| <h4>● Overview</h4> |
| Allows to generate a motion parallax movement effect on the Source image, where things in<br> |
| front move faster than things in the back.<br> |
| The image width is stretched to the sides, to transform it into a trapezoid, but it will not<br> |
| be stretched vertically.<br> |
| In other words, the contraction in the vertical direction caused by depth, should be<br> |
| incorporated beforehand in the image.<br> |
| Also, if you want to apply this effect to a moving background, the movement of the background<br> |
| must be collapsed into a SubXsheet.<br><br> |

| <h4>● Parameters</h4> |
| <UL> |
| <LI><b>Vanishing Point</b> : The center point for the deformation. In the case of perspective<br> |
| projection, this is the vanishing point.</LI> |
| <LI><b>Anchor Point</b> : Defines the vertical position that will be the basis for the deformation.<br> |
| Pixels above this point will not be drawn (become transparent).<br> |
| It also defines the horizon line for the deformed image, maintaining the original image width.</LI> |
| <LI><b>Precision</b> : Since the deformation is carried out only by expansion, the resolution will<br> |
| suffer. In order to minimize resolution deterioration, the original image resolution is<br> |
| multiplied by this value before being deformed.<br> |
| There is no point in making Precision higher than the value obtained by dividing the<br> |
| "Capture resolution of the background" by the "Output resolution".</LI> |
