Description

VARIANT_BOOL

Enabled

Enables or disables the Unsharp Mask effect. If set to VARIANT_FALSE, the filter will pass the video samples intact.

VARIANT_BOOL

UseDefaultAutoRadius

Indicates whether to use the default value of the Radius property. If set to VARIANT_TRUE, the value of the Radius property is ignored.

VARIANT_BOOL

UseDefaultThreshold

Indicates whether to use the default value of the Threshold property. If set to VARIANT_TRUE, the value of the Threshold property is ignored.

Long

UnsharpMask

Gets or sets the amount of sharpening. Possible values range from 0 to 500. For any value below the lower limit, a minimum value of 0 will be used. For any value beyond the upper limit, a maximum value of 500 will be used. The default value is 250.

Long

Radius

Gets or sets the radius value. This value indicates the size of the neighborhood used for blurring each pixel of the video sample.

Possible values range from 1 to 100. For any value below the lower limit, a minimum value of 1 will be used. For any value beyond the upper limit, the maximum value of 100 will be used. The default value is 1.

Long

Threshold

Gets or sets the threshold value. This value indicates the threshold for modifying the original value of the pixel. If the difference in the original pixel value and the blurred pixel value is greater than the threshold value, the original pixel value will be modified. Possible values range from 0 to 255. For any value below the lower limit, a minimum value of 0 will be used. For any value beyond the upper limit, the maximum value of 255 will be used. The default value is 0.

VARIANT_BOOL

IsLEADInputPinConnected

Read only. Gets the filter’s input pin connection state. VARIANT_TRUE if connected, and VARIANT_FALSE otherwise.

VARIANT_BOOL

IsLEADOutputPinConnected

Read only. Gets the filter’s output pin connection state. VARIANT_TRUE if connected, and VARIANT_FALSE otherwise.

long

InWidth

Read only. Gets the input video stream width in pixels. Should hold the same value as the OutWidth property.

long

InHeight

Read only. Gets the input video stream height in pixels. Should hold the same value as the OutHeight property.

long

OutWidth

Read only. Gets the output video stream width in pixels. Should hold the same value as the InWidth property"x-text-underline: normal; /*begin!kadov{{*/ text-decoration: underline; /*}}end!kadov*/ ">.

long

OutHeight

Read only. Gets the output video stream height in pixels. Should hold the same value as the InHeight property.

long

InBits

Read only. Gets the input video stream bits per pixel. Should hold the same value as the OutBits property.

long

OutBits

Read only; get the input video stream bits per pixel. Should hold the same value as the InBits property.
