# ps_shading

(PECL)

ps_shading -- Creates a shading for later use

## Descrição

int ps_shading ( resource psdoc, string type, float x0, float y0, float x1, float y1, float c1, float c2, float c3, float c4, string optlist )

Creates a shading, which can be used by ps_shfill() or ps_shading_pattern().

The color of the shading can be in any color space except for `pattern`.

## Parâmetros

`psdoc`

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

`type`

  The type of shading can be either `radial` or `axial`. Each shading starts with the current fill color and ends with the given color values passed in the parameters `c1` to `c4` (see ps_setcolor() for their meaning).

`x0, x1, y0, y1`

  The coordinates `x0`, `y0`, `x1`, `y1` are the start and end point of the shading. If the type of shading is `radial` the two points are the middle points of a starting and ending circle.

`c1, c2, c3, c4`

  See ps_setcolor() for their meaning.

`optlist`

  If the shading is of type `radial` the `optlist` must also contain the parameters `r0` and `r1` with the radius of the start and end circle.

## Valores de retornado

Returns the identifier of the pattern or `FALSE` in case of an error.
