ps_get_parameter — Gets certain parameters

### 说明

ps_get_parameter ( resource `$psdoc` , string `$name` [, float `$modifier` ] ) : string

Gets several parameters which were directly set by ps_set_parameter() or indirectly by one of the other functions. Parameters are by definition string values. This function cannot be used to retrieve resources which were also set by ps_set_parameter().

The parameter `name` can have the following values.

fontname

  The name of the currently active font or the font whose identifier is passed in parameter `modifier`.

fontencoding

  The encoding of the currently active font.

dottedversion

  The version of the underlying pslib library in the format <major>.<minor>.<subminor>

scope

  The current drawing scope. Can be object, document, null, page, pattern, path, template, prolog, font, glyph.

ligaturedisolvechar

  The character which dissolves a ligature. If your are using a font which contains the ligature `ff' and `|' is the char to dissolve the ligature, then `f|f' will result in two `f' instead of the ligature `ff'.

imageencoding

  The encoding used for encoding images. Can be either hex or 85. hex encoding uses two bytes in the postscript file each byte in the image. 85 stand for Ascii85 encoding.

linenumbermode

  Set to paragraph if lines are numbered within a paragraph or box if they are numbered within the surrounding box.

linebreak

  Only used if text is output with ps_show_boxed(). If set to `TRUE` a carriage return will add a line break.

parbreak

  Only used if text is output with ps_show_boxed(). If set to `TRUE` a carriage return will start a new paragraph.

hyphenation

  Only used if text is output with ps_show_boxed(). If set to `TRUE` the paragraph will be hyphenated if a hypen dictionary is set and exists.

hyphendict

  Filename of the dictionary used for hyphenation pattern.
