Distorts the bitmap with a wave zoomed from the specified center.
#include "ltwrappr.h"
virtual L_INT LBitmap::ZoomWave(uAmplitude, uFrequency, nPhase, uZomFact, pCenter, crFill, uFlags)
Zoom wave magnitude.
The number of repeated waves along the radial line.
Wave phase shift. The valid range is from -36000 to 36000. The real value is nPhase divided by 100.
The percentage the wave grows as it moves from the image center. The valid range is from 0 to 100.
POINT structure that contains the center point from which the wave is zoomed.
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:
Value | Meaning |
---|---|
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. |
Value | Meaning |
---|---|
SUCCESS | The function was successful. |
< 1 | An error occurred. Refer to Return Codes. |
The function applies a sinusoidal wave zoomed from the specified center. 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.
