Uploads pre-processed, dithered raw image data for fast, direct-to-screen rendering. This is an advanced feature.
The data is stored in a dedicated directory (not in galleries). The device parses and refreshes the screen immediately upon upload. If uploaded during slideshow mode, the next slideshow cycle is postponed by 5 minutes (300s).
Resolution must match the screen's current physical resolution exactly, or the device will error.
- e.g. EL073TF1 portrait (rotation 1 or 3): 480 x 800
- e.g. EL073TF1 landscape (rotation 0 or 2): 800 x 480
Color palette (6 colors):
| Color | Index | Binary (3-bit) |
|---|---|---|
| Black | 0 | 000 |
| White | 1 | 001 |
| Red | 2 | 010 |
| Green | 3 | 011 |
| Blue | 4 | 100 |
| Yellow | 5 | 101 |
3-bit packing format: Each pixel is represented by 3 bits. Every 3 bytes (24 bits) encode 8 pixels. Pixels are scanned left-to-right, top-to-bottom. Their 3-bit values are concatenated into a continuous bit stream, then split into bytes.
Example: 9 pixels with colors [Red, Yellow, Green, White, Red, Black, White, White, ...]:
- Bit stream:
010 101 011 001 010 000 001 001 ... - Byte 1:
01010101=0x55 - Byte 2:
10010100=0x94 - Byte 3:
00001001=0x09
Data size comparison (e.g. 13.3" screen 1200x1600):
- Uncompressed (1 byte/pixel): 1,920,000 bytes (~1.92 MB)
- 3-bit packed: (1200 × 1600 × 3) / 8 = 720,000 bytes (~703 KB)
