The expand operation substitutes data of one two designated colors the "1" or "0" stored image. first code is substituted all pixels represented by and second "0". This then memory which controls picture shown to user. technique permits commonly used images such as alphanumeric characters various fonts icons compressed form with per pixel. These are formed using at time drawing Otherwise these would need be multiple pixel desired requiring considerable redundant data. may combined selected part that Thus already single operation.
