_VIDEO_POINTER_CAPABILITIES structure

Description

The VIDEO_POINTER_CAPABILITIES structure contains capabilities of the screen pointer.

Members

`Flags`

A set of flags that specify certain capabilities of the pointer. Flags can be a combination of the following values.

Flag	Meaning
VIDEO_MODE_ASYNC_POINTER	The pointer can be updated asynchronously to drawing operations.
VIDEO_MODE_MONO_POINTER	A monochrome hardware pointer is supported.
VIDEO_MODE_COLOR_POINTER	A color hardware pointer is supported.
VIDEO_MODE_ANIMATE_START	The current pointer has the same hotspot as the previous pointer.
VIDEO_MODE_ANIMATE_UPDATE	The current pointer has the same hotspot as the previous pointer.

`MaxWidth`

Specifies the maximum width of the pointer, in pixels.

`MaxHeight`

Specifies the maximum height of the pointer, in pixels.

`HWPtrBitmapStart`

Specifies the first offset, in CPU-addressable units, in the memory bitmap that is used to store the hardware pointer bitmap. A value of –1 is not valid.

`HWPtrBitmapEnd`

Specifies the last offset, in CPU-addressable units, in the memory bitmap that is used to store the hardware pointer bitmap. A value of –1 is not valid.
