Features

• NASA APOD download

  The app fetches NASA's image of the day and saves it locally. If the APOD is not an image, DeskCal falls back to Picsum.photos.

• Calendar generation

  DeskCal creates a calendar image for the current week number, month and year. Sundays are red, and the current date is highlighted.

• Image merging

  The background image and generated calendar are merged into one final wallpaper image.

• Windows wallpaper update

  The merged image is set as the system wallpaper using SystemParametersInfo from the Windows API.
