Working with PNG data
#5
I didn't know that this problem could be solved by Indy, so I wrote to the Delphi forum. And in the end I solved the problem without Indy. Thanks again.

uses pngimage, EncdDecd
procedure TfmViewQRC.ShowQRC(mContent: String);
var
mStream1 : TMemoryStream;
mStream2 : TMemoryStream;
mPng : TPngobject;
begin
mStream1 := TMemoryStream.Create;
mStream2 := TMemoryStream.Create;
mPng := TPNGObject.Create;
try
mStream1.WriteBuffer(mContent[1],Length(mContent)*SizeOf(Char));
mStream1.Position:=0;
DecodeStream(mStream1,mStream2);

mStream2.Position := 0;
mPng.LoadFromStream(mStream2);
Image1.Canvas.Draw(0,0,mPng);
finally
mStream1.Destroy;
mStream2.Destroy;
mPng.Destroy;
end;
end;
