The TRANSITIONDLGPARAMS structure provides information used to initialize the dialog box created by the LDialogEffect::DoModalGetTransition 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.
uTransition	The transition to use. Possible values are
	Value	Meaning
	EFX_TRANS_SOLID	Solid filling
	EFX_TRANS_HORZ_LINE	Horizontal lines
	EFX_TRANS_VERT_LINE	Vertical lines
	EFX_TRANS_DOWNWARD_DIAG	Downward diagonal lines
	EFX_TRANS_UPWARD_DIAG	Upward diagonal lines
	EFX_TRANS_CROSS	Cross lines
	EFX_TRANS_DIAG_CROSS	Diagonal cross lines

crBack	The background color or the starting gradient color, if a gradient transition is used. 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.
crFore	The foreground color or the ending gradient color, if a gradient transition is used. 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.
uSteps	Number of steps in the gradient.
uEffect	The effect to use. For a list of possible values, refer to Effect Types.
uGrain	The grain size, in pixels.
uDelay	The delay, in milliseconds
uMaxPass	The maximum number of passes.
bTransparent	Flag that indicates whether to use a transparent color. Possible values are:
	Value	Meaning
	TRUE	Use the transparent color specified in crTransparent.
	FALSE	Do not use a transparent color.

crTransparent	The transparent color. 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.
uWandWidth	The wand width, in pixels.
crWand	The wand color. 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.
uDlgFlags	User interface flags for this dialog, which determine the layout and action of the dialog. Possible values are:
	Value	Meaning
	DLG_TRANSITION_SHOW_CONTEXTHELP	[0x00000001] dialog should contain a context sensitive help icon.
	DLG_TRANSITION_AUTOPREVIEW	[0x00000004] auto preview when options change
	DLG_TRANSITION_FORECOLOR	[0x00000008] fore color is an option
	DLG_TRANSITION_BACKCOLOR	[0x00000010] back color is an option
	DLG_TRANSITION_DELAY	[0x00000020] transition delay is an option
	DLG_TRANSITION_GRAIN	[0x00000040] transition grain is an option
	DLG_TRANSITION_EFFECT	[0x00000080] paint effect is an option
	DLG_TRANSITION_PASSES	[0x00000100] transition passes is an option
	DLG_TRANSITION_WAND	[0x00000200] wand is an option
	DLG_TRANSITION_TRANSPARENT	[0x00000400] transparency is an option
	DLG_TRANSITION_GRADIENT	[0x00000800] gradient is an option
pfnHelpCallback	Ignored.
pHelpCallBackUserData	Ignored.
