save() and saveFrame()

Using save() with one argument (a filename ending with 
TIFF, TARGA, JPEG, or PNG) will allow you to save the current
image into your sketch's folder. (It won't go to the data
folder, but rather into the main folder.)

The basic syntax is:
  save(fileNameString);
... which looks like
  save("myImage.tif");

Use any of the following file extensions:
.tif, .tga., .jpg, or .png.

.tif is largest and highest-quality;
.tga and .png look medium quality and small;
.jpg will be very low-quality and small.


If you want to save a series of images, use saveFrame instead. 
This works about the same way, except that you can give #### as places
where the numbers can go, so using this:
  saveFrame("myFrame-####.tif"); 

will save your frames as:
myFrame-0000.tif
myFrame-0001.tif
etc.

If you don't give any arguments to saveFrame, it will save your frames as
screen-0000.tif
screen-0001.tif
etc.
