Courier - Version 1.0 A utility to type text messages inside the actual color information of 24-bit color bitmaps. What makes Courier Special? Auto-detection of existing messages. Buried messages are undetectable without a copy of Courier. What Courier does?It User loads a bitmap into memory, Courier converts it to 24-bit color and opens a text window where the user can type a message up to the length allowed by the size of the bitmap. Or, if a message exists, Courier brings up a text window with the existing message and allows the user to save it to disk.
