%  PROGRAM
% vcast1 - Upcast Images to the Highest Input Data Type
%
%  DESCRIPTION
% .I vcast1
% This is a modified version of Khoros' vcast. Scaling and Normalization are turned off, so that BIT to BYTE_1 conversion yields pixel values of 0 or 255 on the BYTE image.
% will upconvert or upcast each input image to the highest input image
% data type.  Optionally, the user may elect to upcast all images to 
% a specified data type, as long as it is a data type that is equal to
% or greater than the highest data type of the input images.  If the
% user tries to select a data type that is lower than the highest 
% data type of the input images, an error message will be produced
% indicating that down casting is not allowed.
% 
% There are no restrictions as to the input image data types.  The data
% types can range from BIT to DOUBLE.  The input images may contain any
% combination of sizes or number of data bands.  All map information from 
% each input image is transferred to the corresponding output image. 
% 
% Note that when converting from type BIT to BYTE, the output values
% will be 0 or 1.  This is different from the results one would obtain
% using the defaults with vconvert.  In trying to preserve the 
% integrity of the data, vcast1 scales the data by 1.
%
%  
%
%  EXAMPLES
% vcast1 -i1 image.bit -i2 image.float -o1 image1 -o2 image2
% 
% converts both input images to data type FLOAT.  The optional data
% type argument was not selected, so auto convert was used to cast
% both images to the highest data type of the input images (in this case
% FLOAT).
% 
% vcast1 -i1 image.bit -i2 image.byte -i3 image.short -o1 img1 -o2 img2 -o3 img3 -t float
% 
% converts each input image to data type FLOAT.  The optional data 
% type argument was used to upcast all input images to data type
% FLOAT.
%
%  "SEE ALSO"
% vconvert(1)
%
%  RESTRICTIONS 
% .I vcast1
% only scales the input data by 1, and will only upconvert the data.
