L_LTDIS_API L_INT L_ConvertFromWMF2(pBitmap, uStructSize, hWmf, uWidth, uHeight, clrBackground)
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.
Pointer to the bitmap to be updated with the converted file.
Size in bytes, of the structure pointed to by pBitmap
, for versioning. Use sizeof(BITMAPHANDLE).
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.
Specifies the color used to fill the background.
Value | Meaning |
---|---|
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.
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)
