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

nValue	Amount of stretching where positive values stretch the central pixels toward the edges and negative values stretch the pixels toward the center. Valid range is from –500 to 500.
ptCenter	POINT structure that contains the center of the sphere. 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 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.
uSpherizeFlags	Flags that indicate how to handle exposed areas outside the sphere and inside the sphere. 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 outside the sphere:
	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 how to handle exposed areas inside the sphere:
	Value	Meaning
	FILL_ROT	[0x0000] Rotate the image inside the sphere pattern.
	FILL_WOUTROT	[0x0010] Fill the exposed center of the sphere in the same manner as exposed areas outside the sphere.
	This flag is ignored if the nValue is negative.

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