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

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	Zoom wave magnitude. The value must be greater than zero.
uFrequency	The number of repeated waves along the radial line.The value must be greater than zero.
nPhase	Wave phase shift. The valid range is from –36000 to 36000.
uZoomFactor	The percentage the wave grows as it moves from the image center. The valid range is from 0 to 100.
ptCenter	POINT structure that contains the center point from which the wave is zoomed. The center point must be defined inside the bitmap, or inside the region, if the bitmap has a region.
crFill	The COLORREF value that specifies the fill color of undefined area. 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.
uZoomWaveFlags	Flags that indicate how exposed areas will be handled. Possible values are:
	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_NOCHANGE	[0x0002] do not change exposed areas.

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