Applies a filter, which creates the illusion of movement in an image.
L_LTIMGEFX_API L_INT L_MotionBlurBitmap(pBitmap, uDim, nAngle, bUnidirectional, uFlags)
Pointer to the bitmap handle that references the bitmap to blur.
Size of the blur effect, in pixels.
Value that represents the direction of the motion, in hundredths of a degree (+/-) This value can be a number from 0 to 36000. If the value is positive, the motion will be clockwise. If the value is negative, the motion is counter-clockwise.
Flag that indicates whether the motion extends only in one direction. Possible values are:
|TRUE||The motion blur effect is only in the direction specified in
|FALSE||The motion blur effect is along the line with that angle. For example, if nAngle is 0, the blur effect will occur in the 0 degree direction and the 180 degree direction.|
Reserved for future use. Must be 0.
|SUCCESS||The function was successful.|
|< 1||An error occurred. Refer to Return Codes.|
This function does not support signed data images. It returns the error code ERROR_SIGNED_DATA_NOT_SUPPORTED if a signed data image is passed to this function.
This function supports 12 and 16-bit grayscale and 48 and 64-bit color images. Support for 12 and 16-bit grayscale and 48 and 64-bit color images is available in the Document and Medical Imaging toolkits.
This function does not support 32-bit grayscale images. It returns the error code ERROR_GRAY32_UNSUPPORTED if a 32-bit grayscale image is passed to this function.
Win32, x64, Linux.
This example loads a bitmap and creates motion blur.
BITMAPHANDLE LeadBitmap; /* Bitmap handle to hold the loaded image. */
/* Load the bitmap, keeping the bits per pixel of the file */
nRet = L_LoadBitmap (MAKE_IMAGE_PATH(TEXT("sample5.cmp")), &LeadBitmap, sizeof(BITMAPHANDLE), 0, ORDER_BGR, NULL, NULL);
/* blur the bitmap */
nRet = L_MotionBlurBitmap(&LeadBitmap,20,4500,FALSE, 0);
nRet = L_SaveBitmap(MAKE_IMAGE_PATH(TEXT("Result.BMP")), &LeadBitmap, FILE_BMP, 24, 0, NULL);
