### xviewer_transform_apply ()

    GdkPixbuf *
    xviewer_transform_apply (XviewerTransform *trans,
                             GdkPixbuf *pixbuf,
                             XviewerJob *job);

Applies the transformation in `trans` to `pixbuf` , setting its progress in `job` .

#### Parameters

trans | a XviewerTransform |
pixbuf | a GdkPixbuf |
job | a XviewerJob |

#### Returns

A new GdkPixbuf with the transformation applied.
