Help needed Mahesh

Question

Dear Mahesh I'am trying to develop an image annotation component in which i got a picturebox to display image.The basic functionalities are rotating the imagedrawing basic shapes such as rectangleellipselines etc over the image. I'am thru with rotating the image.The code used 4 that is given below float temp = AI.Width; AI.Width = AI.Height; AI.Height = temp; temp = pictureBoxTIFF.Width; pictureBoxTIFF.Width = pictureBoxTIFF.Height; pictureBoxTIFF.Height = (int)temp; image.RotateFlip(RotateFlipType.Rotate270FlipNone); But now the problem comes into play.... I'am trying 2 draw a rectangle on the image and rotating the image...But the rectangle is not getting rotated...Could u tell me some APIFunctions which can do the thing... Or in more clear terms the rectangle is not highlighting the area which it should be after rotation.Could u tell me how to rotate the rectangle along with the image... Is ther any wayz of gluing the rectangle to the image??? I tried out with using Graphics object from the image...But it'z showing an exception that Graphics object could not be created from an image having indexed pixel format!!!! Could u help me out of this problems... Regards mmx_nexus

Hi I think it is not possible because when u rotate the image you are redrawing the image of the pictureBox and this calls the refresh method of the pictureBox and removes the rectangle that you have drawn. I would suggest that u bind the coordinates and dimensions of the rectangle that u have already drawn to the edges of the image and call the refresh method of pictureBox and redraw the rectangle. In mean time if you have any idea u are welcome to post the solution bye
