The LOCALHISTOEQUALIZEDLGPARAMS structure provides information used to initialize the dialog box created by the LDialogColor::DoModalLocalHistoEqualize 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)".
nWidth	The width of the local histogram equalizer rectangle, in pixels. The width should be more than zero.
nHeight	The height of the local histogram equalizer rectangle, in pixels. The height should be more than zero.
nXExtention	The extension of the width of the local histogram equalizer rectangle, in pixels.
nYExtention	The extension of the height of the local histogram equalizer rectangle, in pixels.
uType	Flag that indicates which color space to equalize. Possible values are:
	Value	Meaning
	RGB_SPACE	[0x0001] Linearize the number of pixels across the RGB color space. (Separated channels)
	YUV_SPACE	[0x0002] Linearize the number of pixels across the YUV color space. (Best results)
	GRAY_SPACE	[0x0004] Linearize the number of pixels per gray level in a gray level representation of the image.

uSmooth	Size of the area to be used when smoothing the edges between localized blocks. Possible values range from 0 to 7, but if nHeight is less than or equal to 7 then the maximum value for this item is nHeight - 1.
uDlgFlags	User interface flags for this dialog, which determine the layout and action of the dialog. Possible values are:
	Value	Meaning
	DLG_LOCALHISTOEQUALIZE_SHOW_CONTEXTHELP	[0x00000002] dialog should contain a context sensitive help icon.
	DLG_LOCALHISTOEQUALIZE_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.
