I have been battling for sometime to get images displaying smoothly in an Adafruit IO Dashboard, but so far to no avail. What I can't work out is why if the image can be visible in the preview panel (Edit Layout / Edit Block / Next Step and then pasting the Base64 string in the test value), the image is not displayed when received live in the Dashboard page itself. I expect I am overlooking something obvious, but I am not sure where to look. I have tried png and jpeg, but no difference. Have also tried various resolutions - the string below is a 50 x 50 image, and while it appears as in the Block Preview window, I do not get the view updated in the Dashboard itself when I receive this, or other similar images.
This is a base64 string:
Code: Select all
/9j/4AAQSkZJRgABAQAAAQABAAD/2wBDAAoHBwgHBgoICAgLCgoLDhgQDg0NDh0VFhEYIx8lJCIfIiEmKzcvJik0KSEiMEExNDk7Pj4+JS5ESUM8SDc9Pjv/2wBDAQoLCw4NDhwQEBw7KCIoOzs7Ozs7Ozs7Ozs7Ozs7Ozs7Ozs7Ozs7Ozs7Ozs7Ozs7Ozs7Ozs7Ozs7Ozs7Ozs7Ozv/wAARCAAyADIDASIAAhEBAxEB/8QAFQABAQAAAAAAAAAAAAAAAAAAAAf/xAAUEAEAAAAAAAAAAAAAAAAAAAAA/8QAFAEBAAAAAAAAAAAAAAAAAAAAAP/EABQRAQAAAAAAAAAAAAAAAAAAAAD/2gAMAwEAAhEDEQA/AIyAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAD/2Q==
This is only a dark image, but appears in the preview window when pasted (via the steps above). This has been copied directly from data received into an Adafruit feed, yet the image is never displayed (I just see the template camera logo).
Any pointers are gratefully appreciated.
