HANDLE CALLBACK FilterCenterMotionBlur( HDIB hDIB,
int iFactor,
int iDistance,
int iShowProgress,
HWND hParent)
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.
Parameters
|
HDIB |
hDIB |
Handle of the DIB to filter. |
|
int |
iFactor |
The factor of motion blur. The larger the iFactor the smaller the noise. |
|
int |
iDistance |
The distance of the motion noise in pixels. The larger the distance the larger the noise. |
|
int |
iShowProgress |
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 BiDlgs.dll installed. |

HWND |
hParent |
Handler of the parent window. |
Return values
The handle of the new filtered DIB or NULL if an error occurred.
