The SATURATIONDLGPARAMS structure provides information used to initialize the dialog box created by the LDialogColor::DoModalSaturation function. After the user closes the dialog box, information about the user's selections are updated in this structure.

Members

uStructSize

Size of this structure, in bytes. Use the sizeof operator to calculate this value.

uDlgFlags

User interface flags for this dialog, which determine the layout and action of the dialog. Possible values are:

Value Meaning
DLG_SATURATION_AUTOPROCESS [0x00000001] process the image on OK. The pBitmap member of this structure should contain a valid bitmap.
DLG_SATURATION_SHOW_CONTEXTHELP [0x00000002] dialog should contain a context sensitive help icon.
DLG_SATURATION_SHOW_PREVIEW [0x00000004] show a preview of the image in the dialog. The pBitmap member of this structure should contain a valid bitmap.
DLG_SATURATION_SHOW_TOOL_ZOOMLEVEL [0x00000008] show the "Zoom to fit" and "Zoom Normal" toolbar buttons. The DLG_SATURATION_SHOW_PREVIEW flag must be set in order to show these buttons.
