# ps_setmiterlimit

(PECL ps >= 1.1.0)

ps_setmiterlimit — Sets the miter limit

### 说明

ps_setmiterlimit ( resource `$psdoc` , float `$value` ) : bool

If two lines join in a small angle and the line join is set to PS_LINEJOIN_MITER, then the resulting spike will be very long. The miter limit is the maximum ratio of the miter length (the length of the spike) and the line width.

### 参数

`psdoc`

  Resource identifier of the postscript file as returned by ps_new().

`value`

  The maximum ratio between the miter length and the line width. Larger values (> 10) will result in very long spikes when two lines meet in a small angle. Keep the default unless you know what you are doing.

### 返回值

成功时返回 `TRUE`， 或者在失败时返回 `FALSE`。
