Distorts the bitmap with two perpendicular waves at the specified angle and with the specified wave type.
virtual L_INT LBitmap::Wave (uAmplitude, uWaveLen, nAngle, uHorzFact, uVertFact, crFill, uFlags)
Waves magnitude. The values range from 1 to the length of the image's diagonal.
Value that represents the wave length, if DIS_PER is set in the uFlags parameter. Possible values range from 1 to 100 and give the wavelength as a percentage of the bitmap dimensions. If DIS_FRQ is set in uFlags, this value is the number of repeated waves.
Waves rotation angle in hundredths of degrees. The valid range is from -18000 to 18000 (The value in degrees is nAngle divided by 100).
Size of the horizontal wave, given as a percentage. The valid range is from 0 to 100.
Size of the vertical wave, given as a percentage. The valid range is from 0 to 100.
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.
Flags that indicate how to handle exposed areas, the type of information in the uWaveLength parameter and the wave type. You can use a bitwise OR ( | ) to specify one flag from each group.
|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.|
|DIS_PER||[0x0000] The value in uWaveLen is a wavelength given as a percent of the bitmap dimensions. If this value is used, the valid range of uWaveLen is from 0 to 100.|
|DIS_FRQ||[0x0010] The value in uWaveLen is the frequency, or the number of times the wave repeats.|
|WV_SIN||[0x0000] The wave is a sinusoidal wave.|
|WV_COS||[0x0100] The wave is a sinusoidal wave shifted by 90 degrees.|
|WV_SQUARE||[0x0200] The wave is a square wave.|
|WV_TRIANG||[0x0300] The wave is a triangular wave.|
|SUCCESS||The function was successful.|
|< 1||An error occurred. Refer to Return Codes.|
The function applies two perpendicular waves. The uHorzFact and uVertFact parameters control the size of these waves.
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.
