No need copy the file you want .jpg into a folder and copy imgconvert then run it using g the example provided imgconvert source.ext destination.ext then copy the resultant .h file to your sketch

  1. On Windows PC install Python 3.91 or later, find it here: https://www.python.org/downloads/

  2. Install Python

  3. Create an accessible folder e.g. EPD47 e.g. C:\EPD47 ***Note this folder must be accessible to the cmd pompt A better location might be in your Documents folder usually located at C\Your-Username\Documents, example: Directory of C:\Users\david\EPD47

  4. Copy your source .JPG images to the folder

  5. Transfer the following files to your EPD47 folder - imgconvert.py and fontconvert.py they are located in the EDP47 Library script folder

  6. Install Python 3.91, start a Windows cmd prompt, and chage directory to the folder EPD47: cd C:\Users\david\EPD47

  7. To create an image for display, enter this at the command prompt: imgconvert.py -i sourceimagename.jpg - n requiredname -o outputfile.h

  8. Example convert sunny.jpg to sunny.h imgconvert.py -n sunny -i sunny.jpg -o sunny.h

  9. The image file is now created, include the file in your code like this #include "sunny.h"
