(TGraphicsObject) TFont describes font characteristics used when displaying text.
TFrameStyle = (fsNone, fsSimple, fsLowered, fsRaised, fsEmbossed, fsEngraved); Defines the possible variations of the frame of a rectangular area.
