-
- Overview
- This appendix describes the meaning of many of NCSA
- ImageTool's error numbers and warning messages, as well as
- some operation system errors. Instructions to correct specific
- problems are included.
-
-
- NCSA ImageTool Error Messages
-
- Error, warning, and status messages appear in the message panel.
- The panel numbers actions or their results from 1 to 20, then begins
- again at 1. The scroll bar to the left of the panel lets you move
- forward and backward through the entries.
-
- Table 3.1 lists errors that can be easily corrected in most
- instances.
-
-
- Table B.1 Error Numbers,
- Meanings, and
- Corrections
- Error Number Meaning and Correction
-
- 2 Filename is missing from the NCSA
- ImageTool control panel. Enter a character
- string in the Image text field (click the
- mouse next to the text item "Image" and type
- the string).
-
- 3 The file was not found when NCSA
- ImageTool tried to load it. Check to see if
- you typed in the correct filename or you are
- using the correct working directory.
-
- 4 Filename is ambiguous. This happens
- when you have *, ?, or other wildcard
- characters in the name string that represent
- more than one file in the current working
- directory. Therefore, check the filename.
-
- 5 Image dimensions are missing. Enter
- integers on the text items Xdim and Ydim on
- the NCSA ImageTool control panel.
-
- Table B.1 Error Numbers,
- Meaning, and
- Correction (Cont'd)
- Error Number Meaning and Correction
-
- 6 Image dimensions are larger than the full
- screen size of 1150 x 900 pixels.
-
- 7 Error in opening a file to read. If you are
- running on a networked disked disk, this
- could occur if files are not found or there is a
- file server problem
-
- 8 Error in opening a file to write. Check the
- permission levels for the file and directory
- to which you are writing.
- 9 SunView lib call memcreate() failed. The
- system could be out of memory.
-
- 10 UNIX call malloc() or calloc() failed.
-
- 11 Error in reading a file.
-
- 12 Error in writing a file. Check the directory
- permissions.
-
- 13 Negative input for logarithmic functions.
- Make sure your input is positive when you
- use logarithmic scaled computations.
-
- 14 UNIX library call tempnam() failed (that
- is, the system cannot create a tmp file in
- /usr/tmp). This is due to a space problem.
-
- 15 SunView call textswstorefile() failed
- (cannot write the content of the text window
- to a disk file). Check the disk space.
-
- 16 UNIX call chdir() failed. Check the
- directory pathname.
-
- 17 Syntax error with a UNIX name string.
-
- 18 No FTP connection when selecting the Get
- Loop option. Select Connect from the FTP
- menu first.
-
- 19 Unknown strings in the default file
- .imagetool_defaults. Use the Set
- defaults option from the Option menu to
- set up the default file.
-
- 20 Unknown font. NCSA ImageTool could not
- find the specific font in
- /usr/lib/fonts/fixedwidthfonts.
-
-
- NCSA ImageTool Warning Messages
-
- Warnings are not catastrophic failures, but the warnings in Table
- B.2 indicate a situation that may require attention.
-
-
- Table B.2 Warning Numbers
- and Descriptions
- Warning Number Description
-
- 25 Fewer bytes read from an image file. Either
- you have opened a bad image file or
- specified the wrong dimensions.
-
- 26 Fewer bytes than specified written to a file.
- The system may be out of disk space.
-
- 27 The raster format selected is not supported
- in the current version.
-
- 28 The expansion factors are missing, and you
- have selected Expand from the Zoom menu.
- You must provide two integer expansion
- factors in the pop-up dialog box. The default
- factors are set to 1 x 1.
-
- 29 The default file is missing. If you do not
- have a default file, .imagetool_defaults,
- in your home directory, NCSA ImageTool
- assumes the current directory is the default.
- NCSA ImageTool contains the images,
- palettes, and help files. You may select Set
- defaults from the Options menu to
- change the defaults.
-
-
- SunView and Operating System Errors
-
- Operating system errors (Table B.3) indicate problems in
- operating NCSA ImageTool or Suntool. These errors are not easily
- recoverable, and may require the assistance of a system
- administrator.
-
- Table B.3 SunView and
- Operating System
- Errors
- Number Cause and Solution
-
- 9 SunView library call memcreate() failed. The
- system memory could be depleted.
-
- 10 A UNIX memory allocation call,
- malloc() or calloc(), failed. Virtual memory
- space may be depleted.
-
- 11 An error occurred while the system was
- reading a file. This should never happen. It could
- be caused by a system problem.
-
- 12 An error occurred while the system was
- writing a file. You may have run out of disk space
- on the volume to which you were writing.
-
- 14 The UNIX library call tempnam() failed. Space
- could not be allocated in the /usr/tmp directory.
- Check the available disk space on the /usr disk.
-
- 15 The SunView call textswstorefile() failed.
- The textswstorefile() call attempts to store the
- contents of a text window to a file. If this call fails,
- you may have run out of disk space.
-
- 20 NCSA ImageTool could not find the font it uses in
- the directory
- /usr/lib/ fonts/fixedwidthfonts.
-
-
- Numerical Problems
-
- 13 The input value for a logarithmic function was
- negative. Make sure that input to a logarithmic
- scaling function is positive.
