Gsk.Transform.perspective

### Method

# Gsk Transformperspective

#### Declaration [src]

    GskTransform*
    gsk_transform_perspective (
      GskTransform* next,
      float depth
    )

#### Description [src]

Applies a perspective projection transform.

This transform scales points in X and Y based on their Z value, scaling points with positive Z values away from the origin, and those with negative Z values towards the origin. Points on the z=0 plane are unchanged.

This function consumes `next`. Use `gsk_transform_ref()` first if you want to keep it around.

#### Parameters

`next`

  Type: `GskTransform`

  The next transform.

  The argument can be `NULL`.
  The instance takes ownership of the data, and is responsible for freeing it.

`depth`

  Type: `float`

  Distance of the z=0 plane. Lower values give a more flattened pyramid and therefore a more pronounced perspective effect.

#### Return value

Type: `GskTransform`

The new transform.

The caller of the method takes ownership of the returned data, and is responsible for freeing it.
