uvfconvert - convert files to UVF. SYNOPSIS
uvfconvert -i file [ options ] -o output DESCRIPTION
uvfconvert is a command line tool to convert data into UVF, the native format for the desktop volume rendering program imagevis3d. Unlike ImageVis3D, the tool can be run on headless nodes with no GPUs installed, and utilizes very little memory even for extremely large data. OPTIONS
The command line options of uvfconvert are: -i filename, --input filename The input data set to convert. Must be in one of ImageVis3D's supported file formats (see the "Getting Data Into ImageVis3D" man- ual). For merging multiple data sets, this option is accepted multiple times. -d path, --directory path Input data to convert, if stored as a stack in a directory. Sets of images or DICOMs commonly come in this format. One of -i or -d is required. -s floating point number, --scale floating point number Optional. When merging multiple data sets, this scaling factor will be applied to all values in the second file. Defaults to 0.0. -b floating point number, --bias floating point number Optional. When merging multiple data sets, this bias factor will be applied to all values in the second file. Defaults to 0.0. -o filename, --output filename Required. The filename which will be generated. --version Optional. Display a version number and then exit. --, --ignore-rest Optional. Any arguments following these flags will be ignored by the program. AUTHOR ImageVis3D and all associated software was written at the SCI Institute, with support from the NIH NCRR and DoE VACET programs. Our primary source of funding comes from demonstrating that our software enables research. Please contact us if you find ImageVis3D beneficial. SCI

fp2hdf - convert floating point data to HDF SYNOPSIS
fp2hdf -h[elp] fp2hdf infile [infile...] -o[utfile outfile] [-r[aster] [ras_options...]] [-f[loat]] DESCRIPTION
fp2hdf converts floating point data to HDF Scientific Data Set (SDS) and/or 8-bit Raster Image Set (RIS8) format, storing the results in an HDF file. The image data can be scaled about a mean value. Input file(s) contain a single two-dimensional or three-dimensional floating point array in either ASCII text, native floating point, or HDF SDS format. If an HDF file is used for input, it must contain an SDS. The SDS need only contain a dimension record and the data, but if it also contains maximum and minimum values and/or scales for each axis, these will be used. If the input format is ASCII text or native floating point, see "Notes" below on how it must be organized. OPTIONS
-h[elp] Print a helpful summary of usage, and exit. -o[utfile] outfile Data from one or more input files are stored as one or more data sets and/or images in one HDF output file, outfile. -r[aster] Store output as a raster image set in the output file -f[loat] Store output as a scientific data set in the the output file. This is the default if the "-r" option is not specified. ras_opts: -e[xpand] horiz vert [depth] Expand float data via pixel replication to produce the image(s). horiz and vert give the horizontal and vertical resolution of the image(s) to be produced; and optionally, depth gives the number of images or depth planes (for 3D input data). -i[nterp] horiz vert [depth] Apply bilinear, or trilinear, interpolation to the float data to produce the image(s). horiz, vert, and depth must be greater than or equal to the dimensions of the original dataset. -p[alfile] palfile Store the palette with the image. Get the palette from palfile; which may be an HDF file containing a palette, or a file containing a raw palette. -m[ean] mean If a floating point mean value is given, the image will be scaled about the mean. The new extremes (newmax and newmin), as given by: newmax = mean + max(abs(max-mean), abs(mean-min)) newmin = mean - max(abs(max-mean), abs(mean-min)) will be equidistant from the mean value. If no mean value is given, then the mean will be: 0.5 * (max + min) INPUT
If the input file format is ASCII text or native floating point, it must have the following input fields: format nplanes nrows ncols max_value min_value [plane1 plane2 plane3 ...] row1 row2 row3 ... col1 col2 col3 ... data1 data2 data3 ... ... Where: format Format designator ("TEXT", "FP32" or "FP64"). nplanes Dimension of the depth axis ("1" for 2D input). nrows Dimension of the vertical axis. ncols Dimension of the horizontal axis. max_value Maximum data value. min_value Minimum data value. plane1, plane2, plane3, ... Scales for depth axis. row1, row2, row3, ... Scales for the vertical axis. col1, col2, col3, ... Scales for the horizontal axis. data1, data2, data3, ... The data ordered by rows, left to right and top to bottom; then optionally, ordered by planes, front to back. For FP32 and FP64 input format, format, nplanes, nrows, ncols, and nplanes are native integers; where format is the integer repre- sentation of the appropriate 4-character string (0x46503332 for "FP32" and 0x46503634 for "FP64"). The remaining input fields are composed of native 32-bit floating point values for FP32 input format, or native 64-bit floating point values for FP64 input format. EXAMPLE
Convert floating point data in "f1.txt" to SDS format, and store it as an SDS in HDF file "o1": fp2hdf f1.txt -o o1 Convert floating point data in "f2.hdf" to 8-bit raster format, and store it as an RIS8 in HDF file "o2": fp2hdf f2.hdf -o o2 -r Convert floating point data in "f3.bin" to 8-bit raster format and SDS format, and store both the RIS8 and the SDS in HDF file "o3": fp2hdf f3.bin -o o3 -r -f Convert floating point data in "f4" to a 500x600 raster image, and store the RIS8 in HDF file "o4". Also store a palette from "palfile" with the image: fp2hdf f4 -o o4 -r -e 500 600 -p palfile Convert floating point data in "f5" to 200 planes of 500x600 raster images, and store the RIS8 in HDF file "o5". Also scale the image data so that it is centered about a mean value of 10.0: fp2hdf f5 -o o5 -r -i 500 600 200 -m 10.0 SEE ALSO
