BMP格式转换为WMF格式
procedure BmpToWmf (BmpFile,WmfFile:string);
var
MetaFile : TMetaFile;
MFCanvas : TMetaFileCanvas;
BMP : TBitmap;
begin
{Create temps}
MetaFile := TMetaFile.Create;
BMP := TBitmap.create;
BMP.LoadFromFile(BmpFile);
{Igualemos tama駉s}
{Equalizing sizes}
MetaFile.Height := BMP.Height;
MetaFile.Width := BMP.Width;
{Create a canvas for the Metafile}
MFCanvas:=TMetafileCanvas.Create(MetaFile, 0);
with MFCanvas do
begin
{Draw the BMP into canvas}
Draw(0, 0, BMP);
{Free the Canvas}
Free;
end;
{Free the BMP}
BMP.Free;
with MetaFile do
begin
{Save the Metafile}
SaveToFile(WmfFile);
{Free it...}
Free;
end;
end;
