virtual L_INT LBitmap::Wave (uAmplitude, uWaveLen, nAngle, uHorzFact, uVertFact, crFill, uFlags)
Distorts the bitmap with two perpendicular waves at the specified angle and with the specified wave type.
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.
