| Option | Argument | Description |
|---|
| -o | file | Write output to file rather than to stdout. |
| -name | name | Create an external initialization function with name. |
| -threshold | level | Specifies a threshold level (as a percentage) to use when deciding whether to compress a file. If the reduction in the file size is greater than the threshold level, it is compressed; otherwise, the uncompressed data is stored instead. The default threshold level is 70%, meaning that compressed files which are 30% or less of their original size are stored as compressed data. |
| -compress | level | Compress input files to the given compression level, which is an integer in the range 1 to 9. Level 1 does the least compression but is fastest. Level 9 does the most compression but is slowest. To turn off compression, use -no-compress. The default value for level is -1, which means use zlib's default compression level. |
| -root | path | Prefix the resource access path with path. The default is no prefix. |
| -no-compress | | Disable compression. |
| -binary | | Output a binary file for use as a dynamic resource. |
| -version | | Display version information. |
| -help | | Display usage information. |
