The IG_save_...() family of functions is complementary to the IG_load_...() functions. The IG_save_...() functions allow you to save images to disk files or to memory, convert files from one file format to another, and to append or insert images as pages to a multi-page file. All IG_save_...() functions have the lFormatType parameter in common. This allows you to choose which ImageGear-supported file format and compression type (where applicable) to which to save. Whereas some functions, such as IG_info_get_ex(), have separate parameters for the format and compression types, the saving functions have one parameter that covers both.
