The following options can be applied regardless of the type of sourceFile.
Folder in which output files are to be placed (including the log file, if -log is specified). May be an absolute path or relative to the current working directory. The folder hierarchy will be created if it does not exist. Does not apply to the file specified with -log . If not specified, output files are written to the folder in which sourceFile is located. If destFile is specified, it will always be written to that location, and -destpath only applies to the secondary output files.
If specified, the (first) view image is extracted from the vignette, a suitable panel image from a cabinet style, or the first illumination image of a window covering style. The extracted image is saved as a full-resolution TIFF file.
Prevents generation of target files. Useful to quickly extract attributes from sourceFile . Only the optional thumbnail ( -thumbwidth ), image ( -image ) and log files ( -log ) are generated.
Selects lossy JPEG encoding for RGB and gray-scale image data embedded in the output file, instead of lossless PNG. Images with alpha (RGBA) are always saved using PNG encoding. ival specifies the JPEG quality (1...100); 85 or higher is recommended. Default is -jpegquality 0 , which selects PNG encoding.
Creates a log file with the specified path/name The full paths of all output files written to the destination folder are written to the log file, as well as some additional settings, such as version info and any warnings or errors encountered (see Output for details). No log file is created if -log is not specified; in this case, all text output is written to stdout .
Lower the priority of the vntc process. This can be used so that vntc won't take over an entire CPU while processing a vignette. It allows the operating system to give more time to other, more important, processes. ival specifies the lower priority percentage (0..100). Default is -lowerpriority 0 , which does not lower the priority of the vntc process.
Specify the maximum amount of memory that vntc is allowed to use in bytes. When vntc reaches the maximum memory limit, it stops processing and produces an error. ival specifies the maximum memory limit in bytes (0.. 3,758,096,384 (3.5GB)). When ival is 0, the maximum memory limit is turned off. Default is -maxmem 3221225472 , which means a maximum memory limit of 3 GB.
-separator " string "
Specifies the separator placed between the filename and the size/resolution suffix for auto-generated output file names. Defaults to "-" if not specified. Ignored if destFile or -info is specified.
Enables sharpening of images resampled (scaled) during processing. Only applies to thumbnail sharpening in case of cabinet style files.
Specify 0 to disable sharpening (default), 1 to enable normal sharpening, 2 to enable unsharp-masking for brightness only, or 3 to enable unsharp-masking for each color component.
Sets the log level. Default is 1, which outputs all informational, warning, and error messages. Set to 0 to disable all but error messages.
-usm amount radius threshold
Sets the unsharp-masking parameters. Ignored if -sharpen is set to 0 or 1; required if -sharpen is set to 2 or 3. amount is a real value in the range 0.0...500.0, radius is a real value in the range 0.0…10.0, and threshold is an integer between 0 and 255. Refer to the description of op_usm= in the Image Serving Protocol Reference for additional information.
Validate that the given vignette is a proper production vignette. ival represents the minimum file version of the vignette.
File version for the output file. If specified, must be 0 or a valid vignette file version (no larger than the default file version). If set to 0 or not specified, the output file is created using the most current file version. Ignored if -info is specified.
Returns version information for this utility. Specify without filename and other options.
