Description This function will generate motion blur noise from the center pixel on the input image. The center motion blur noise can be tuned by the factor of the motion and the distance of the noise in pixels. This function works for only 8 bit per bixel and 24 bit per pixel images.
Examples
The original 180 x 210 pixel image and the motion blured image with iFactor = 50 degrees and iDistance = 10.
Syntax RetVal = [BiFilter.]FilterCenterMotionBlur hDib iAngle iDistance iShowProgress hWnd
Returns RetVal Long The handle of new filtered DIB, 0 if an error occurred, or –1 if the BIFilter.dll does not installed.
Remarks hDIB Long Handle of the image to filter.
iFactor short The factor of motion blur. The larger the iFactor the smaller the noise.
iDistance short The distance of the motion noise in pixels. The larger the distance the larger the noise.
iShowProgress short This parameter specifies the displaying of the progressbar and the preview dialog.
Available values:
DISPLAY_NONE (0) – The progressbar and the preview dialog will not display before filtering.
DISPLAY_PROGRESS (1) – The progressbar will display during filtering procedure.
DISPLAY_DIALOG (2) – The preview dialog will display before filtering. This dialog shows the part of the image before and after filtering.
DISPLAY_BOTH (3) – The progressbar and the preview dialog will display.
IMPORTANT: The preview dialog will only display, if there is BIDlgs32.dll installed.
hWnd Long Handler of the parent window.
