Changing file names
With Maintain aspect ratio unchecked,
enter values for absolute Width and
Height to make images of a fixed size. As
aspect ratio is not maintained, images may
be stretched horizontally or vertically.
Change the units of measurement to
percent, then enter identical percentage
values to scale Width and Height in
proportion (maintain aspect ratio);
otherwise, different values will stretch
images horizontally or vertically.
Enter a DPI value to alter the original
resolution of the images.
It is also possible to define a Destination File Name for the files to be processed by
selecting the dialog's Modify... button. In the File Name Format dialog you can
select new file names that can be built up using the current date/time, document
names, sequence number, or text string, individually or in combination.
Remember to use the sequence number to generate a separate file for every file to
be converted—otherwise your first converted file will be overwritten continually.
