It is fine if you are going to continue to work with the image in SuperPaint later. However, we often intend to export these drawings into other software. Frequently we will then import the graphic into Photoshop for final work and conversion to our eventual format. This issue is often encountered in doing graphic and multimedia work. Frequently we want to move files from one program to another.
Most programs normally use proprietary formats that are tied to the particular application.
For example, both Superpaint and Photoshop have their own formats that most other programs cannot read. Formats that are not linked to one specific application are called generic. Examples of generic formats include JPEG, GIF, BMP, PICT, amd MP3. These formats are read and written by many programs but often do not support all the things that can be encoded in proprietary fiormat files. For example, you cannot preserve separate layers in Photoshop files that are saved as JPEG or GIF files.
