# esp32camOverlay

[Example sketch](src/esp32camOverlay/esp32camOverlay.ino)  to show, how to draw text or lines on a esp32-cam captured photo and save the picture on a SD card.

This could be useful, for example, if you want to show a timestamp, logo or label on a photo. Due memory limitations no resolution higher then XGA (1024x768) is possible with 4 MB psram. If you get incomplete jpg images reduce the jpg quality.

 

Example:
