ShowDisplayDitheringDlg Method

Description:

Shows the Display: Dither dialog. The Display: Dither dialog is as follows:

The drop-down list and check boxes on the left side of the dialog are used to set the dithering parameters for the display of the image.

The user can click the "Preview Changes" checkbox to see the effects of the dithering parameters in the preview area (they can leave the checkbox un-checked if the image is particularly large and therefore takes a long time to render).

Clicking the "OK" button will apply the dithering parameters to the image referenced by thePageDisplay, and then close the dialog. Note that you must specify the hWnd parameter in order for the end-user to see any changes when they click "OK".

Clicking the "Apply" button will apply the dithering parameters to the image referenced by thePageDisplay, but leave the dialog on the screen. Note that you must specify the hWnd parameter in order for the end-user to see any changes when they click "Apply".

Clicking the "Cancel" button will close the dialog without making any changes.
