The WAVEDLGPARAMS structure provides information used to initialize the dialog box created by the LDialogImageEffect::DoModalFreeHandWave function. After the user closes the dialog box, this structure is updated with information about the user's selections.

Member	Description
uStructSize	Size of this structure, in bytes. Use the sizeof operator to calculate this value.
pBitmap	Ignored.
bZoomToFit	Flag that indicates the initial zoom level for previewing the image. Possible values are:
	Value	Meaning
	TRUE	Set the initial zoom level to "Zoom to fit".
	FALSE	Set the initial zoom level to "Normal (1:1)".

uAmplitude	Waves magnitude. The values range from 1 to the length of the image's diagonal.
uWaveLen	Value that represents the wave length, if DIS_PER is set in the uWaveFlags parameter. If DIS_FRQ is set in uWaveFlags, this value is the number of repeated waves. Possible values range from 0 – 100.
nAngle	Wave’s rotation angle in hundredths of degrees. The valid range is from –18000 to 18000 (The value in degrees is nAngle divided by 100).
uHorzScale	Size of the horizontal wave, given as a percentage of uAmplitude. The valid range is from 0 to 100.
uVertScale	Size of the vertical wave, given as a percentage of uAmplitude. The valid range is from 0 to 100.
crFill	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.
uWaveFlags	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. The following are the flags that indicate how to handle exposed areas:
	Value	Meaning
	FILL_CLR	[0x0000] fill exposed areas with the color in crFill.
	FILL_RPT	[0x0001] stretch the edges of the image to fill the exposed area.
	FILL_NOCHG	[0x0002] do not change exposed areas.
	The following are the flags that indicate the type of information in the uWaveLen member:
	Value	Meaning
	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.
	The following are the flags that indicate the wave type:
	Value	Meaning
	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.

uDlgFlags	User interface flags for this dialog, which determine the layout and action of the dialog. Possible values are:
	Value	Meaning
	DLG_WAVE_SHOW_CONTEXTHELP	[0x00000002] dialog should contain a context sensitive help icon.
	DLG_WAVE_SHOW_APPLY	[0x00000080] Show the Apply button in the dialog. The dialog will not apply any effect unless the user presses the Apply button.
pfnHelpCallback	Ignored.
pHelpCallBackUserData	Ignored.
