Part Number: Image2Code
The big thing that this program adds is complete flexibility in the byte orientation and scan direction.
The 8-bit operation is fairly straight-forward, simply drop an 8-bit indexed image into the program, Select the scan direction, select Assembly or C, and click "convert". The output will be shown in notepad, ready to copy into your program.
The 1-bit ("bitmap") version is a bit more complex, but follows the same general flow. You have complete flexibility in choosing the orientation of the bits so they can match your LCD's internal memory configuration. If your LCD's pixel dimensions are not an even multiple of 8 bits (rare, but does happen on occasion), you can choose the edge that gets clipped.
