graphics.scaletranform() method

[codeadair]

Hello Everyone! I am programming graphic program.i use doublebuffer technology to draw graphic to bitmap object.Using e.Graphics().DrawImage(bmp, 0, 0) to draw bitmap object to panel in panel paint event.It's really good idea.Thanks to Dave Kreskowiak. I do need to zoom in\out the graphic.and i use e.Graphics.ScaleTransform(xscaletran, yscaletran) in panel.paint event to do it.But problem happens.pen size changed too. i think i know something about it.The method graphics.scaletransform just draught\extrude the graphics physically. Do i have to redraw bitmap to zoom in\out the graphic? Thanks for all replies! Best regards! ICQ:258-235-734 MSN:msnadair@hotmail.com
