pip install -r requirements.txt. - Run the program
python heat_pype.py. - From the UI, click
Select Image.- The source image is previewed on the left, with the output displayed on the right.
- Click and drag on the source image to crop the output, the result will be displayed in real time.
- Click and drag again to select a new crop.
- Right Click and drag to move the crop around without changing its size.
- Aspect ratio is not maintained, and strange ratio crops can be used for creative effect.
- Set the Com port and Baud Rate from the dropdowns in the top-left corner.
- Com port options should be self populating, if you don't see any listed make sure your USB to Serial adapter is operational or your serial port is connected properly.
- Click print to send the dithered image data to the printer, depending on the baud rate used this may take a moment.
