mPNGWWTExec
- Description:
- Runs mViewer for all the tiles needed for a WWT TOAST set. FITS tile files should already have been generated using mProjWWTExec.
- Syntax:
- mPNGWWTExec [-d lev] colorTable tileLevel baseName grayDir gray.hist pngDir
mPNGWWTExec -c [-d lev] trueColor tileLevel baseName blueTileDir blue.hist greenTileDir green.hist redTileDir red.hist pngDir
Switches:
- -c
- Switches to color mode (different argument set)
- -d level
- Turns on debugging to some level
Arguments (grayscale mode):
- colorTable
- The grayscale color table. See mViewer docs for details.
- tileLevel
- The depth of WWT TOAST tiles desired. This should be no bigger than the depth to which FITS files were created.
- baseName
- Base name for tiles. For instance, an output tile named "planck3102.png" has the base name "planck".
- grayDir
- Directory containing grayscale FITS TOAST files, previously created with mProjWWTExec.
- gray.hist
- Histogram used for stretching grayscale FITS files, previously created with mHistogram.
- pngDir
- Directory for output PNGs.
Arguments (color mode):
- trueColor
- Color enhancement parameter. See mViewer docs for details; set to zero for no special enhancement.
- tileLevel
- The depth of WWT TOAST tiles desired. This should be no bigger than the depth to which FITS files were created.
- baseName
- Base name for tiles. For instance, an output tile named "planck3102.png" has the base name "planck".
- blueDir
- Directory containing blue FITS TOAST files, previously created with mProjWWTExec.
- blue.hist
- Histogram used for stretching blue FITS files, previously created with mHistogram.
- greenDir
- Directory containing green FITS TOAST files, previously created with mProjWWTExec.
- green.hist
- Histogram used for stretching green FITS files, previously created with mHistogram.
- redDir
- Directory containing red FITS TOAST files, previously created with mProjWWTExec.
- red.hist
- Histogram used for stretching red FITS files, previously created with mHistogram.
- pngDir
- Directory for output PNGs.
- Results:
- Like mProjWWTExec, this utility has a limitation: all the output files are put in a single directory. This may become unworkable if the tiles go deep enough. This shortcoming can be easily overcome but the details will depend on the details of the input data so we have opted for a simple initial approach.
Examples:
- $ mPNGWWTExec -d 1 4 4 Planck fits gray.hist pngs
- [struct stat="OK", level=4, nimage=341]
Return Codes:
- [struct stat="OK", level=level, nimage=count]
- [struct stat="ERROR", msg="Usage: mPNGWWTExec [-d lev] colorTable tileLevel baseName grayDir gray.hist pngDir | mPNGWWTExec [-d lev] -c trueColor tileLevel baseName blueTileDir blue.hist greenTileDir green.hist redTileDir red.hist pngDir"]
- [struct stat="ERROR", msg="Problem with FITS file."]
- [struct stat="ERROR", msg="Cannot find histogram file [histfile]."]
- [struct stat="ERROR", msg="[dir] is not a directory."]
- [struct stat="ERROR", msg="Problem creating output PNG directory."]
- [struct stat="ERROR", msg="Problem with output PNG directory."]
- [struct stat="ERROR", msg="mViewer error message"]
