Is there any way to convert BITMAPHANDLE to TStream?

Hi,
Im a Delphi user. Is there any way to convert it without writing to file?

regards

Never mind,
I found the way. If there is anyone interested in;

Var
aSTM:TMemoryStream;
aBitmap :BITMAPHANDLE;
FName :String;
aHandle :THandle;
iSize :L_SIZE_T;
pMem :PChar;
Begin
FName:='c:\A1.JPG';
aHandle:=0;
iSize:=0;
OpenImageFile(@aBitmap,0,FName);
L_SaveBitmapMemory(@aHandle,@aBitmap,FILE_JPEG,aBitmap.BitsPerPixel,20,@isize,nil);

aSTM:=TMemoryStream.Create;
pMem:=GlobalLock(ahandle);
aSTM.Write(pmem[0],iSize);
aSTM.SaveToFile('c:\1.jpg'); //do whatever you want with stream
aSTM.Free;
GlobalUnlock (aHandle);
GlobalFree (aHandle);

end;


I wonder is there any way for L_SaveBitmapList? I have lots of files. Im preparing a bitmap list. Is it possible to save this list to TStream? without saving it to disk?

regards

If you want to save a multi-page image in memory, you can use the L_SaveFileMemory to save the first page in memory, and then save the other pages to the same image (in memory) by passing SAVEFILE_MULTIPAGE flag to the L_SaveFileMemory function.

If this is not what you're trying to do, please give me more details about your requirements.

My problem is convert TStream to BITMAPHANDLE.
I would convert a cmp file in TMemoryStream to BMP format in BITMAPHANDLE, so I can show in TImage instead of Disk.

Is any body know how to do that?
Thx..

dky,

Please don't reopen an old thread that you did not start, because your issue could be different - and it is indeed different in this case. Also, for this particular question, you already started thread 44798 and we gave you an initial reply. I recommend trying the idea we gave you there and if it doesn't work, go back to that thread with a follow up reply.

Thanks,
