Yes, the current view can be saved as a graphical image in either Bitmap (*.bmp), Portable Network Graphics (*.png) or jpeg (*.jpg or *.jpeg) file formats. To save the current image, hit File in the top-level menu, Save As... in the next menu, then choose the required format in the File Format dialogue box and hit OK. This opens the Save As dialogue box which allows you to specify the name and location of the file to be created. The Save Image dialogue box then appears. This allows you to specify the image size. Please note, sizes over 1500 by 1500 pixels require large amounts of memory.
