virtual L_INT LBitmapBase::ConvertFromWMF(hWMF, uWidth, uHeight)
Converts a Windows metafile (WMF) into a LEAD Technologies bitmap. When this function is completed, there are two copies of the drawing in memory: the WMF and the original LEAD vector. Freeing one will not affect the other.
Handle to the WMF to be converted.
Amount by which to scale the metafiles original width.
Amount by which to scale the metafiles original height.
|SUCCESS||The function was successful.|
|< 1||An error occurred. Refer to Return Codes.|
The metafile can be loaded at the original dimension or scaled by using the uWidth and uHeight parameters.
If uWidth == 0 and uHeight == 0 - the metafile is loaded at the size present in the file
If uWidth == 0 and uHeight > 0 - the metafile is stretched so that it has the height uHeight (preserving the aspect ratio)
If uWidth > 0 and uHeight == 0 - the metafile is stretched so that it has the width uWidth (preserving the aspect ratio)
If uWidth > 0 and uHeight > 0 - the metafile is stretched so that it has the width uWidth and height uHeight (the aspect ratio is ignored)
This example loads a bitmap, converts it to a WMF, then converts the WMF back to a bitmap
L_INT LBitmapBase__ConvertFromWMFExample(HWND hWnd, LBitmap* pLeadBitmap)
LBitmap Bitmap; /* Bitmap handle for the initial image */
/* Load a bitmap, keeping its own bits per pixel */
nRet =Bitmap.Load(MAKE_IMAGE_PATH(TEXT("ImageProcessingDemo\\Image3.cmp")), 0, ORDER_BGR, NULL, NULL);
/* Convert the initial bitmap to a WMF */
hWmf = Bitmap.ConvertToWMF( );
/* Free the initial bitmap */
/* Convert the WMF to create a new LEAD bitmap and preserve the size */
nRet =pLeadBitmap->ConvertFromWMF(hWmf, 0, 0);
/* Clean up */
