WarpCornerPinComp In the S_WarpsComp Plugin. Performs a 3D perspective warp of the source image to align the corners with the four indicated points. This can be useful for positioning the source over an object in another clip, such as a billboard or computer screen. Inputs: Front:  The clip to use as foreground. Back:  The clip to use as background. Matte:  Specifies the opacities of the Front clip.

Parameters:

Top Left:   X & Y,   Default: [160 380],  Range: any.
Location of the upper-left corner of the source. This parameter can be adjusted using the Top Left Widget.

Bottom Left:   X & Y,   Default: [70 200],  Range: any.
Location of the lower-left corner of the source. This parameter can be adjusted using the Bottom Left Widget.

Top Right:   X & Y,   Default: [580 400],  Range: any.
Location of the upper-right corner of the source. This parameter can be adjusted using the Top Right Widget.

Bottom Right:   X & Y,   Default: [500 55],  Range: any.
Location of the lower-right corner of the source. This parameter can be adjusted using the Bottom Right Widget.

Filter:   Check-box,  Default: on.
If enabled, the image is adaptively filtered when it is resampled. This gives a better quality result when parts of the image are warped smaller.

Bulge:   X & Y,   Default: [0 0],  Range: -1 to 1.
Distorts the perspective of the warped image, so that it appears to bulge in one direction. A value of 1 gives no distortion. A value of less than one causes the image to stretch toward the upper/right corner, while a value of greater than one causes it to stretch to the lower/left corner.

Wrap:   X & Y,  Popup menu,  Default: [NO NO].
Determines the method for accessing outside the borders of the source image.

NO:  gives black beyond the borders.

TILE:  repeats a copy of the image.

REFLECT:  repeats a mirrored copy. Edges are often less visible with this method.

Comp Premult:   Check-box,  Default: off,  Shared.
Enable this for a better composite if the Foreground pixel values have been pre-multiplied by the Matte pixel values. This is also known as an 'additive' composite.
