HTUI_DeviceColorAdjustment function (winddi.h)
The HTUI_DeviceColorAdjustment function can be used by graphics device drivers to display a dialog box that allows a user to adjust a device's halftoning properties.
Syntax
LONG HTUI_DeviceColorAdjustment(
[in, optional] LPSTR pDeviceName,
[in] PDEVHTADJDATA pDevHTAdjData
);
Parameters
[in, optional] pDeviceName
Caller-supplied pointer to a NULL-terminated string representing a displayable device name.
[in] pDevHTAdjData
Caller-supplied pointer to a DEVHTADJDATA structure.
Return value
The function returns the following values:
Return code | Description |
---|---|
|
The user chose the dialog box's OK button. |
|
The user chose the dialog box's Cancel button. |
|
An error occurred. |
Remarks
A graphics driver interface, such as a printer interface DLL, can call the HTUI_DeviceColorAdjustment function to display a dialog box that allows a user to view and modify the device's halftoning properties. Depending on member values specified for the DEVHTADJDATA structure, the function will either enable the dialog box for user modification or just display caller-specified default values. If user modification is allowed, the function returns the modified parameters to the caller (using the DEVHTAJDATA structure), so the driver can pass them to the device.
