bufferDepth property

Gets or sets the number of bits per pixel used for colors in the off-screen bitmap buffer.

Syntax

HRESULT value = object.put_bufferDepth( v);HRESULT value = object.get_bufferDepth(* p);

Property values

Type: long

0

Default. No explicit buffering occurs. The IHTMLScreen::colorDepth property is set to the screen depth.

-1

Buffering occurs at screen depth. The IHTMLScreen::colorDepth property is set to the screen depth.

1, 4, 8, 15, 16, 24, 32

Number of bits per pixel to use for the off-screen buffer. The IHTMLScreen::colorDepth property is also set to this value. The value 15 specifies 16 bits per pixel, in which only 15 bits are used in a 5-5-5 layout of RGB values.

Standards information

There are no standards that apply here.

Remarks

Nonsupported values cause IHTMLScreen::bufferDepth to be set to -1.

When IHTMLScreen::bufferDepth is -1 and the user changes system settings that affect the screen depth, the buffer depth is automatically updated to the new depth. This is not the case if IHTMLScreen::bufferDepth is set to a specific value.
