The WAVESHEARDLGPARAMS structure provides information used to initialize the dialog box created by the LDialogImageEffect::DoModalWaveShear 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)".

pAmplitudes	Array of integers that represent shear wave values. The valid value of each element in pAmplitudes array is between ©1000 and 1000. These values are obtained through the Wave Shear Dialog, or, for image processing; they may be obtained from the LBitmap::GetCurvePoints function. The toolkit will allocate this buffer for the user on function return. You should free this pointer using GlobalFree function unless you called the LDialogBase::EnableAutoProcess.
uAmplitudesCount	Number of entries in the pAmplitudes array.
uScale	Factor used to decrease the various amplitude values in the pAmplitudes array. Each value in the pAmplitudes array is multiplied by this factor. The real factor value is the uScale value divided by 100. Therefore, to multiply the amplitude values by 1.0, set this parameter to 100.The values range (1-100).
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.
uWaveShearFlags	Flags that indicate how to handle exposed areas, and the direction of the shear wave. You can use a bit wise OR (\|) to specify one flag from each group. The following are the flags that indicate how to handle the 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 exposed areas.
	FILL_NOCHG	[0x0002] do not change or process exposed areas.
	The following are the flags that indicate the direction of the shear wave:
	Value	Meaning
	SHR_HORZ	[0x0000] apply the shear wave horizontally.
	SHR_VERT	[0x0010] apply the shear wave vertically.

uDlgFlags	User interface flags for this dialog, which determine the layout and action of the dialog. Possible values are:
	Value	Meaning
	DLG_WAVESHEAR_SHOW_CONTEXTHELP	[0x00000002] dialog should contain a context sensitive help icon.
pfnHelpCallback	Ignored.
pHelpCallBackUserData	Ignored.
