Hello to everyone
In Lamw, I want to use an object from the Tbitmap class to use it as a
buffer in the graphics application. I create the object, but when I
want to resize, the program crashes. I am very pleased if there is
information about the reason and its solution.
Respects.

Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i procedure
TAndroidModule1.jButton1Click(Sender: TObject);var  buffer:Tbitmap; //
 Add Uses Graphics,begin  LogDebug('I','Start Op'); 
buffer:=Tbitmap.Create; LogDebug('I','Bitmap Buffer Created'); 
buffer.Width:=512; LogDebug('I','Bitmap Buffer Width Sized'); 
LogDebug('I','Stop Op');end;

You can try LAMW  "jBitmap"

Thank you very much for your reply jmpessoa.
jDrawingView, I want to shorten the drawing process on the long-
lasting process. in that I think I need to use a bitmap as a buffer
object.
The reason I want to use Tbitmap is to have canvas.
Yes, I want to use jbitmap, but I don't have Canvas? Can I add canvas
to Jbitmap? What can be done? I do not know ?
