L_LTIMGEFX_API L_INT L_MotionBlurBitmap(pBitmap, uDim, nAngle, bUnidirectional, uFlags)
Applies a filter, which creates the illusion of movement in an image.
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.
Required DLLs and Libraries
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);
