When i've done the changes i want to save the image as a .dwg file, but when i want to open the file AUTOCAD doesnt recognise so i'm not able to open the file on AUTOCAD. Is there any way which i can obtain a correct .dwg file, from a edited image in c#?</P><P>&nbsp;</P><P>This is the code that i'm using to obtain the .dwg file, it works for jpg file, but not for .dwg file</P><P>&nbsp;</P><P>private void Generar_Click(object sender, EventArgs e)<BR />&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; {<BR />&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; SaveFileDialog Guardar = new SaveFileDialog();<BR />&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Guardar.Filter = "DWG(*.dwg)|*DWG|DXG(*.DXG)|*.DXG|JPEG(*.JPG)|*.JPG|BMP(*.BMP)|*.BMP";<BR />&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Bitmap bmp = new Bitmap(pictureBox.Image);<BR />&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Graphics gr = Graphics.FromImage(bmp);<BR />&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Pen p = new Pen(Color.Red);<BR />&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; p.Width = 5.0f;<BR />&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; gr.DrawRectangle(p, 1, 2, 30, 40);<BR />&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; pictureBox.Image = bmp;<BR />&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Image Imagen = pictureBox.Image;<BR />&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Guardar.ShowDialog();<BR />&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Imagen.Save(Guardar.FileName);<BR /><BR />&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; }</P><P>&nbsp;</P><P>Thanks</P><P>&nbsp;</P><P>&nbsp;</P><P>&nbsp;</P><P>&nbsp;</P> Mon, 27 Apr 2015 18:39:28 GMT Anonymous 2015-04-27T18:39:28Z
