virtual L_INT LBitmap::Ripple (uAmplitude, uFrequency, nPhase, uAttenuation, CenterPt, crFill, uFlags)
Warps the image in concentric rings.
Wave magnitude (amount of displacement).
Number of repeated waves along the radial line.
Wave phase shift, in hundredths of degrees. The valid range is from -36000 to 36000 (The value in degrees is nPhase divided by 100).
Attenuation value. The attenuation value indicates how rapidly the wave amplitude decays as the wave travels along the radial line. The values range from 0 - 1000.
POINT structure that contains the center of the Ripple wave.
The COLORREF value that specifies the fill color for any exposed areas. You can specify a COLORREF value, such as the return value of the Windows RGB macro, or you can use the PALETTEINDEX macro to specify a palette color.
Flag that indicates how to handle exposed areas. Possible values are:
|FILL_CLR||[0x0000] Fill any exposed areas with crFill.|
|FILL_RPT||[0x0001] Stretch the image edges to fill the exposed area.|
|FILL_NOCHG||[0x0002] Leave the exposed area as is, without changing it.|
|SUCCESS||The function was successful.|
|< 1||An error occurred. Refer to Return Codes.|
This function will warp the image as a series of rings radiating out from the CenterPt. The center point must be defined inside the bitmap or inside the region, if the bitmap has a region.
If the bitmap has a region, the effect will be applied on the region only.
This function supports 12 and 16-bit grayscale and 48 and 64-bit color images. Support for 12 and 16-bit grayscale and 48 and 64-bit color images is available only in the Document/Medical toolkits.
This function does not support signed data images. It returns the error code ERROR_SIGNED_DATA_NOT_SUPPORTED if a signed data image is passed to this function.
This function does not support 32-bit grayscale images. It returns the error code ERROR_GRAY32_UNSUPPORTED if a 32-bit grayscale image is passed to this function.
L_INT LBitmap__RippleExample(LAnimationWindow * LAniWnd)
CenterPt.x = (LAniWnd->GetHandle ())->Width/2;
CenterPt.y = (LAniWnd->GetHandle ())->Height/2;
return LAniWnd->Ripple(20, 10, 0, 0, CenterPt, 0, FILL_RPT);
