LEADTOOLS Filters Help

This filter has no specific data types, but includes the following enumeration for use with its programming interface:
enum REFERENCE_FRAME
{
REF_USEBUFFER,
REF_USENEXTFRAME,
REF_USECOLOR,
};
|
Type |
Name |
Description |
|
VARIANT_BOOL |
Enabled |
Enables or disables the effect. If set to VARIANT_FALSE, the filter will pass the video samples intact. |
|
long |
Hue |
Value used to change the color of the effect. Hue is a color wheel (360 degree). Range: 0 to 360. |
|
VARIANT_BOOL |
LineNoise |
Show/hide a noise line. |
|
long |
Noise |
Gets or sets the noise density. Range: 1 to 100. |
|
VARIANT_BOOL |
FirstFrameIsReference |
Enables or disables setting the first frame in every play session as the reference frame. If this is VARIANT_TRUE, the first frame in every play session will be set as the reference frame (Usually the first frame in a movie). If this property is VARIANT_FALSE, then the reference frame should be set manually after a number of frames. Setting this property after the stream starts will have no effect. |
|
long |
Threshold |
Value used to control an object's detection level. A lower threshold provides stronger object detection. Range : 1 to 100. |
|
VARIANT_BOOL |
NoReferenceFrame |
Flag that controls the reference frame. If this property is VARIANT_TRUE, the reference frame is assumed to be a black buffer. If it is VARIANT_FALSE, the reference frame will be the frame set by the user through theSetReferenceFrame method or by setting the FirstFrameAsReference property. |
Parameters
|
pBuffer |
buffer contains the reference frame. This buffer should have the same dimensions (width and height), and the same bits per pixel as the movie. |
|
|
lRGBColor |
pixel color (RGB 24-bit). The reference frame will be set as a solid frame with the color specified in this parameter. |
|
|
opt |
flag that controls the reference frame. Possible values are: |
|
|
|
Value |
Meaning |
|
|
REF_USEBUFFER |
only the pBuffer member is used. |
|
|
REF_USENEXTFRAME |
the next frame in the movie is taken as the reference frame. |
|
|
REF_USECOLOR |
the lRGBColor parameter is used. |
Description
Sets the reference frame of the movie.
Return
S_OK if connected, S_FALSE otherwise.
