Defines the assignment of the axes to the indices of the data matrix (img file) stored in the Analyze 7.5 format (see ImportAnalyze75Data). The axes are represented by the characters X, Y, L (layer) and T (time slot). The first axis is the one which corresponds to the inner most index (the fastest changing index), the last to the outer most index of the matrix. 
TAna75SpecTypes = (stTHzSpec, stUvVis, stIRspec, stIRdiscrete, stRaman, stMSpec, stSIMS, stRGBcolors); 
Defines the supported spectral types stored in Analyze 7.5 format (see ImportAnalyze75Data). 
TAlign = (alNone, alTop, alBottom, alLeft, alRight, alClient, alCustom); 
Specifies how a control is placed relative to its parent; see ChartX.Align for details.

TAlignment = (taLeftJustify, taRightJustify, taCenter); 
Specifies how text is aligned:
taLeftJustify ... text is leftjustified
taCenter ... text is centered around the anchor position
taRightJustify ... text is rightjustified

TBLMode = (blNone, blLinear, blP1Level); 
Determines the type of the baseline reference used in some types of spectral descriptors (function AddSpdc) 
TBool2DArray = array of array of boolean; 
Declares a twodimensional open array of boolean values. The first index corresponds to the columns of the matrix, the second index to the rows. 
TBoolArray = array of boolean; 
Declares an open array of boolean values.

Declares a color value. 
TColorPalette = array[1..500] of TColor; 
Declares a color palette. 
TCompareMode = (cmLT, cmGT, cmLE, cmGE, cmEQ, cmNE); 
Defines the type of comparison in the MaskByThresholdArr and MaskByThresholdCube functions. 
TCrossHMode = (chOff, chHoriz, chVert, chBoth, chCrossBox, chBox); 
Declares the available kinds of crosshairs:
chOff ... crosshair is switched off
chHoriz ... only vertical information of crosshair position is displayed (as horizontal line across the chart)
chVert ... only horizontal information of crosshair position is displayed (as vertical line across the chart)
chBoth ... full crosshair with lines across the entire chart area
chCrossBox ... small crosshair with a "bull eye"
chBox ... a square box of 8x8 pixels

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. 
TDoubleArray = array of double; 
Declares an open array of double precision numbers (a "data vector"). 
TDouble2DArray = array of array of double; 
Declares a twodimensional 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 threedimensional 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 littleendian byte order (used on PC/Intel machines), edUnixMac means bigendian byte order (used on UNIX and Macintosh machines).

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])

TFFTPadding = (ftpZero, ftpLevel, ftpMirror);
