今天群里讨论对图片进行BASE64编码的问题就简单的写了下。
编码：
procedure TForm1.btn1Click(Sender: TObject,',',');
var
fs :TFileStream;
ss:TStringStream;
begin
fs := TFileStream.Create('1.jpg',fmOpenRead,',',');
ss := TStringStream.Create;
try
TNetEncoding.Base64.Encode(fs,ss,',',');
mmo.Text := ss.DataString;
finally
fs.Free;
ss.Free;
end;
end;
解码：
procedure TForm1.btn2Click(Sender: TObject,',',');
var
ss:TStringStream;
fs:TFileStream;
begin
ss := TStringStream.Create(mmo.Text,',',');
fs := TFileStream.Create('2.jpg',fmOpenWrite + fmCreate,',',');
try
TNetEncoding.Base64.Decode(ss,fs) ;
finally
fs.Free;
ss.Free;
end;
end;
