Converts a Windows enhanced metafile (WMF) into a LEAD Technologies bitmap. When this function is completed, there are two copies of the drawing in memory: the EMF and the original LEAD vector. Freeing one will not affect the other.
virtual L_INT LBitmapBase::ConvertFromEMF(hEMF, uWidth, uHeight)
Handle to the EMF 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 enhanced metafile can be loaded at the original dimension or scaled by using the uWidth and uHeight parameters.
If uWidth == 0 and uHeight == 0 - the enhanced metafile is loaded at the size present in the file.
If uWidth == 0 and uHeight > 0 - the enhanced metafile is stretched so that it has the height uHeight (preserving the aspect ratio).
If uWidth > 0 and uHeight == 0 - the enhanced metafile is stretched so that it has the width uWidth (preserving the aspect ratio).
If uWidth > 0 and uHeight > 0 - the enhanced 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 EMF, then converts
the EMF back to a bitmap
L_INT LBitmapBase__ConvertFromEMFExample(LBitmap *pLeadBitmap)
LBitmap Bitmap; /* Bitmap handle for the initial image */
/* Load a bitmap, keeping its own bits per pixel */
Bitmap.Load(MAKE_IMAGE_PATH(TEXT("ImageProcessingDemo\\Image3.cmp")), 0, ORDER_BGR, NULL, NULL);
/* Convert the initial bitmap to a EMF */
hEMF = Bitmap.ConvertToEMF();
/* Free the initial bitmap */
/* Convert the EMF to create a new LEAD bitmap and preserve the size */
nRet =pLeadBitmap->ConvertFromEMF(hEMF, 0, 0);
/* Clean up */
