chcialbym otworzyc plik np. bmp ale za pomocą
blockread
to co ja zrobiłem mozecie tutaj znalezc: - niestety to nie dziala
var
f : file;
l1, l2 : string[10];
width, height : string[5];
stream : tmemorystream;
file_size : integer;
begin
stream := tmemorystream.create;
assignfile(f,filename);
reset(f,1);
blockread(f,l1,sizeof(l1));
blockread(f,l2,sizeof(l2));
blockread(f,width,sizeof(width));
blockread(f,height,sizeof(height));
blockread(f,file_size,sizeof(file_size));
stream.Size := file_size;
BlockRead(F,Stream, stream.size);
closefile(f);
image.Picture.Bitmap.LoadFromStream(stream);
stream.free;
end;
