CairoContext::deviceToUserDistance -- cairo_device_to_user_distance — Transform a distance

### 説明

オブジェクト指向型 (method):

public CairoContext::deviceToUserDistance ( float `$x` , float `$y` ) : array

手続き型:

cairo_device_to_user_distance ( CairoContext `$context` , float `$x` , float `$y` ) : array

Transform a distance vector from device space to user space. This function is similar to CairoContext::deviceToUser() or cairo_device_to_user() except that the translation components of the inverse Cairo Transformation Matrix will be ignored when transforming (`x`,`y`).

### パラメータ

`context`

  A valid CairoContext object created with CairoContext::__construct() or cairo_create()

`x`

  X component of a distance vector

`y`

  Y component of a distance vector

### 返り値

Returns an array with the x and y values of a distance vector in the user-space
