|---|---|---|---|
| drawIcon | bi-colour array | (0-127) X 8 | Data vertically addressed |

- Bitmap Size (in KiB)= (Image Width×Image Height×Bits Per Pixel)/(8×1024)
- Pixel size column assumes 128 by 128 screen.
- The mentioned bitmap data arrays for images are created with this file data conversion tool
- For drawBitmap16 and DrawBitmap24 easier just to use image files direct from file system rather than arrays see examples showing BMP file usage.
- These class functions will return an error code in event of error, see API for more details.
