Saving a copy of the current GIF picture

Select "Write GIF as" from the File menu, or press Command-G to write a copy of the GIF, MacPaint or PCX picture being currently displayed. You can use this to make copies onto your hard disk (or a floppy disk) of favourite pictures that you see whilst scanning a CDROM. In effect, this is the same as making a note of the file name, and using the Finder to copy the file from the CDROM to your disk. Please note that you should not infringe any copyright that might pertain to the image being copied.


File formats-GIF or TIFF

When writing a copy of a GIF picture you are given two or three choices of file format:

  1. GIF (Graphics Interchange Format) - this is the fastest and probably the smallest option, fastest because it is just a copy of the original GIF picture, which is already compressed. Smallest because GIF pictures are always stored internally with LZW compression. This option is greyed out and unavailable if the picture you are viewing is a MacPaint, BMP,TGA, PCC or PCX picture - these can only be saved as TIFF pictures.
  2. TIFF - use the TIFF (Tagged Image File Format) if you want to import a copy of the picture into a word processor, desktop publishing program, or graphics program that does not support GIF pictures. TIFF pictures are more widely supported than GIF pictures, particularly by Macintosh programs. Once you have decided to use the TIFF format, you have a choice of compressed or uncompressed files.
    • TIFF compressed files are saved using LZW compression (similar to GIF pictures). A TIFF compressed picture will be a similar size to a GIF picture. The compression (and decompression later on when loading the picture into another program) makes this format slightly slower to use than uncompressed TIFF images).
    • TIFF uncompressed files tend to take two to three times as much disk as TIFF compressed. However they are faster to save, and load later on. Also, some other programs may not support TIFF compressed pictures. If you cannot load a TIFF compressed picture into another program, try the TIFF uncompressed option.

Only GIF, MacPaint, BMP, TGA, PCC and PCX pictures can be saved

At present, you can only save copies of GIF, MacPaint, BMP, TGA, PCC and PCX pictures as described above. Although this version of QuickSlideshow can read TIFF and PICT files as well, it is not designed to save copies of those formats. The reasons for this are:
