If you have one of the BLOOMIN8 E-Ink Canvas frames driven by the BLOOMIN8 E-Ink Canvas integration, I made a Lovelace card that lets you change the displayed image straight from your dashboard — with all the image processing done in the browser.
What it does
- Drag & drop or pick a local image.
- Crop-to-content (trims uniform borders), then orientation-aware cover-crop to the panel’s aspect ratio.
- Saturation / gamma / contrast sliders with a live WYSIWYG preview — handy for the limited e-ink palette.
- Single-select destination showing a thumbnail of what’s currently on each panel.
- Battery-friendly: the frame is never polled for previews (cached locally; contacted only on upload or a manual refresh).
- Localizable UI (English default, Greek bundled).
It uploads through the integration’s upload_image_data service. Vanilla JS, no build step, MIT.
