Taking the Mold

Image Data Preparation

1. Open the target image folder.

2. Import an image sequence.

3. Select Batch Conversion — this converts each frame (128×64 = 1024 bits) into a 16-bit.c file.

4. All generated.c files are stored in the batch folder.

5. Copy the bitmap data from each.c file and merge into a single file named images.h.
