Encoder Options for PGF Files

You may specify a tradeoff between quality and size for PGF files by entering a Quality value.

The Quality value must be within the range 0 to 9. A value of 0 means perfect quality (lossless compression); a value of 9 means maximum compression (i.e. smallest file size).

You may also specify the number of hierarchical levels of image representation for PGF files. This number must be within the range 1 to 10.
