Saves frames to a virtual frame file.


SVF bframe eframe file



beginning frame number to save (default=1)


ending frame number to save (default=bframe)


file name in which to save the frames; if you don't specify an extension, .PIX is automatically appended


SVF saves the image, graphics, frame directory, navigation, image enhancements and the graphics tables from all frames specified in the bframe to eframe range. For example, SVF 1 10 LOOP saves those components from image frames 1 through 10 and graphics frames 1 through 10 into the file LOOP.PIX. Thus, when you restore the frames with the RVF command, full image and graphics functionality are retained so you can use commands like EG, ERASE, EU, GU, K and W. If you're running a session with independent graphics, you can also use commands like SF, SG, J and Y to display or loop the restored image and graphics frames independently.

If multiple frames are saved, they can be of different sizes. However, when the RVF command is used to restore them, the frames specified in RVF must be the same size as the saved frames. Command LVF with FORM=ALL lists the size of each of the saved frames so you can restore them to frames of the correct size with RVF.

Saved frames can also have multiple panels as long as an image and/or graphic is displayed in every panel. When a saved frame with multiple panels is restored with the RVF command, the frame that it's restored to acquires the panel configuration of the saved frame. For example, if a saved frame with 4 panels is restored with RVF to a single-panel frame, the frame is reconfigured to have 4 panels.

Because SVF saves all image and graphics information and saves frames of any size and panel configuration, you can use it to save all of your images and graphics into a single file, then restore them at a later time for additional work or to show for demonstration purposes.

Frames saved with SVF on little endian workstations (e.g., PC systems) can only be restored with RVF on the same workstation or other little endian workstations. Likewise, frames saved with SVF on big endian workstations (e.g., Sun SPARCstations and IBM RS/6000s) can only be restored with RVF on the same workstation or other big endian workstations.

Use the RVF command to restore these files to frames. Use the LVF command to list virtual frame files.



This entry saves image and graphics frames 1 through 5 into the file PICTURE.PIX.
