Parameter |
Description |
|
|
pBitmap |
Pointer to the bitmap handle referencing the bitmap to be changed. |
|
|
uFlags |
Flags that indicate how to deinterlace the image and whether to remove odd lines or even lines. You can use a bit wise OR (|) to specify one flag from each group. |

DEINTERLACE_NORMAL |
[0x0001]Deinterlace the image by copying the data line into the removed lines. |
|
|
DEINTERLACE_SMOOTH |
[0x0002] Deinterlace the image by averaging the data lines and copying the averaged data into the removed lines. |

Example
/* The following loads a bitmap and applies the deinterlace function to it: */
BITMAPHANDLE LeadBitmap; /* Bitmap handle to hold the loaded image. */
/* Load the bitmap, keeping the bits per pixel of the file */
L_LoadBitmap(TEXT("IMAGE1.CMP"), &LeadBitmap, sizeof(BITMAPHANDLE), 0, ORDER_BGR, NULL, NULL);
/* remove odd lines smoothly */
L_DeinterlaceBitmap(&LeadBitmap, DEINTERLACE_SMOOTH | DEINTERLACE_ODD);
