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

pFilter	Address of a variable to be updated with the spatial filter selected in the dialog. The Line Segment filter applies line segment line detection. You can use this filter to find line discontinuities in an image. All pixels not on the detected line segments are changed to black. Choose the appropriate value for horizontal, vertical, left-to-right diagonal, or right-to-left diagonal detection. Possible values are:
	Value
	FLT_LINESEG_HORZ
	FLT_LINESEG_VERT
	FLT_LINESEG_LTOR
	FLT_LINESEG_RTOL
uDlgFlags	User interface flags for this dialog, which determine the layout and action of the dialog. Possible values are:
	Value	Meaning
	DLG_LINESEGMENTFILTER_SHOW_CONTEXTHELP	[0x00000002] dialog should contain a context sensitive help icon.
pfnHelpCallback	Ignored.
pHelpCallBackUserData	Ignored.
