RippleTexture Method

Description:

Provides the ripple effect on the image, as if it is looked at through a relief glass. The function uses an image as a ripple pattern. If the scaled ripple pattern image is smaller than the source image, or if offsets are greater than 0, pattern is repeated over the image.

Syntax:

Sub RippleTexture(Page As IGPage, Texture As IGPage, Depth As
Single, Scale As Single, XOffset As Long, YOffset As Long,
smoothness As Single, Invert As Boolean)

Parameters:

Name	Description
Page	IGPage Object to which to apply the effect.
Texture	IGPage Object to use as a ripple pattern.
Depth	Strength of the ripple effect.
Scale	Specifies the scaling factor for pattern image.
XOffset	Horizontal offset at which the upper left corner of the ripple texture shall be placed.
YOffset	Horizontal offset at which the upper left corner of the ripple texture shall be placed.
smoothness	Specifies how much the ripple pattern should be smoothed before applying.
Invert	Inverts the ripple pattern, effectively swapping "convex" and "concave" areas.

Return Value:

N/A

Bits Per Pixel:

All color spaces for image, DibStd for texture. The first channel of the texture is used as ripple mask.
